Application Layer Time Synchronization Utilizing Symbol Timing Recovery In Wireless Sensor Networks

Abstract

Information sharing, scheduling and organization in a Wireless Sensor Network (WSN) is highly dependent upon achieving the same notion of time. Hence timing synchronization becomes a vital concern in most of the distributed wireless networks. Similarly, different layers of a network also need to synchronize among themselves for efficient performance and energy optimization. Bandwidth, energy consumption and storage capacity along with the high density of nodes are some of the practices limitations present in the WSNs. Symbol timing recovery (physical layer time synchronization) is used in this work for time synchronization at the application layer to achieve higher energy conservation.
