摘要:

提出一种增强型无线传感器网络的小道消息(gossip)时间同步算法,利用无线信道的广播特性来提高同步性能. 传统的gossip同步算法是点对点的通信方式,增强型gossip同步算法是点对多点的通信方式. 理论分析和计算机仿真均表明此方法可以提高无线传感器网络时间同步的收敛速度,并且可以降低网络能耗.

关键词: 时间同步, gossip算法, 无线传感器网络

Abstract:

An enhanced gossip time synchronization algorithm for wireless sensor networks was proposed to improve the performance of synchronization by integrating the broadcasting characteristics of wireless channel. The communication mode of traditional gossip algorithm is peer to peer, while the mode of the proposed algorithm is peer-to-multi. Both analysis and simulation confirm the effectiveness of the proposed algorithm in expediting the convergence rate and reducing the energy consumption.

Key words: time synchronization, gossip algorithm, wireless sensor networks
