Implementation of Multi - hop Bidirectional Communication Link with Time - Synchronization on Miniature Test - bed of Underwater Acoustic Sensor Network

Abstract

energy efficiency. In Underwater Acoustic Sensor Network (UASN) it provides additional importance in terms of better utilization of the scarce acoustic bandwidth. For the convergence of various protocols in WSN and UASN such as Localization, Medium access control and Routing, nodes in the network are required to maintain time-synchronization. In this paper, we discuss the implementation details of multi-hop bidirectional communication link with time-synchronization on miniature test-bed of UASN. Successful implementation of this bidirectional link gives confidence and flexibility in developing higher layer protocols on the testbed and expanding the network topology.
