摘要: 针对无线传感器网络的能量有效路由问题,以及能量消耗通常不满足所谓的“三角不等式”的特点,通过建立动态规划的能量消耗模型,将传感器网络的路由转化为矩阵和向量的运算问题,在此基础上提出一个适合传感器网络的矩阵乘路由算法。仿真结果表明,提出的算法能显著地降低路由的能量消耗,有效地延长网络的生存周期。

Abstract: Aiming to energy-efficient problem during routing in wireless sensor networks,and the characteristic of energy consuming,which can not meet with the relation of triangle-inequality,the paper transforms routing in the sensor network into the operation between matrix and vector,through the dynamic programming model of energy-consuming during routing in the sensor networks,and presents an algorithm of matrix multiplication routing,which fits the sensor networks effectively.Simulation results show that the proposed algorithm can reduce the energy-consuming during routing evidently,and prolong network lifetime effectively.
