基于连通度的Ad hoc网络路由协议研究与仿真*

对Ad hoc网络各种路由协议进行仿真评估,分析它们在不同约束条件下不同度量的相对性能,是了解与学习路由协议性能的重要手段.目前的度量标准主要集中在吞吐量、延时、抖动、丢包率等QoS因子或路由负载、寻路时间等外部特性上,还没有以Ad hoc网络系统本身的连通度作为度量标准进行仿真,评价各种路由协议在不同试验条件下对于同一网络系统连通度的影响的相关研究.基于能量模型、节点密度、停留时间及移动速率四种约束条件对MANET提出的四种路由协议进行了关于网络连通度的仿真与评估,给出了这方面的初步结论.

Study and Simulation of Connectivity Based on Routing Protocols in Ad hoc Networks

It's main method to study routing protocols with simulation in different condition constrained and metrics.The current metrics are mainly focusing on the QoS factors such as throughput,delay,jitter,loss ratio and the external characteristics such as routing load or routing time.However,the related study using the connectivity as a metric to analysis the impact on network connectivity of diversified routing protocols in varying environment,are very few.The situation based on energy model,mobility model,node density,and draws some abecedarian conclusions were studied and simulated.
