结合冰凌测报无线传感器网络中传感器节点能量受限、节点随着冰凌的产生与流动会出现在河道断面局部观测区域的冰凌测报无线传感器网络拓扑结构不断变化这一特性,提出了对贪婪周边无状态路由协议GPSR的改进策略GFSRI(GPSR-Improved),改进算法中采用图论模型,借助网络模拟器NS2(Network Simulator 2),对GPSR算法以及改进的路由策略GPSRI进行了模拟仿真实验,对路由算法中涉及到的关键参数的相关实验数据进行了处理分析.模拟仿真实验及评估结果表明,GPSRI在数据包转发的路由跳数、源和目的节点间端到端的传输时延方面与GPSR相比有较大的性能改进.
Combined with the fact that the sensor node energy is limited in the WSN wireless sensor network, with the characteristics of ice topography changes and the topological structure of the WSN wireless sensor network changing with the appearance and flow of ice appear in the local observation area of the river channel cross section, In the improved algorithm, Graph Theory Model (GFSRI) is adopted as an improved strategy of GPSR. The simulations of GPSR algorithm and GPSRI with improved routing strategy are carried out by using network simulator (NS2). The routing algorithm Related to the key parameters involved in the experimental data processing analysis.The simulation results show that, GPSRI in the packet forwarding routing hops, source and destination nodes end to end transmission delay compared with the GPSR Greater performance improvement.
