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...

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.

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.
