Time Synchronization for Mobile Wireless Sensor Network

Time Synchronization in Wireless Sensor Network

Time synchronization is a basic requirement for various applications in wireless sensor network, e.g., event detection, speeds estimating, environment monitoring, data aggregation, target tracking, scheduling and sensor nodes cooperation. Time synchronization is also helpful to save energy in WSN because it provides the possibility to set nodes into the sleeping mode. In wireless sensor network...

Time Synchronization in Wireless Sensor Network Applications

In most sensor network applications, events are time stamped with node’s local time. However, energy is highly constrained resource in sensor networks. The purpose of this paper is to present a timesynchronization algorithm for sensor networks that aims at reducing the computation and communication energy expended by the algorithm. We use MAC-layer time stamping and estimate the clock drift rat...

Fuzzy C Means Time Synchronization for Wireless Sensor Network

A new time synchronization algorithm for wireless sensor networks, named clustered consensus time synchronization (CCTS). To obtain faster convergence in the clock synchronization of node and better energy efficiency, the clustering technique is incorporated into the algorithm. The CCTS includes two parts: 1) intra cluster time synchronization and 2) inter cluster time synchronization.In the in...

SLTP: Scalable Lightweight Time Synchronization Protocol for Wireless Sensor Network

In wireless sensor networks, time synchronization is a critical problem. In this paper, we propose SLTP, a Scalable Lightweight Time-synchronization Protocol for wireless sensor networks. By using passive clustering and linear regression SLTP can reduce the energy consumption of network nodes and also decrease the overhead of creating and maintaining the clusters. Moreover SLTP uses linear regr...
