Abstract

Underwater sensor networks (UWSNs) has become one of the most interesting research area which opens the door of pleasing a lot of researchers to do the research in this field. There are so many issues in the underwater sensor networks. One is the most serious issue is void region that degrades the performance of the networks. It is the issue where a node doesn’t have any forwarder node to forward the packets to another node. Here the objective of this work is to avoid the void region. For the same purpose, this work proposes an algorithm named “An Energy Efficient Quality of Service (QoS) Based Void Avoidance Routing Technique”. The proposed work uses the two hop node information to avoid the problem of void region. This approach uses the Depth information, distance to next, holding time and residual energy as Quality of Service (QoS) parameters to find the best forwarder node to forward the data packet to the destination. The proposed algorithm has been implemented in MATLAB. Results show a better performance in terms of packet delivery ratio, energy tax and number of dead nodes as compared to Energy Efficient Void Avoidance Routing Scheme for Underwater Wireless Sensor Networks (E2RV).
