Power Control Based on Non-cooperative Game in Wireless Sensor Networks

摘要

How to improve the energy utilization efficiency and prolong survival time of network has been an important issue in the field of wireless sensor network. In view of the energy-constrained situation in wireless sensor networks, we introduce game theory with non-cooperative game mode to optimize the network energy distribution. Regard the sensor nodes as rational participants in the decision-making process, nodes have mutual dependency and can make their own decisions according to their own situation. We select the most favorable strategy for the node after weighing of various power strategies through rigorous mathematical theory and model derivation. In this paper, we prove the existence of Nash equilibrium in the proposed algorithm. The experimental data and simulation show that the model provided in the paper can really optimize the resource distribution and prolong the lifetime of networks.
