Abstract:

Underwater Sensor Network (UWSN) is an emerging network exemplar which consists of underwater sensors that perform monitoring and resource exploration tasks over a given area. The UWSNs have high potential for monitoring the health of marine environments. The major drawbacks in UWSNs is the long propagation delay and draining of node’s energy, which reduces network lifetime. In order to overcome these snags, the combined localisation-synchronisation algorithm, which increases network lifetime by combining location and time synchronization information of nodes, and A* algorithm, which reduces the propagation delay by allowing packet transmission in multiple paths, has been coalesced. The proposed method collaboratively reduces propagation delay and increases network lifetime. It improves various QoS parameter such as throughput, end to end delay, packet delivery ratio and network lifetime.
