The Stability

Existing routing protocols for hybrid wireless mesh network neglect the negative impact on network lifetime and route stability caused by energy constraints and mobility of mesh clients. To solve this issue, a regional energy- and mobility-aware routing protocol is proposed in this article. Both energy and mobility features in hybrid wireless mesh network are considered in this routing protocol. On one hand, within the communication transmission range, the intensity and degree of dispersion in energy consumption can be perceived. The node whose neighbor area has sufficient energy can be selected for network services, which can balance energy and extend the network lifetime. On the other hand, the mobility of clients is considered to enhance the stability and reduce network overhead. Therefore, regional energy- and mobility-aware routing protocol can balance network energy consumption, prolong network lifetime, and improve route stability. Simulation results via NS2 show that regional energy- and mobility-aware routing protocol can achieve better performance significantly.

Since the wireless mesh network topology dynamics and the radio channels instable, the design of wireless mesh network routing protocol become one of the key factors to determine the performance. This paper mainly studied the existing several kinds of typical three-layer mesh network routing protocol (DSDV and AODV), aimed at the defects of three-layer routing limited to the network topology changes, the paper proposed a network model based on two-layer routing. Forwarding the packet, establishing and maintaining the communication links are accomplished on the Mac layer. Simulation tests showed that two-layer routing has a big improvement on the efficiency of packet forwarding, and it effectively reduced the routing overhead and end-to-end delay simultaneously.

Topology Control has been shown to provide several benefits to wireless ad hoc and mesh networks. However these benefits have largely been demonstrated using simulation-based evaluations. In this paper, we demonstrate the negative impact that the PlainTC Topology Control prototype has on topology stability. This instability is found to be caused by the large number of transceiver power adjustments undertaken by the prototype. A context-based solution is offered to reduce the number of transceiver power adjustments undertaken without sacrificing the cumulative transceiver power savings and spatial reuse advantages gained from employing Topology Control in an infrastructure wireless mesh network. We propose the context-based PlainTC+ prototype and show that incorporating context information in the transceiver power adjustment process significantly reduces topology instability. In addition, improvements to network performance arising from the improved topology stability are also observed. Future plans to add real-time context-awareness to PlainTC+ will have the scheme being prototyped in a software-defined wireless mesh network test-bed being planned.

Aodv Routing Protocol

PMP-AODV routing protocol which introduces priority setting, multi-point relay and path stability is proposed. The algorithm message format is discussed, the MPR selection algorithm is elaborated, the measurement of stability of path is designed, and the working flow of PMP-AODV is analyzed. The simulation result shows that the PMP-AODV protocol is less packet loss rate and lower end-to-end delay than original AODV protocol under the large wireless Mesh network.
