Refinement of AODV routing algorithm for wireless mesh networks (WMNs)

摘要

Wireless Mesh Networks (WMNs) has recently gained popularities due to their fast and economical ways to access to the Internet. Because the WMNs are one of the few commonly implemented types of the ad hoc networks (MANETs), general MANET routing protocols can be used in the WMNs. it also is expected that a protocol that takes the particularities of the WMNs into account will outperform the general protocol. In this paper, we present a reactive routing protocol, called AODV-Mesh, for the WMNs. This protocol is an extension of a common ad hoc routing protocol to be compatible with the specifications of the WMNs. In addition, we discuss the route recovery mechanism of this protocol in two cases; using the local repair mechanism (AODV-Mesh), and not using the local repair mechanism (AODV-Mesh NoLR). Our simulation results show that not using the local repair mechanism in the AODV-Mesh algorithm improves the performance and efficiency.
