| 摘 要： | 提出了一种新的适用于Ad hoc网络的媒体接入控制算法,该算法通过五次握手预约调度资源,利用节点底层的多包接收(MPR)能力,保证高概率的接入和提高并行传输率,从而提高网络吞吐率。对算法进行了理论分析和仿真,分析结果表明与FPRP相比,有效地提高了Ad hoc网络的吞吐率。

| Abstract: | This paper proposed a new medium access control algorithm.This algorithm utilized five-way handshake for reserving resource and the information of node's multi-packet reception(MPR) ability,the maximal probability to access channel was determined,and the parallel transmission was increased thereby so as to improve the throughput performance of the networks.Then analyzed the performance of algorithm.The results show that the Ad hoc network throughput is efficiently improved,compared with the FPRP. |
