| 英文摘要 |
| In this paper, game theory is applied to the WSN power control to reduce the energy consumption of the point
transmission and prolong the lifetime of the network. The utility function is constructed by considering the residual energy
and the transmitted power of the node. The remaining energy larger node is as the next hop node, which connects other
nodes and takes more transmission tasks. In the communication process, the nodes take power control game algorithm as
strategy and constantly adjust their strategies to improve the accuracy of information transmission. Nash equilibrium is
proved to exist in the algorithm. Simulation results show that this algorithm can realize the purpose of reducing the energy
consumption of wireless sensor network through the control of node transmission power, calculating the optimal transmit
power faster, and getting the higher signal interference ratio compared with traditional distributed power control algorithm. |
