摘　　要：结合实际的移动adhoc组网研究,针对以往MANET路由协议性能评价中没有考虑网络连通性的问题,引入了反映网络节点通信能力和网络连通性的网络覆盖密度概念,并进行了基于拓扑的MANET典型路由协议性能与网络覆盖密度相关性的研究.仿真结果分析表明,基于拓扑的adhoc路由协议包递送率随着网络密度的增加而增加,并与其构成S曲线.通过最低网络覆盖密度的定义,为实际的adhoc组网中各种路由协议的适用条件提供了明确的评判依据.In most existing performance evaluations of ad hoc routing protocols, connectivity is not considered properly. To solve this problem, a new concept of network coverage density is adopted, which reflects communication ability of nodes and connectivity of ad hoc network. Based on this, a research is conducted on the relationship between performance of topology-based MANET routing protocols and network coverage density. Simulation results show that, packet delivery of routing protocol heightens with the increase of network coverage density, and they form an S curve. Through the definition of minimal network coverage density, a judgment criterion for applicability of routing protocol is provided in the process of ad hoc networking.
