Modeling and Simulation of Large Scale Wireless Sensor Networks Based on OPNET

无线传感器网络(Wireless Sensor Networks,WSN)是一种分布式传感网络,其特点为大规模、自组织、鲁棒性和动态性。论文首先对WSN节点协议栈进行了分析,然后使用OPNET对WSN节点模型、大规模网络模型、网络进程模型进行建模,最后使用该模型对贪婪周边无状态路由算法(Greedy Perimeter Stateless Routing,GPSR)进行了仿真,以图形化的方式对路由结果进行显示,对LCF路由算法下的WSN网络的负载和延时进行了仿真分析。

Wireless Sensor Networks（WSN）is a distributed sensor network,It is characterized by large scale,self-organization,robustness and dynamics,In this paper,the WSN node protocol stack is analyzed,and then the WSN node model,the large-scale network model and the network process model are modeled by OPNET. Finally,the model is used to analyze the greedy perimeter stateless routing（GPSR）. The simulation results show that the WSN network load and delay of LCF routing algorithm are simulated and analyzed in a graphical way.
