摘要

基于快速、有效竞争预约接入、无冲突轮询传输的思想和带冲突预防的冲突分解策略

本文提出了适于移动Ad Hoc网络的公平按需多址接入(FODA)协议.该协议在分群结构的基础上

利用公平冲突预防算法预约信道资源获得轮询服务

从而完全消除了载波侦听方式下多跳无线网络业务传输中的隐藏终端和暴露终端问题.另外

公平冲突预防算法解决了节点竞争接入时的冲突问题和不公平现象.最后

仿真结果表明

与带冲突避免的载波侦听多址接入(CSMA/CA)和轮询协议相比

FODA协议可以提供较高的信道吞吐量、较低的平均消息丢弃率和平均消息时延.

Abstract

Based on the concept of contention reservation for polling transmission and collision prevention strategy for collision resolution

a fair on-demand access (FODA) protocol for mobile ad hoc networks (MANET) is proposed.In the protocol

a clustering network architecture acquired by clustering algorithm and reserving channel resources by fair collision prevention (FCP) algorithm to obtain polling service are adopted

so that the hidden terminals (HT) and exposed terminals (ET) problems existed in traffic transmission due to carrier sensing

multihop architecture and wireless transmission method can be completely eliminated.In addition

the FCP algorithm can also completely resolve unfair phenomena and access collisions in the present of contention access of newly active nodes.Finally

performance comparison of the FODA protocol with carrier sense multiple access with collision avoidance (CSMA/CA) and polling protocols are presented and simulation results show that the proposed protocol can achieve higher throughput

lower average message dropping rate and delay.
