Energy Balanced Interference Aware Energy Efficient Depth Base Routing Protocol for UWSNs

Abstract

From few past years, researchers are attracted towards the unexplored region of earth due to is extreme usefulness and that region is water. As we know 70 % of earth surface is water and only 30 % is land that is already explored well. Due to the presence of useful resources in acoustic environment, researchers felt the need to explore the unexplored world of water. In order to explore the acoustic environment, many Underwater Wireless Sensor Network (UWSNs) routing protocols are already proposed. In UWSNs, small sensing nodes are deployed to monitor the desired area and mostly sinks (to gather information from nodes) are deployed on top of the water surface. But the sensing nodes in UWSNs posses limited battery for its operation. Due to harsh environmental conditions of acoustic life, it is impossible to replace or recharge the battery of nodes. Hence, energy is the main constraint in UWSNs. For this purpose, many energy efficient routing protocols are proposed, but it cannot completely solve the issue. In this paper we have proposed the energy balanced and interference avoidance technique due to which the network lifetime and through put increases. In EB-IAEEDBR we introduce the concept of energy balancing. The initial energy of all the nodes is divided into energy chunks, when the energy garde falls it informs its neighbor node about energy degradation by broadcasting the control packet. The node on receiving the control packet changes its transmission mode from multi hop to direct transmission mode as initially nodes are on multi-hop transmission mode. By this mechanism, energy consumption of node is evenly distributed in the entire network, results in better network lifetime, throughput and efficient energy consumption of nodes.
