| 摘 要： | 如何在提供能量高效数据通信的同时满足必要的延迟需求,是无线传感器网络MAC协议面临的一大挑战。本文提出一种基于梯型休眠调度的MAC协议——LP-MAC,通过安排传输路径上的节点连续转发数据从而消除休眠延时;采用冲突避免机制和基于链路计数器的临时唤醒机制,减少兄弟节点间冲突并增加节点休眠时间,进一步提高协议能量效率。理论分析和模拟实验表明,LP-MAC协议既具有低能耗的协议特性,也能保证较低的稳定的端到端延时。

| Abstract: | How to provide energy-efficient communication without necessarily sacrificing application-specific latency performance is a key challenge confronting wireless sensor network MAC protocols.In this paper,LP-MAC,a MAC protocol based on ladder pattern wakeup scheduling is proposed.By arranging the nodes in a multi-hop path to forward data continuously,the wakeup delay is eliminated;by the conflict avoidance scheme and the temporary wakeup mechanism based on link counters,the conflicts between the sibling nodes ... |
