A Power Control Algorithm Based on Game Theory in Ad Hoc Networks

Abstract

In mobile Ad hoc networks,power control method is an efficient way to improve the efficiency of energy used to transmit data packets.However,it will also produce negative influence on the network connectivity,delay and capacity.In this paper,proposed related energy control mechanisms for Ad hoc networks are analyzed.A power control model based on non-cooperative game theory is given.And a distributed non-cooperative game algorithm to power control for Ad hoc networks is presented to satisfy the requirement of maximum of network connectivity,maximum of network capacity and minimum network delay.And then the existing and uniqueness of Nash equilibrium for the algorithm is also proved in this paper.Simulation results show that the algorithm is efficient and has a good integrated performance.
