【 摘 要 】

Wireless mesh network is a flexible, low cost and multi-purpose networking platform with wired infrastructure connected to the internet. In WMN nodes often have a limited battery supply to use for the sending and reception of transmissions. Routing protocols over WMN are an important issue and many proposals have been addressed to efficiently manage topology information, to offer network scalability and to prolong network lifetime. Optimized Link State Routing (OLSR) is a proactive type of routing which presents the advantage of finding a route between two nodes in the network in a very short time. It can consume lot of energy resources in selecting the Multi-point Relays (MPRs) and exchanging Topology Control information. To overcome this, we present a mechanisms for the OLSR routing protocol to improve its energy performance in Wireless Mesh Networks. We propose a Minimum Battery Draining Rate Aware (MDRA-OLSR) algorithm which utilizes the information collected by OLSR at every node in providing better network connectivity. We propose a modification in the MPR selection mechanism of OLSR protocol, based on the Willingness concept, in order to increase the network lifetime without losses of performance such as PDR, throughput etc. We consider both available energy and battery draining rate metric as a key criteria to select MPR in a set of MPRs. A comparison of an OLSR and MDRA-OLSR protocol is performed. The experiments are simulated using NS3 simulator by considering various situations such as changing speed of nodes, data rate and packet size by keeping the nodes position static and moving nodes dynamically. In this paper, we present the related works on utilization of energy as metric in routing, proposed model, simulation and discussions of the model in Wireless Mesh Networks.
