Modified Optimized Link State Routing (M-OLSR) for Wireless Mesh Networks

Abstract

Wireless mesh networks (WMNs) are a type of radio-based network systems which require minimal configuration and infrastructure. One of the factors that influence the performance of WMNs is the underlying routing protocol used. Here, we propose one such routing protocol, called M-OLSR, which is a variant of OLSR, a traditional link-state protocol developed to meet the requirements of mobile adhoc networks MANETs. Our approach improves the throughput and packet delivery ratio, while minimizing routing overhead and delay, by choosing a stable path for packet forwarding through static routers. Simulation results demonstrate that, for WMNs, the M-OLSR outperforms OLSR in terms of throughput, packet delivery ratio, and routing overhead.
