Abstract

Objectives: Under-Water Sensor Network (UWSN) has many potential applications. For these applications it is necessary to have efficient and reliable communication. For efficient communication we need to develop efficient networking solutions to overcome the underwater environment challenges. Methods: To develop efficient solutions for networking we require to understand the potential applications for the underwater sensor network it is also necessary to understand the limitations of the environment. It is also essential to understand different architectures that are there in UWSN. Using these information's, we have designed a network with 6 nodes and simulated it using Aquasim software. We have selected one specific MAC layer and network layer protocol. For this we have simulated for the Packet Delivery Ratio (PDR), throughput and energy consumption parameters. Findings: Paper talks about the 2D UWSN architecture, the challenges in the implementation of UWSN, the MAC and Network layer used. We can anticipate the general energy consumption, through put and PDR for this combination of Radio Multiple ACcess (RMAC) and Vector-Based Forwarding (VBF) protocols. This simulation shows us that this combination follows the required trend and they are the suitable protocols to be used in UWSN implementations. Improvements: Applications of UWSN are fast gaining popularity to make it possible to monitor the ocean, surveillance of deep sea, various entities tracking of aquatic environment, etc. For all these applications the energy efficiency is ansignificant factor for communication. Comparative studies show that R-MAC is the most energy efficient MAC layer protocol and VBF has better PDR and throughput compared to other network layer protocols.
