【摘要】 Ad Hoc网络是由一组带有无线收发装置的移动节点组成的一个无线移动通信网络，它不依赖于预设的基础设施而临时组建，网络的移动节点利用自身的无线收发设备交换信息，当相互之间不在通信范围内时，可以借助其他中间节点中继来实现通信。可广泛应用于军事、传感器网络、抢险救灾、应对突发事件等无法得到有线网络支持或临时需要通信的环境。本文首先简要介绍了Ad Hoc网络的发展与现状，分析了其特点和体系结构。然后对多种用于Ad Hoc网络的路由协议进行分析比较，得出采用AODV、DSR、TORA路由协议作为本理论的仿真路由协议。本文在群集智能的基础上，提出基于生存力发散和收敛的两种均匀分布理论模型。还对OPNET仿真软件的特点进行了简单介绍，并分别在节点采取匀速率和变速率、节点数目变化情况下，利用OPNET软件仿真得出何种理论模型、何种速率、多少节点数目采用何种路由最优实现，并为以后实际系统的设计与应用提供参考算法、参考模型和参考数据。更多还原

【Abstract】 The Ad Hoc Networks is a wireless mobile communication network with a set of mobile nodes with wireless sending and receiving device, which is set up temporarily without depending on the preset basic facilities. The mobile node of the network utilizes its own wireless sending and receiving device to exchange information. When each other of the nodes are not within the range of communication, they can realize communication with the aid of the relay of some middle nodes. The Ad Hoc Networks can be widely used in military affairs, sensor networks, rescue and relief work and accidents etc. which can not be served by the network or need communication temporarily.Here, the development of the Ad Hoc Networks and current situation is introduced and its characteristics and system structures are analyzed first. Then, many kinds of network route protocols which can be used in Ad Hoc Networks are compared and analyzed. Finally, it is determined that the simulating route protocols of this theory are AODV, DSR, TORA route protocols.On the basis of swarm Intelligence, two kinds of even distribution theory models are put forward, which are based on the divergent and convergent viability. A simple introduction has also been carried on to the characteristics of the OPNET software. On the case of the tests of uniform speed and variable speed and the changeable number on the nodes, it can be drawn the conclusion that what kind of the route can be realized optimumly by which kind of model, rate and how many nodes using OPNET software and offers the consulted arithmetic, models and datum for the later design and application of the real system.更多还原
