摘要
介绍了一种应用于无线移动自组网的同步MAC协议FPRP(Five-Phase Reservation Protocol)并提出了I-FPRP(Improved Five-Phase Reservation Protocol)。协议采用竞争的方式为节点预约业务时隙,是一种分布式的MAC协议。协议通过5次握手解决了“隐藏终端”问题并有效减小了业务资源的冲突概率。通过仿真,对FPRP及I-FPRP的性能进行了分析和比较。
This paper introduces a synchronous MAC protocol FPRP and present I-FPRP used in wireless mobile Ad Hoc network. FPRP and I-FPRP are, based on a contention mechanism for the reservation of information slot, distributed MAC protocol. The protocol resolves ＂hidden terminal＂ problem and reduces effectively the collision probability of information resource by five-handshake, It also studies the performance of FPRP and I-FPRP via simulation.
