摘要: IEEE802.11e媒体接入控制(MAC)协议不能较好地满足无线多媒体传感器网络不同类型业务节点间的公平性要求。为解决该问题,提出一种基于博弈论的无线多媒体传感器网络MAC协议。将节点间的信道竞争过程建模为非完全信息动态博弈,在不同的负载情况下,通过改变普通业务的权重提高不同业务间的公平性。仿真结果表明,该协议能在保证多媒体业务服务质量的同时,增加普通业务数据流接入信道的机率,提高整个网络的平均吞吐量。

Abstract: In wireless multimedia sensor networks, IEEE802.11e Medium Access 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.

Key words: wireless multimedia sensor network, Medium Access Control(MAC), IEEE802.11e protocol, game theory, Quality of Service(QoS)
