abstract = {Abstract—This paper analyzes and evaluates the Distributed Node Consensus Protocol (DNCP), a state synchronization mech- anism developed by the IETF Homenet working group. DNCP enables network function automation for home networks, which are growing in size and complexity. The basic mechanisms of DNCP are studied in this paper, including the state abstraction, synchronization process and keep-alive mechanism. The over- head is analyzed in single-link topology type. To evaluate the performance of DNCP in more complex scenarios, a reference implementation of DNCP is integrated into ns3 simulator. The convergence time and transmission overhead in various topology types are measured. Based on the obtained results, the correctness of DNCP is verified, and the behavior of DNCP can be concluded.},

abstract = {Typical routing protocols maintain, in their RIB (Routing Information Base) entries permitting destination-based forwarding: for a given data packet, the choice of next hop is a function of the destination address only. However, in deployments where a given network is multi-homed, and where ingress filtering is commonly applied, a routing protocol is required to be able to provide routes so as to forward a data packet (i) to the destination address of the data packet, while (ii) routing through the gateway for which the source address of the data packet is topologically correct. This is called source-destination routing. This paper presents an extension to the Optimized Link State Routing Protocol version 2 (OLSRv2), providing support for such source-destination routing. In a multi- homed network, this OLSRv2 extension provides routes for data packets based also on the source prefix announced by the gateways. The extension is interoperable with unextended OLSRv2. The performance of this extension is quantified by way of simulation studies.

abstract = {Data delivery across a multi-hop low-power and lossy networks (LLNs) is a challenging task: devices participating in such a network have strictly limited computational power and storage, and the communication channels are of low capacity, time-varying and with high loss rates. Consequently, routing protocols finding paths through such a network must be frugal in their control traffic and state requirements, as well as in algorithmic complexity – and even once paths have been found, these may be usable only intermittently, or for a very short time due to changes on the channel. Routing protocols exist for such networks, balancing reactivity to topology and channel variation with frugality in resource requirements. Complementary compo- nent to routing protocols for such LLNs exist, intended not to manage global topology, but to react rapidly to local data delivery failures and (attempt to) successfully deliver data while giving a routing protocol time to recover globally from such a failure. Specifically, this paper studies the “Depth-First Forwarding (DFF) in Unreliable Networks” protocol, standardised within the IETF in June 2013. Moreover, this paper proposes optimisations to that protocol, denoted DFF++, for improved performance and reactivity whilst remaining fully interoperable with DFF as standardised, and incurring neither additional data sets nor protocol signals to be generated.},

A reactive protocol, LOADng – as a basic mode of operation – offers discovery and maintenance of hop-by-hop routes and imposes a state in intermediate routers proportional to the number of traffic paths served by that intermediate router. This paper offers an extension to LOADng, denoted LOADng-PA (Path Accumulation). LOADng-PA is designed with the motivation of requiring even less state in each intermediate router, and with that state being independent on the number of concurrent traffic flows carried. Another motivation the design of LOADng-PA is one of monitoring and managing networks: providing more detailed topological visibility of traffic paths through the network, for either traffic or network engineering purposes.},

abstract = {“The Trickle Algorithm” is conceived as an adaptive mechanism for allowing efficient and reliable information sharing among nodes, communicating across a lossy and shared medium. Its basic principle is, for each node, to monitor transmissions from its neighbours, compare what it receives with its cur- rent state, and schedule future transmissions accordingly: if an inconsistency of information is detected, or if few or no neighbours have transmitted consistent information “recently”, the next transmission is scheduled “soon” – and, in case consistent information from a sufficient number of neighbours is received, the next transmission is scheduled to be “later”. Developed originally as a means of distributing firmware updates among sensor devices, this algorithm has found use also for distribution of routing information in the routing protocol RPL, standardised within the IETF for maintaining a routing topology for low-power and lossy networks (LLNs). Its use is also proposed in a protocol for multicast in LLNs, denoted “Multicast Forwarding Using Trickle”. This paper studies the performance of the Trickle algorithm, as it is used in that multicast protocol.},

