WLAN中非完全合作博弈策略的MAC协议

IEEE802.11e机制中采用重设竞争窗口的机制提高无线局域网的QoS,但是,在高竞争的情况下低优先级的业务资源却被高优先级业务耗尽,导致传输不公平,低优先级业务吞吐量低,针对此问题,在EDCA的基础上提出在不同节点之间使用非完全合作博弈理论,竞争与合作相结合的策略,在不影响高优先级业务的QoS前提下,保证低优先级的业务,提高传输的公平性.仿真结果表明,与802.11eEDCA相比,该策略有效地实现了吞吐量与公平性的折中.

The MAC Protocol Based on Incomplete Cooperation Game Theory in WLAN

The mechanism of IEEE802.11e improved QoS of WLAN based on the mechanism of reset competition window,while in the condition of high competition,the resources of low priority business was run out by high priority business,then transmission is not fair,so low priority business has low throughput.According to this problem,proposed incomplete cooperation game theory that competition and cooperation complemented each other between different QSTAS based on EDCA,ensure low priority business without affected QoS of the higher priority business,improve the fairness of transmission.The simulation results show that,compared with 802.11e EDCA,this strategy compromised throughput and fairness.
