基于Ad hoc网络路由策略的研究与仿真
Research and Simulation of Routing strategy based on Ad hoc network
Abstract
Adhoc网络是由一组带有无线收发装置的移动节点构成，这种网络不依赖于地面基站或其它基础设施，节点之间通过多跳转发的方式通信，具有快速组网，抗摧毁等优点，特别适用于突击抢险、协调救灾、军事作战等。路由策略作为Adhoc网络的核心内容之一，对其性能有着重大的影响，而路由的度量又是路由选路的核心。本文对一种具有自动重传机制的TDMA自组网的路由问题展开研究。 论文仔细地分析了一种带有自动重传机制的TDMA自组网的多跳传输过程，将影响链路质量的各因素归一化为链路的时延，并给出总平均时延和接收平均时延两种基于多跳（端对端）时延的路由度量。论文对以上两个路由度量指标进行数学推导，分别得到它们的闭合表达... Ad hoc network is composed by a group of mobile nodes with wireless transceiver, which does not rely on the ground station or other infrastructure. Nodes in Ad hoc network communicate with each other by multi-hop forwarding and this network has the advantages of rapid networking, anti-destroy, especially suitable for assault and rescue, disaster relief and military coordination. As one of the core...
