Link quality routing protocols and metrics for multi-hop multi-radio wireless Mesh networks

Abstract

There has been intense interest in the worldwide deployment of wireless mesh networks during the past few years. Along with wireless mesh networks deployment, the wireless user is also expected to expand dramatically. The Optimized Link State Routing (OLSR) is a routing protocol developed for MANET and standardized by IETF, which uses Multipoint Relays (MPRs) to forward control messages, minimizing the protocol overhead. The scope of this project is to modify the OLSR protocol in order to store the neighbor’s link quality and consider the MPR selection of a node. This project consider in multihop multi-radio WMNs environment. In multi-radio WMNs the performance can improve through the distribution of traffic through better links, chosen according to an MPR selection heuristic to favor the quality of the links.