abstract = {Jittering (a small, random variation in timing of control message emission) is widely used in protocols for wireless communication, in order to avoid simultaneous packet transmis- sions over the same channel by adjacent nodes in the network. Used for both regularly scheduled packets, for event-triggered packets, and for scheduled resets in the network, jittering is a particularly important mechanism when a network event may cause multiple adjacent nodes to react concurrently. Introduced in the proactive MANET routing protocol OLSR, the “LLN On-demand Ad hoc Distance-vector Routing Protocol - Next Generation” (LOADng), a derivative of AODV, is specified so as to also use jitter for flooding Route Request (RREQ) messages during route discovery. This use of jitter in RREQ flooding is, however, not without drawbacks, which are identified and addressed in this paper within the framework of a more general study of jitter mechanisms used for route discovery in reactive routing protocols. The paper studies the behavior of route discovery when using “naive” jitter (simply, delaying RREQ retransmission by a small uniformly distributed random delay), in order to identify and analyze the problems hereof, mostly related to route sub-optimality and excessive control traffic overhead. A Window Jitter mechanism is then proposed to address these issues – with the performance hereof, when compared to “naive” jitter being evaluated by way of modeling, theoretical analysis and experiments. The paper shows that the use of Window Jitter improves indeed the efficiency of route discovery in AODV and overcome the drawbacks identified for “naive” jitter.},

abstract = {Jitter is a small, random variation of timing before message emission that is widely used in non-synchronized wireless communication. It is employed to avoid collisions caused by simultaneous transmissions by adjacent nodes over the same channel. In reactive (on-demand) routing protocols, such as AODV and LOADng, it is recommended to use jitter during the flooding of Route Request messages. This paper analyzes the cost of jitter mechanisms in route discovery of on-demand routing protocols, and examines the drawbacks of the standard and commonly used uniformly distributed jitter. The main studied drawback is denominated delay inversion effect. Two variations on the jitter mechanism --window jitter and adaptive jitter-- are proposed to address this effect, which take the presence and the quality of traversed links into consideration to determine the per-hop forwarding delay. These variations allow to effectively reduce the routing overhead, and increase the quality of the computed paths with respect to the standard uniform jitter mechanism. Simulations are also performed to compare the performance of different jitter settings in various network scenarios.},

abstract = {LOADng is an on-demand routing protocol, derived from AODV, simplified for use in lossy, low-power and constrained environments, where the ability for devices to communicate is a commodity to their primary function, and where therefore not only the communications channel offers limited capacity, but also the resources available to the device’s communica- tions subsystem are limted. LOADng simplifies AODV in a number of ways, notably the route discovery process by removing intermediate/gratuitous Route Replies – sacrificing that functionality in order to attain smaller control messages and less router state and processing. Alas, this comes at an expense: in some situations, LOADng produces increased control traffic overhead (as com- pared to AODV), and more control messages transmissions means tapping into the device’s limited resources. This paper presents a simple mechanism by which to integrate Expanding Ring flooding into LOADng. The mechanism is described, and the result of simulation studies are presented, showing that both in scenarios with “point-to-point” (any-to-any) traffic and in scenarios with “multipoint-to-point” (all traffic sent to the same destination, as in a data acquisition sensor network) traffic, considerable savings in control traffic overhead can be achieved – without loss in data delivery ratios.},

abstract = {The Ad hoc On-demand Distance-Vector routing protocol (AODV) was published in 2003 by the IETF, as ex- perimental RFC 3561. This routing protocol was one of four routing protocols, developed by the IETF for use in mobile ad hoc networks (MANETs) – with the other being DSR, TBRPF and OLSR. As operational experiences with these protocols accumulated, the IETF set forth on standardization of OLSRv2, a successor to OLSR, and DYMO – with DYMO being the intended successor to DSR and AODV. Alas, while there was traction for and standardization of OLSRv2, interest in, development, standardization, and use of DYMO in MANETs slowly withered. AODV did, however, attract interest for routing in Low-power Lossy Networks (LLNs) due to its limited state requirements. Since 2005, several proposals for simplifying and adapting AODV specifically for LLNs emerged, in 2011 and 2012 with the use of one such adaptation of AODV in the G3-PLC standard for power line communications in smart grids, and with efforts within the IETF emerging towards a single LOADng specification, as next version of AODV. This paper presents this development – from AODV, as specified in RFC3561 – to LOADng. While the basic operation remains unchanged, LOADng presents simplifications, and additional features and flexibilities are introduced. This paper studies the impact of these changes “from AODV to LOADng”, and observes that LOADng unites simplification, flexibility and performance improvements.},

