Efficient Noise Aware Level Based Routing Protocol for UWSNs

Abstract

This is the age of scientific revolution and invention. With the passing of time science has been experienced with new technology & research area. Underwater sensor network is one the challenging and interesting research arenas that opens the door of pleasing a lot of researcher in studying the field. In many applications, underwater nodes are energy constrained as well as node is mobile in water environment due to water current; and therefore, develop a scalable, robust and energy-efficient protocol is very challenging and sometimes it is a difficult task. In spite of this constrained manner, researcher is developed several routing protocol but those are lost their appeal with the time. This is the demand of age to provide an energy-efficient and scalable robust routing protocol. In this thesis we propose a novel routing protocol named level based routing (LBR) protocol, aiming to provide robust, scalable and energy efficient routing. LBRP is essentially a level-based routing approach. No state information is required on the sensor nodes and only a small fraction of the nodes is involved in routing. LBRP also promises the best use of total energy consumption and ensures packet transmission is more reliable in compare to other routing protocol. The proposed routing protocol takes into account residual energy, level and distance from the forwarding node to the sink node to guide a packet from source to the destination node. The forwarding decision is taken by level of the forwarding node and applying multicasting technique. We use level of forwarding node, residual energy and distance from the forwarding node to the sending node as evidence in Multicasting technique. Simulation has been experienced both in noisy and noiseless environment and executed to endorse better performance of the proposed protocol.
