基于网格拓扑的无线传感器网络低能耗路由策略

摘要

According to energy consumption of wireless sensor networks (WSNs),a novel low energy consumption routing algorithms for WSNs is proposed.Based on grid topology structure,selection problem of relay node is solved.The problem can be transformed to 0 ～ 1 integer linear programming (ILP) and can obtain final relay selection.This algorithm is applied to real-time WSNs system,which gives low energy consumption routing strategy in the condition of meeting delay constraint.Simulation results show that the proposed algorithm can effectively reduce the energy consumption of WSNs,and extend the network lifetime.%针对无线传感器网络的能量消耗,提出了一种新型高效的低能耗路由算法.基于网格拓扑结构,主要解决了延迟约束下的中继节点选择问题.通过将问题转化为0～1整数线性规划,可以得到最终的中继选择.所研究的算法主要应用于实时无线传感器网络系统,它能够在满足延迟约束的条件下给出低能耗的路由策略.仿真结果表明:提出的算法能有效地减少无线传感器网络的能量消耗,延长网络寿命.
