A Power Control Algorithm Based on Non-cooperative Game for Wireless CDMA Sensor Networks

How to improve energy efficiency of WSNs(Wireless Sensor Network) is an important problem on the design of WSNs , for the demand of Multi-Services , a non-cooperative game power control model is proposed based on the WSNs model of CDMA, the existence and uniqueness of Nash Equilibrium in the game are proved. Then a distributed power control algorithm is proposed based on the game model. Simulation results show, because take into account the factor of node residual energy on the design of the game model, the algorithm can effectively reduce total transmitting power of nodes, save nodes energy and prolong network lifetime efficiently.
