IMPROVISED OPPORTUNISTIC ROUTING FOR UNDERWATER WIRELESS SENSOR NETWORKS

Abstract In the recent years, Underwater Wireless Sensor Networks (UWSNs) has attracted the wireless research communities. Resource Discovery (RD) and Ocean monitoring are the two concepts explored by the researchers. In order to achieve successful packet delivery ratio, the constraints in acoustic communication channel has to be explored. This paper concentrates over devising opportunistic routing protocols using acoustic communication channel.Improved opportunistic routing protocols takes advantage of distributed beaconing, constructs the adjacency graph at each hop and selects a forwarding set that holds the best trade-off between reliability and energy efficiency. The unique feature of an improved opportunistic routing is the selection of accurate next-hop forwarder nodes which trade-off the node configuration issue. Our simulation result shows that improved opportunistic routing works better than prior routing protocols, GOR in terms of reduced packet loss, energy consumption, endto- end delay and propagation deviation factor.
