Abstract
Abstract—Based on Wireless Mesh Network (WMN) theory, according to the characteristics of Wireless Sensor Network (WSN) clustering topology, WSN and WMN are combined to construct Wireless Mesh Sensor Network (WMSN) topology. In order to improve the performance of energy-efficiency, throughput and delay in WMSN, this paper designs a Multi-hop TDMA Energy-efficient Sleeping MAC (MT-MAC) protocol and gives the performance simulation with MATLAB. In MT-MAC, a TDMA frame was divided into a number of time slots for sensor nodes in WMSN to send or receive data packets. As the simulation result shows, compared with SMAC protocol, MT-MAC not only saves 25% energy consumption of the network, but also decreases 45% latency of the whole network.
