A performance improvement of OLSR for wireless mesh networks

Based on studying the characteristics of topology and business model of wireless mesh networks, depth analysis of the suitable routing protocol type for WMN was given out which shows that proactive hop-by-hop routing is most suitable for WMN. On the basis of Optimized Link State Routing which is a typical proactive hop-by-hop routing protocol. A routing protocol P-OLSR of perceptive 1inks is proposed based on OLSR routing protocol. The protocol detects and analyzes the node load, and link delivery ratio, and link availability, and collects the quality evaluation of path links among the nodes on the network to achieve the selection of routing enhance the throughput of the network, and improve the load balance. The simulation results show that P-OLSR can improve the packet delivery rate of wireless Mesh networks and reduce the average end-to-end delay.
