Robust Opportunistic Routing Solutions for under water Sensor Networks

The Underwater Sensor Networks (UWSNs) consists of several sensor nodes along the ability of sensing the underwater information, processing, & transmitting the sensed data towards the remote station through the underwater communication protocols. The key challenges of UWSNs related to the low bandwidth, high propagation delay, & more energy consumption. Most of such challenges have been concerning along the design of routing protocol for under water data forwarding. Under this paper, novel opportunistic routing protocols proposed to reliable data forwarding under UW-ASNs along aim of improving the Quality of Service (QoS) performance & energy efficiency. The problem of energy-efficient data forwarding has been solved through utilization the optimum opportunistic route construction algorithm utilization the Advanced Particle Swarm Optimization (APSO) & local properties of sensor nodes. The proposed protocol called like Opportunistic under water routing utilization APSO (OUR-APSO). Under OUR-APSO, the functionality of relay node evaluation designed utilization the local information such like Node Degree Probability (NDP) along ratio of Energy Decreased & Packet Delivery Probability to connect next forwarder node to enhance the reliability of the network. NDP means the number of neighbours to forward incoming traffic. If there have been only a few relay nodes & all having the low ECR & PDP, then it can lead to network failure. Thus considering the nodes, the next relay node selected basis on outcome probability utilization for ECR, PDP & NDP properties of all neighbouring sensor nodes. The simulation result proves the efficiency of proposed protocol.
