【摘要】 移动自组织网最初起源于军事,是一种特殊的对等通信系统,具有组网快速灵活、展开迅速、不依赖于通信基础设施、成本低、抗毁性高、生存能力强等特点,这些特性使得移动自组织网络在军事通信、抢险救灾等特殊场合具有广泛的应用前景。 移动自组织网络的无中心、多跳、无线广播、节点移动等特点使得如何使多个用户高效、合理地共享有限的无线信道资源,即如何解决媒质接入问题成为移动自组网中的关键技术之一。 本论文以国家863计划通信技术主题个人通信子专题重点项目:基于3G技术的移动自组织网络研究为基础,主要围绕移动自组织网络中支持可靠广播的的媒质接入控制技术展开研究,目的在于研究一种适合军事通信的MAC协议。 本文研究的FPRP不但可以为节点预约无冲突的广播信息时隙,而且控制部分开销相对较小:本文提出的I-TPRP协议在保证可靠广播的同时,简化了FPRP的帧结构,减小了控制部分的开销;由于FPRP和I-TPRP都是针对广播业务设计的,用它们传递点对点业务时造成资源的浪费,所以本文设计了一种满足军事通信中多种类型业务传递的MAC协议——F-RRP。更多还原

【Abstract】 Mobile Ad hoc networks is originate from military early. Ad-hoc is a peer-to-peer network for special application, and is characterized by flexible setup, fast-development, without necessity for the help or existence of any infrastructure, low cost and robust. These features have made a vast extent of application in such situations as the battlefield and disaster rescue.MANETs is character as a non-centralized, multi-hop, wireless broadcast, mobile node networks. How to make multiple users share a wireless channel efficiently and reasonably, i.e. how to solve the problem of media access, becomes one of the key technologies in MANETs.As a sub-project of the MANETs based on the 3G technology, this paper focuses on the research of medium access control technology that guarantees the reliable broadcast in Ad-hoc networks. Our goal is that researching a MAC protocol which fits in military communication.The FPRP researched in the paper can reserve non-collision broadcast information slot for node and its control cost is less. I-TPRP is brought in the thesis simplifies the frame structure of FPRP and reduces control cost while guarantees reliable broadcast. Because the FPRP and I-TPRP are designed for the broadcast traffic and the resource is wasted to transmit the point-to-point traffic using them, a MAC protocol E-RRP is designed for various kinds of traffic in military communication.更多还原
