低WSN服务能耗的MAC协议实现

Implementation of MAC protocol with low WSN service energy consumption

为解决WSN服务能耗和服务质量问题,提出了一种无线传感器网络介质访问控制协议WTRP-S,分析比较了WTRP-S,WTRP和IEEE802.15.4MAC的性能,建立了节点启动调度模型。仿真结果表明:在数据业务大的网络中,该协议既能保证服务质量,在节点关闭通信模块中能够节省更多能量,使得整体能耗降低,WTRP-S适用于能量受限的无线传感器网络。

A MAC protocol called WTRP-S is presented to reduce the energy consumption and improve the QoS of WSN service.Simulation and analysis show that compared with WTRP and IEEE802.15.4 protocols,WTRP-S is suitable for energy constrained wireless sensor networks.In data sensitive network,the protocol can guarantee the QoS of network.If the communication module is closed,the protocol can save more energy,decreasing the overall energy consumption.
