“…(3) Reactive Hybrid scheme: This is a hybrid mesh network, in which mesh clients use a reactive on-demand routing protocol, AODV, to establish connections to mesh nodes. Similar approaches have been proposed in [23] and [27]. The Reference scheme provides the base performance to evaluate the other techniques.…”

Vehicular ad-hoc network (VANET) is one of the most transforming technologies for Intelligent Transportation Systems today. In particular, wireless mesh network is widely used for VANETs due to its scalability, flexibility, and low maintenance cost. When a mesh node in such a network fails, one can simply replace it with a new mesh node, and the network automatically reconfigures itself. However, due to the environment or limited resources, it may not be feasible to replace a failed node immediately. We have witnessed over the last few years many disasters in the globe. One thing that all of those natural disasters have in common, besides the tremendous loss of life, is that they are immediately followed by an almost total loss of the ability to communicate with outside world. In the recent event of natural disaster in Japan, the communication network was still not fully recovery after weeks of the disaster. However, communication is the key to post-disaster survival. Therefore, it is important to have an alternate communication during time of disaster. In this paper, we introduce two techniques, virtual router approach and virtual link approach, for designing failure-resilient VANET's that can retain almost their original coverage and capacity until the failed mesh nodes can be repaired or replaced, i.e., we are able to retain 80 % of original capacity with only 50 % working mesh nodes. We give simulation results, validated by analytical analysis, to show that this desirable property can be achieved, using virtual routers and/or virtual links, with minimal overhead. These virtual frameworks also balance the workload among the mesh nodes even when the mesh clients are not uniformly distributed over the application terrain. This characteristic helps improve the overall end-to-end delay and communication throughput of the network.

“…HMesh [13] combines OLSR [14] and AODV, and uses them among mesh routers and mesh clients separately. HDV [15] makes use of tree-based routing in infrastructure WMN, and uses AODV in client WMN. Both HMesh and HDV only use the hop count as the routing metric, neglecting network condition.…”

Effective routing protocols considering network features can improve network performance dramatically. As hybrid wireless mesh network (WMN) is composed of static mesh routers and mobile mesh clients, hybrid routing protocol fits hybrid WMN well. However, the existing hybrid routing protocols designed for hybrid WMN do not fully consider the regional network condition, and as a result cannot effectively improve network performance as a whole. In this paper, a load and energy aware hybrid routing protocol (LE-HRP) is proposed. In LE-HRP, gateway-and clientoriented traffic are considered respectively. The queuing delay which can measure the load condition is taken into account in both traffic types. In the process of calculating delay, both physical and logical interferences are considered. In addition, for client-oriented traffic, as energy of mesh clients is limited, in addition to reducing delay, the energy efficiency is also improved in the meantime. A mesh client with low energy can still be used if it can help the network reduce the delay significantly and sufficiently. Otherwise, a mesh client with more residual energy will be chosen. Simulation results through NS3 show that LE-HRP achieves better network performance.

“…However, they inherit the existing challenges in proactive and reactive protocols. Actually, the problem is that they use proactive or reactive protocols in both mobile and fixed (static) nodes simultaneously [1,40] without paying enough attention to their mobility behaviors. Hence, the side effects of proactively broadcasting RREQ in mobile nodes in a high dynamic network cause new challenges to the system such as high traffic, waste of available bandwidth, and more interferences.…”

In recent years, video streaming over wireless mesh networks (WMNs) has been of great interest among the users. In WMNs, although node mobility and scalability are the two most important well-known advantages by end-users, they can decrease the perceived video quality on receivers with increasing the probability of path failure, especially when the number of mobile mesh nodes and their mobility speeds increase. Therefore, the necessity of employing an efficient routing protocol to consider the effects of node mobility is inevitable. Moreover, the interference can be sharply increased, especially on the gateways, when there are many mobile mesh nodes in a WMN. Interference does not permit the system to support many STA and mobile mesh nodes. In order to cope with these challenges, this study introduces and evaluates a good hybrid routing protocol for data dissemination which efficiently and effectively routes packets in a wireless mesh network and intelligently employs proactive and reactive routing protocols based on the node mobility (GREENIE) for efficient video streaming over WMNs and extensively compares it with other routing protocols including hybrid wireless mesh protocol, proactive, reactive, and spanning trees using OMNET++ simulator. GREENIE intelligently distinguishes mobile from static nodes and selects the most stable path between a source and a destination which leads to higher perceived video quality on receivers. The results show the impact of GREENIE on the perceived video quality so that it considerably outperforms other routing protocols in terms of the total number of successfully received packets, the end-to-end delay, and the imposed routing overhead on the system. One of the main advantages of GREENIE is that it performs routing in the medium access control layer without applying any change in the functions of the internet protocol layer.
