Optimized MAC Protocols in Wireless Sensor Networks Based on Game Theoretic

The channel contention process is modeled as a dynamic game with incomplete information,and Nash Equilibrium(NE)of the game is obtained.Based on S-Medium Access Control(MAC)protocol for Wireless Sensor Networks(WSN),the IIDG-MAC protocol is proposed by using NE.Simulation results indicate that compared with S-MAC,using IIDG-MAC increases the successful transmission rate of packets,decreases energy consumption for retransmitting packets,delay and bit-drop-rate,and increases the system throughput.
