摘要
能量均衡技术一直是无线自组织网络的热点研究领域。在深入研究网络信息传输特性的基础上,提出了一种基于移动—能量代价函数的无线自组织网络路由策略,并用于网络信息传输。首先,本文考虑节点连通性、能量均衡性,提出了一种节点移动策略;然后,以传输路径节点集合中的瓶颈节点剩余能量、传输链路数量作为准则,建立以网络节点为对象的能量代价函数。基于移动—能量代价函数的路由策略从链路层的决策转移到节点层的决策。最后,采用MATLAB数值仿真该路由策略的性能,结果显示:本文提出的移动—能量代价函数的路由策略既保持了原有路由优化的精度,延迟网络瓶颈节点能量下降速度,提高网络生存时间。
The energy balance technology is a hot research field of the wireless selforganizing network.After the further study of the network information transmission characteristics,a kind of wireless selforganized network routing strategy used for network information transmission is proposed based on mobile-energy cost function.At first,considering the node connectivity and energy balance,a node mobile strategy is carried out;then a energy cost function is designed With residual energy of transmission path bottleneck nodes and transmission link number as criterion,and the routing strategy is determined in node layer instead of link layer;at last,the numerical simulation is performed on MATLAB,the result shows the routing strategy proposed keep the original optimal routing precision,delay the network bottleneck node energy falling speed and improve the network survival time.
