Abstract: Wireless Mesh Sensor Networks(WMSN) topology structure was constructed by combining Wireless Sensor Networks with Wireless Mesh Networks. Energy consumption in the high-density WMSN could be decreased by putting the partial sensor nodes into sleeping state and the energy holes problem could be solved by balancing the network energy consumption. This paper proposed a balanced-energy sleeping scheduling scheme based on alternating cluster head nodes in WMSN. hhe sleeping probability of sensor nodes in balanced-energy network was obtained by building cluster head alter-nated model when different sensor nodes took turns to be cluster head. Analytical and simulation resups show that the scheme assures the network coverage, extends the lifetime and balances the energy consumption compared with Randomized Scheduling scheme.
