Weiren Shi · Chuangan jishu xuebao · 2010
A optimal heterogeneous sensor differentiated deployment schemes based on simulated annealing algorithm is proposed to solve the problems of the high density of distributing heterogeneity nodes in wireless sensor networks(WSNs) and geographical irregularity of the sensed event.The algorithm uses the cost of sensors deployment as objective function in the context of assuring the coverage and fault tolerant of networks.Finally,simulation results demonstrated that the proposed approach is suitable for solving deployment problems of heterogeneous WSNs.
