| 摘 要： | 为了提高无线传感网络的数据传输的稳定性和网络能量利用率，提出基于路径稳定和路径能量的改进AODV路由(An Improved AODV Routing based on Stability and Energy of Path, I-AODV-SE)。I-AODV-SE协议以按需距离矢量(Ad Hoc On-demand Distance Vector，AODV)为基础，对其路由决策机制进行改进。首先，I-AODV-SE协议先计算邻居变化率，再估计路径稳定性，然后，再计算路径能量，最后，基于路径稳定和路径能量计算路径权重，并择优选择权重小的路径传输数据。实验数据表明，提出的I-AODV-SE协议提升了网络生存时间和数据包传递率

| Abstract: | In order to improve the energy efficiency use and data transmission stability, An Improved AODV Routing based on Stability and Energy of Path (I-AODV-SE) is proposed in this paper, which is based on AODV, and it changed the routing decision. Firstly, I-AODV-SE computes the Neighbor Changed Ratio and stability of path. Secondly, it estimates the energy of path, then the weight of path is estimated, finally the path with minimum weight is used to transmit data. The simulation results show that I-AODV-SE can effectively improve the packet delivery ratio and prolong the network lifetime |
