移动Ad hoc网络由无线移动节点在没有任何现存的网络基础设施的情况下组成的自治系统,成为一个具有任意通信拓扑图模型的通信网络.由于网络节点的多跳性、有限的传输带宽、高速移动性、能量受限等特点,使路由协议成为Ad hoc网络设计的关键.主要介绍了Ad hoc网络的路由协议设计策略及分类原则,并对现有的具有代表性的路由协议性能进行了比较分析,为进一步研究提出新的课题.
A mobile Ad hoe network (MANET) is an autonomous system that mobile devices come together to form, as needed, without any necessary support from the exiting Interact infrastructure, the union of whJeh forms a eommunication network with arbitrary topology. Due to the limited transmission range of wireless network interfaces, multiple holm are needed. MANETs are characterized by multiple hops, limited bandwidth, high mobility and limited power resource, so muting becomes a key technology in Ad hoc network. This paper mainly introduces the design strategy and clarification principle for Ad hoe network routing and compares performances of existing typical routing protocols.
