Ad hoc网络路由协议仿真模型研究

The Study of Simulation Model for Routing Protocols in Ad Hoc Networks

对Adhoc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,是作者了解与学习路由协议性能的主要手段。目前的约束条件主要考虑无线传输模型、移动模型和能量模型;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以及连通度等内部属性上,而对这些约束条件和度量标准相互之间的关系进行系统地分析与研究,对仿真的流程进行程序化地处理,据了解目前还没有这方面的相关工作。论文基于作者以前的工作,提出了一种Adhoc网络路由协议的仿真模型,详细分析了Adhoc网络路由协议的仿真机制。

It＇s our main method to study routing protocols with simulation in different condition constrained and metrics.The current condition constrained are mainly focusing on the wireless radio model,mobility model and energy model and the metrics are the QoS factors such as throughput,delay,jitter,loss ratio and the external characteristics such as routing load or routing time and the inner property connectivity.However,the related works taking into account the relationship between them by the numbers and managing the simulation process as pipelining,to our knowledge,are very few.Based on our former works,this paper provides a simulation model for Ad hoc networks and analyses the simulation mechanism of routing protocols in detail.
