| Abstract: | A new game theoretical topology control algorithm in wireless sensor networks was proposed. The utility function was designed considering the node degree, the residual energy and the transmit power of nodes. The goal of the algorithm was to maximize the utility function by adjusting the per node transmit power that the topology satisfies the connectivity. The existence of the NE (nash equilibrium) was prored. Simulation results show that the algorithm can adjust the transmit power automatically according to the residual energy of the nodes and maximize the energy efficiency. The nodes having more energy can get larger node degree or connect with remote nodes. So the algorithm can construct more effective connected dominating set (CDS) and balance the energy consumption among the nodes. |
