摘要

本文基于有效竞争预约接入、无冲突轮询传输的思想提出了在多跳分布式无线网络中支持节点移动性和多跳网络结构的依据用户妥善安排的多址接入(UPMA)协议.该协议能够保证发送节点快速接入信道

从而大大提高信道的使用效率.用仿真方法研究了多跳分布式无线网络中采用该协议时的网络性能.结果表明

UPMA协议可以提供较高的通过量、较低的平均分组时延和较小的平均分组丢失率.

Abstract

Based on the idea of contention reservation access and polling transmission

User-dependent Perfect-scheduling Multiple Access (UPMA) protocol is presented

which supports both node mobility and multi-hop network architecture.It improves channel utilization greatly and guarantees that a node accesses the channel rapidly.By adopting the protocol in multi-hop wireless ad hoc network

the network performance of Poisson data traffic is simulated and the related results are given

which show that the UPMA protocol has high throughput

low packet transmission delay and small packet dropping probability.
