无线传感器网络分布式同步协议
Distributed synchronization protocol for wireless sensor networks
摘要
Abstract
Distributed time synchronization and distributed data synchronization are proposed for the synchronization problem in wireless sensor networks . The former requires the cluster head network to execute local information exchange , and it adopts low‐pass filtering to remove the noise interference . The latter provides network‐wide data mean to nodes , and it requires the cluster head network to execute the proportion consistency algorithm , in which the number of nodes within a cluster is introduced during the iterative process . Experimental results show that the distributed time synchronization maintains anti‐noise performance , and that the algorithm converges fast in the earlier stage . Grid‐like network and random network experiments show that distributed time synchronization and distributed data synchronization have a low communication overhead , and their convergence rates are faster than that of general data synchronization .关键词
