Energy analysis on localization free routing protocols in UWSNs

Abstract

The challenges faced in underwater communication systems are limited bandwidth, Energy consumption rate, larger propagation delay time, End-End Delay (E-ED), 3D topology, media access control, routing, resource utilization and power constraints. These issues and challenges are solved by means of deploying the energy efficient protocol. The protocol can either be localization-based protocol or localization free protocol. In this paper, review of localization free protocols were discussed and reviewed with reference to environmental factors, data transmission rate, transmission efficiency, energy consumption rate, E-ED and propagation delay. The review analysis gives the pros and cons to give rise to the new directions of research for future improvements in Underwater Wireless Sensor Networks (UWSNs). This manuscript propose a survey on localization free protocol according to the problem addressed or the major parameter considered during routing in UWSNs. Unlike the existing survey, the present survey focuses on present state and art of routing protocols, in terms of routing strategy issues addressed. The solutions of energy efficient protocol is arrived by highlighting the pros of each protocols. The description of routing strategy for each protocol is presented to understand its operation in an understandable form. The cons of each protocol is taken into consideration for further investigation and to arrive the best protocol. The presented routing strategy, pros and cons provide open challenges and research directions for future investigation.
