Abstract

Objectives: To design and develop the Multi-layer Multipath Data Forwarding Routing (M2DFR) protocol for Underwater Wireless Sensor Network which controls the water depth, node mobility and can enhance the overall performance. Method/Analysis: M2DFR is based on three phases, one is design of architecture under which the deployment of the nodes are shown, second is the initialization phase which develops the multipath route selection mechanism between seabed source nodes to ordinary nodes which are deployed in the lower depth to upper layer, Acoustic Powerful Nodes (APNs) deployed in upper depth in fixed way in layers to surface sink nodes which are deployed on water surface, the route selection for multipath is based on RREQ/RREP through Weight Calculation Mechanism (WCM). Third phase focuses the data forwarding phase under which the shortest WCM is selected and from this route packets are forwarded from source nodes to sink nodes. Findings: Most of the existing protocols are unable to overcome the problem of water depth controlling, uncontrolled node mobility. Applications/Improvements: M2DFR is designed to extract the information from the bottom of the sea with its applications like: gold, oil/gas and minerals. The improved performance of M2DFR is measured with CBE2R and EMGGR.
