Abstract: The node mobility models have an important influence on the topology of Mobile Ad hoc Networks(MANET), thus only the studies that under reasonable node mobility model are trusty. This paper generates the entity model, group model and area restricted model through expanding the NS2 and analyzes them in physical aspect and routing aspect. It shows that different mobility models have obvious different affection on the routing protocol. It is very useful in evaluating and studying routing protocol in MANET.

Key words: Mobile Ad hoc Networks(MANET), node mobility models, routing protocol, network simulation

摘要： 移动自组网(MANET)节点移动特性对网络拓扑结构有重要影响，在合理的节点移动模型下对网络性能的评估才真实可靠。通过对网络仿真软件NS2进行拓展，实现个体、群体和具有地域限制的节点移动模型，提出物理链路和路由协议2个层面的评估准则，给出不同类节点模型对路由协议性能的影响程度。对研究和评估MANET的路由协议有重要的参考价值。
