Analysis Study Of Time Synchronization Protocols In Wireless Sensor Networks

One of the main pervasive problems Wireless Sensor Networks(WSN) encounter is to maintain flawless communication sharing and cooperative processingbetweensensors via radio links to ensure a reliable treatment of information. Many applications based on these WSNs consider local clocks at each sensor node that need to be synchronized to a common notion of time. In this context, the majority of previous researches were focused on the study of protocols, and algorithms that address these issues in order to resolve synchronization problems. Previous fforts and empirical studies in wireless sensor network (WSN) proposed several solutions (algorithms). The focus of this this paperis to examine and evaluate the most important synchronization algorithms based on thepositionsof variousquantitative and qualitative synchronization protocolsfor energy-efficient information processing and routing in WSNs.
