Abstract—Wireless mesh networks are being deployed not only in various industrial fields but also in particular service required areas such as wireless access networks, disaster area, hot spot zone, and the area where fast network construction is required. In these cases, since the mesh node power supply is limited and the channel interference range is related to the transmission power of the nodes, the proper transmission power should be selected to maintain the network connectivity and minimize inter-channel interference. In the paper, the proposed heuristic algorithm, called Topology Controlled Channel Assignment with power control (TCCA), measures the received and transmitted power using a beacon packet and allocates the best channel with the highest SINR value for the HWMP (Hybrid Wireless Mesh Protocol) routing protocol in a real-time basis. We evaluate the networks throughput, end-to-end delay performance of the TCCA algorithm using the NS-3 network simulator. From the simulation studies, we show that the TCCA algorithm outperforms a SINR based channel assignment with the same transmission power.
