无线传感器网络中能量高效的时间同步算法

摘要

An algorithm called Energy-Efficient Time Synchronization (EETS) was proposed for energy constrained wireless sensor networks (WSNs). Some techniques, such as clock skew correction, local broadcast authentication and adaptive redundant messages were adopted in EETS to make the time synchronization in WSN energy-efficient and secure. The simulation results indicate that EETS satisfies these two goals.%针对能量受限的无线传感器网络,提出一种能量高效的时间同步算法(EETS).EETS采用时钟频偏校正、本地广播认证以及自适应冗余报文技术,使得无线传感器网络中的时间同步具备能量高效和安全的特性.仿真结果表明EETS满足了这两点目标.
