Energy Cost Based Topology Control Algorithm of Minimum-Total-Weight Connected Dominating Set in WSNs
WSNs中基于能量代价的最小权和支配集拓扑控制算法

In this paper, defining energy cost function constructed by remain energy, neighborhood numbers and communication cost of nodes as topology weight to synthetically reflect the energy efficiency of dominator and the contribution of reduced whole energy consumption, an Energy Cost based topology control algorithm for Minimum-total-weight Connected Dominating Set (ECMCDS) is proposed to solve the problem that the energy consumption of minimum connected dominating set is not minimum. The algorithm locally selects the node with a low-weight undertaking dominating mission to construct minimum-total-weight dominating set, and minimums the total energy consumption of networks. The experimental results show that the algorithm not only has the energy saved characters, but also ensures the reliability of topology links and extends the network life-cycle efficiently.
