传感器网络中实现传输功率均衡的移动控制算法

在传感器网络中， 为了延长网络寿命和增加网络容量， 需要引入新的方法减小传输功率的差异， 弥补传统拓扑控制算法的局限性． 提出了PMST-P和PMST-UV两种移动控制算法， 在保证网络连通性的前提下， 根据网络分割区域图确定增补链路和移动节点， 并令移动节点按照一定的移动方式移动到增补链路处， 从而构造出一个传输功率较为均匀的网络拓扑． 结果表明，两种算法都能使最大通信半径减小到临界通信半径之下， 显著提高了拓扑控制的性能， 且PMST-UV算法与PMST-P算法相比， 移动距离只有后者的50％左右， 移动节点比率减小0.4左右， 因而具有更好的性能．

Movement control algorithms for realizing the balance of transmission power for sensor networks

In wireless sensor networks,in order to prolong network life time and improve network capacity,it is necessary to introduce a new technique to reduce the difference of transmission power,which can not be solved by traditional topology control algorithms.Two movement control algorithms,PMST-P and PMST-UV,are proposed in this paper.With the network connectivity unchanged,a topology with the distribution of transmission power being more uniform can be constructed by determining additional links and moving node...
