Self Organizing Target- Reporting Sensor Node Selection for Underwater Wireless Sensor Network

Abstract

Under Water Sensor Networks UWSN are deployed to form distributed amorphous computing environments. While monitoring the ocean using UWSN, systematic approach has to be implemented inorder to forward data to the surface sinks. Forwarding of such data from ocean bottom to the surface sink is among the major challenges faced by UWSN. In this paper we propose a novel Self Organizing Target-Reporting Sensor Node Selection Algorithm TRSNSA, which makes the network an intelligent sentinel for monitoring Under Water UW environments. Furthermore, the residual energy of sensor nodes is also taken into account in order to improve the network lifetime. Our proposed self organizing algorithm when incorporated while routing can reduce the energy consumption of the network drastically. This algorithm is totally distributed. Each node takes a decision as to who amongst its neighbour those who have detected the target in their vicinity will participate in the routing algorithm. Our proposed technique avoids data packet flooding from source node to destination/ Surface station. Therefore energy of sensor nodes are conserved by avoiding broadcast of data packets to all the underwater sensor nodes.
