无线传感器网络能量有效时间同步算法

In wireless sensor networks, energy efficiency is an important standard for evaluating the effectiveness of the time synchronization protocols. Hence, energy should be conserved as much as possible provided that algorithm can achieve a certain accuracy. In this paper, we propose an energy efficient time synchronization algorithm in which each layer of the network can be synchronized merely by receiving broadcast messages rather than relying on two-way message exchange. Simulation result shows that our improved strategy reduced the energy consumption and prolonged the lifetime of network compared with TPSN