Besides the usage of a suitable routing protocol, the video quality can be further enhanced by using the scalable encoding feature of Scalable Video Coding (SVC) combined with Unequal Error Protection (UEP). SVC is an extension of the H.264/AVC video compression standard used for high-quality video bitstreams encoding, providing spatial, temporal and quality scalability. To evaluate video quality, the Video Quality Metric (VQM) is used. We chose 5 different video contents for our simulations characterized by various temporal and spatial complexities. These video references are taken from the Video Quality Expert Group (VQEG). The results show that multipath routing combined with UEP can effectively improve the quality of video communication over MANET in terms of VQM and successful video decoding.},

abstract = {Multi-Path OLSR is an extension of the single path routing protocol OLSR. The QoS has been demonstrated in simulation and testbed. In this paper, we attempt to confirm those results at the application layer specially for critical applications as video services over wireless networks. The standard H264/SVC is chosen for its enormous potential in video delivery in lossy networks. Still vulnerable to packet losses, we combine the scalable source coding to an Unequal Error Protection (UEP) scheme in order to improve a simple Quality of Experience (QoE) measurements i.e PSNR. In a new simulation framework called SVCEval, the combination of path diversity and scalable protection insures a significant 2 dB gain in QoE for sensitive contents and mobile scenarios in comparison with just MP-OLSR. Within the same context, single path strategy delivers non acceptable video services as soon as nodes are mobile.

abstract = {If deployments of Mobile Ad Hoc Networks (MANETs) are to become common outside of purely experimental settings, protocols operating such MANETs must be able to preserve network integrity, even when faced with careless or malicious participants. A first step towards protecting a MANET is to analyze the vulnerabilities of the routing protocol(s), managing the connectivity. Understanding how these routing protocols can be exploited by those with ill intent, countermeasures can be developed, readying MANETs for wider deployment and use. One routing protocol for MANETs, developed by the Internet Engineering Task Force (IETF) as a multicast routing protocol for efficient data dissemination, is denoted "Simplified Multicast Forwarding'' (SMF). This protocol is analyzed, and its vulnerabilities described, in this paper. SMF consists of two independent components: (i) duplicate packet detection and (ii) relay set selection, each of which presents its own set of vulnerabilities that an attacker may exploit to compromise network integrity. This paper explores vulnerabilities in each of these, with the aim of identifying attack vectors and thus enabling development of countermeasures.},

abstract = { MP-OLSR is a multipath routing protocol based on OLSR (Optimized Link State Routing). The multipath routing protocol is expected to provide more stable routes for the network. In this paper, several topics about MP-OLSR are discussed. We begin with introducing the functionalities of MP-OLSR, which includes topology sensing, routing computation, route recovery and loop detection. Then a testbed is implemented to verify the availability of MP-OLSR. Given OLSR one of the most populated proactive protocols for ad hoc networks, the compatibility between MP-OLSR and OLSR is also discussed. The results based on simulator and our testbed show that MP-OLSR could offer more stable data transmission over the unstable wireless interface. And it could cooperate well with the established OLSR protocol.},

abstract = {Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data without reliance on a fixed base station or a wired backbone network, which makes routing a crucial issue for the design of a ad hoc networks. In this paper we discussed a hybrid multipath routing protocol named MP-OLSR. It is based on the link state algorithm and employs periodic exchange of messages to maintain topology information of the networks. In the mean time, it updates the routing table in an on-demand scheme and forwards the packets in multiple paths which have been determined at the source. If a link failure is detected, the algorithm recovers the route automatically. Concerning the instability of the wireless networks, the redundancy coding is used to improve the delivery ratio. The simulation in NS2 shows that the new protocol can effectively improve the performance of the networks.
