摘要
提出了一种基于能量感知的低占空比无线传感器网络路由算法(EALDR),用以解决低占空比无线传感器网络路由中的能量和延时的权衡问题。在做出路由决定时考虑MAC层的相关信息,对低占空比WSN的路由问题进行动态规划(DP)模型建模。仿真实验表明,该算法能有效减少延时,均衡节点能量。
The energy-aware low duty cycle routing algorithm(EALDR)is proposed to address the tradeoff between the energy and delay in the low duty cycle wireless sensor networks.Information of MAC layer is considered when routing decisions are made.The low duty cycle WSN routing problem is formulated through dynamic programming(DP).Simulation results indicate that EALDR can jointly optimize the energy and delay.
