MAC Protocol for Multimedia Sensor Network Based on Game Theory
Xiping Zhu · Jisuanji gongcheng · 2013
In wireless multimedia sensor networks,IEEE802.11e MediumAccess Control(MAC) protocol can not solve the fair access to channel between different services of each node.To solve this problem,this paper proposes MAC protocol for multimedia sensor network based on game theory.The main idea is that the channel contention process is modeled a dynamic game with incompletely information.Under different load conditons,the protocol improves the weight of the ordinary services and reduces the fairness between the different services.Simulation results show that this protocol can guarantee the Quality of Service(QoS) of multimedia services,make ordinary service,get more chance to access channel,and improve the average throughput of the networks.
