无线传感器网络时间同步算法误差分析

Error Analysis of Time Synchronous Mechanism in Wireless Sensor Network

时间同步是无线传感器网络应用的重要组成部分,传感器数据融合、传感器节点自身定位等都要求节点间的时钟保持同步。本文以时间同步的基本原为出发点分析了基于发送者-接收者交互模型的时间同步过程及其误差。为无线传感器网络间同步机制设计和分析提供一定的理论依据。

Time synchronous mechanism is a very important part in wireless sensor network, time synchronous is necessary in data integration and self-position in sensors. The sender-receiver model time synchronous process and its error are studied on the base of basic time synchronous principle. It provides some important basis for designing time synchronous algorithm and analysis in wireless sensor network.
