无线传感器网络T-MAC协议的研究
摘要
自适应能量有效无线传感器网络T-MAC协议拥有一个自适应的休眠周期
动态地控制节点的活动状态时间来减少节点的空闲监听时间
有效地节约了节点的能量
同时还兼顾了网络的吞吐量。同时
由于无线传感器网络中不对称通信模式的存在
T-MAC协议存在早睡问题
很大程度上影响了网络的性能。根据中心极限定理
对T-MAC提出了一种改进设计
使其低负载时能耗更少
并一定程度上改善了早睡问题。
Abstract
The T-MAC protocol for wireless sensor networks (WSNs)has an adaptive duty cycle.Dynamically ending the active part time can reduce the amount of energy wasted on idle listening
while still maintains a reasonable throughput.For the asymmetric communication in WSNs
the early sleeping problem affects the property of WSNs.According to the theorem of probability
some improving designs are put forward which reduces the energy waste further more and solves the early sleeping problem.
