Resarch on Co-Synchronization Method and Channel Access Technology in Wireless Ad hoc Networks

Abstract

摘要 无线自组织网络(Adhoc)是一种无中心、多跳、分布式部署的无线网络,具有可快速、独立组网的特点。无线自组织网络的通信节点之间独立平等,无需固定设备支持,因此抗毁能力较强,可适应多种情况需求,具有广阔的应用前景。 无线自组织网络的信道接入(MediaAccessControl)协议掌管节点如何获取信道,对网络性能有着重大影响。和基于竞争的协议相比,基于时分的接入协议有着时延可控、无冲突传输等优势。但在提高基于时分的接入协议性能时,仍有两个难点需要解决:如何保证全网时间同步以及如何提高网络吞吐率。在基于时分的分布式协议中,时间同步是实现其他功能的重要前提,因此研究网络的同步速率具有重大...Abstract Wireless ad hoc is a distributed wireless multi-hop network with no-central node and distributed deployment, which has a rapit and dependent characteristic.The nodes in Ad hoc are equal and independent, without supporting from fixed equipments. As a result, they has a strong anti-damage ability and can satisfy the needs of many kinds of situations, which can make it has a broad applicati...学位:工学硕士院系专业:信息科学与技术学院_通信与信息系统学号:2332011115314
