摘要
针对ZigBee技术目前在能耗方面的缺陷,以及无线自组网络多跳特性导致每个节点不能感知到全网所有节点信息的问题等,对ZigBee无线传感网络的低功耗自组网进行研究.文章基于ZigBee的低功耗自组网技术,采用TPSN时间同步算法,为无线传感器网络在全网领域内提供时间同步,以解决无线自组网多跳的问题;采用低功耗时间同步算法DE-LEACH算法,以解决由TPSN同步时间算法带来的大量能耗的问题.实验证明DE-LEACH算法在传感网络中能量损耗更低,节点寿命更长.
In view of the fact that ZigBee technology is still flawed in energy consumption, the multihop characteristic of wireless ad hoc networks leads to the problem that each node cannot perceive all nodes information of the whole network. Therefore, it is necessary to reduce the power consumption of ZigBee wireless sensor networks. This paper presents a low power ad hoc network technology based on ZigBee, by using the TPSN time synchronization algorithm for wireless sensor network time synchronization within the whole network,to solve the problem of multi hop wireless ad hoc network ; and using the low power time synchronization algorithm DE-LEACH algorithm to solve the problem of a large number of energy consumption caused by TPSN time synchronization algorithm. Experimental results show that DE-LEACH algorithm has lower energy consumption and longer lifetime in sensor networks.
