摘　　要：采用能量捕获技术的无线传感器网络节点,具有从环境捕获能量的能力,自带较少的能量就可以维持长时间的工作。实际应用中传感器网络大多分布在三维空间环境下,基于传统地理路由协议的研究,提出了一种适用于能量捕获无线传感网的三维地理机会路由算法。该算法首先将空间均匀划分为多个立方体,以确定合适的转发域,然后针对转发域内的各节点,根据剩余能量和传递成功率决定退避时间,最后将具有最小退避时间的节点作为转发节点。实验结果表明,该算法可以显著提高数据传递成功率,平衡网络节点的能耗,缩短数据包的平均发送时间,提高网络吞吐率。Using energy harvesting technology,the nodes in wireless sensor networks can gain energy from the environment,and keep working for a long time with a small battery capacity.Considering the WSNs mostly deployed in three-dimensional space in practical applications,based on the study of traditional geographic routing protocols,this paper proposed a three-dimensional geographic opportunistic routing algorithm for energy harvesting wireless sensor networks.First,the algorithm divides the space into cubes,and chooses an appropriate cube as next forward region.The nodes in the region calculate the back off time according to the residual energy and delivery rate.The node with shortest back off time becomes the transmission node.The simulation result shows that this algorithm can improve the data delivery rate effectively,balance the energy consuming of the nodes,reduce the average packet delivery time and make the throughput better.
