Abstract: The objective is to optimize WMN (Wireless Mesh Network) routing protocol OLSR (Optimized Link State Routing). Although OLSR has link quality extensions, which makes calculating a routing table based on link quality. However when the extension is deployed into the Wireless Mesh Network in the underground coal mine, we find it brings too much cost both in calculation and bandwidth.
