一种Ad Hoc网络的MAC层分层节量控制机制

An MAC Stratified Energy Control Mechanism on Ad Hoc Network

通常采用电池作为Ad Hoc网络移动节点,往往因为能源的利用率问题缩短网络的运行寿命。在IEEE802.11PSM传统分层思想基础上,根据多跳节点活动概率周期、链路状态、跨层服务等众多参数,提出了一种三层节能控制机制。通过时隙分析,与IEEE 802.11 PSM的比较,多层节能机制大幅降低了能耗,还减少了数据的平均端到端时延。

Ad Hoc networks mobile nodes commonly used batteries to provide energy. Therefore, all nodes must maximize energy efficiency and reduce energy consumption, to extend the life of the network. Based on the traditional hierarchical thinking, a new three - tier energy control mechanisms is proposed. Compared IEEE 802.11 PSM with the multi - tier mechanism, the latter not only substantially reduce the energy consumption of energy,but also reduce the average end- to - end delay of data.
