摘　　要：无线自组网在环境监测领域的应用已经十分普及,但受环境因素的影响,存在携带电量不足、节点能耗不均衡导致的网络生存时间较短等问题,并影响了监测效率。为了延长网络生存时间,提出一种基于改进GPSR多跳算法的WSN节点传输策略。建立了节点多跳概率模型,发现了特殊因子α。引入能量限制函数改进GPSR算法。采用NS2软件进行仿真实验。仿真结果表明:与LEACH算法和PEGASIS算法相比,提出的算法可以有效地均衡网络能量,延长网络生存时间。WSN has been widely used in the field of environmental monitoring.However,due to the influence of environmental factors,the monitoring efficiency is affected by the lack of electricity carried by WSN and the shorter network lifetime caused by the unbalanced energy consumption of nodes.In order to prolong the network lifetime,A node transmission strategy based on improved GPSR multi-hop algorithm is proposed for wireless sensor networks.The multi-hop probability model of nodes was established,and the special factors were found.The energy limiting function was introduced to improve the GPSR algorithm.NS2 software was used for simulation experiments.The simulation results show that compared with LEACH algorithm and PEGASIS algorithm,the proposed algorithm can effectively balance the network energy and prolong the network lifetime.
