【摘要】 移动Ad Hoc 网(MANET)即早期军事研究中所称的移动分组无线网络,是以分组无线网技术为基础的互联的无线电台、计算机硬件和软件的集合。移动AdHoc 网技术由于可快速配置稳定有效的动态网络而被主要用于军事,消防,安全和救援等场合,其次还被用于工业和商业应用中,同时由于其组网灵活,费用低廉而被作为蜂窝移动通信网的补充技术。本文首先简要介绍了移动AdHoc 网的现状及发展前景,移动AdHoc 网的基本概念,网络特点,网络体系结构和面临的一系列问题。然后,基于移动AdHoc网的网络环境,对多种用于移动Ad Hoc 网络的路由协议进行了分析比较,采用AODV 路由协议作为网络层协议,并且分别用两种不同的方式改进了传统的AODV 路由算法,形成了CLAODV(Cross Layer AODV Routing Protocol)路由算法和ALAR(AODV Location_aided Routing Protocol)路由算法。本文采用OPNET 系统仿真工具搭建了移动AdHoc 网的仿真平台,在此平台的基础上,实现了AODV,CLAODV 和ALAR 路由算法。通过仿真比较传统的AODV 路由算法和改进的AODV 路由算法的网络性能,验证了CLAODV 和ALAR 算法的可行性,为实际系统的设计和规划提供了参考算法、参考模型和参考数据。更多还原

【Abstract】 The technology of Mobile Ad Hoc Networking (MANET) is somewhat synonymous with Mobile Packet Radio Networking (a term coined via during early military research in the 70’s and 80’s). It is the aggregation of hardware and software that include wireless transmitter-receivers and computers, which is based on the technology of Packet Radio Networking. The technology of Mobile Ad Hoc Networking is mainly uses in military/fire/safety/sescue because it can rapidly deploy survivable, efficient dynamic networking. Some application of MANET technology could include industrial and commercial applications and it can be operated as robust, inexpensive alternatives for cell-based mobile network infrastructures. The thesis first simply introduced the current situation and future development of Wireless AdHoc Networking, the basic conception of MANET, characteristics of the network, infrastructure of the network and a series of problems faced. And then, based on MANET environment, we compared many routing protocols used in MANET and select AODV routing protocol as the network layer protocol. We used two kinds of different ways separately to improved traditional AODV routing protocol and come into being CLAODV(Cross Layer AODV Routing Protocol)and ALAR(AODV Location_aided Routing Protocol)routing protocols. In this thesis, we put up simulation platform with OPNET, and realized CLAODV/ALAR routing protocol based on it. We compared network capability of taditional AODV routing protocol and advanced AODV routing protocol and validated the feasibility of CLAODV/ALAR algorithm. All these can provide consult algorithm, model and data for design and planning of the real system.更多还原
