Underwater Sensor Networks

Underwater Sensor Network (USN) is the developing and promising communication framework that enables a wide range of prominent applications like oceanographic data gathering, scientific ocean sampling, pollution and environmental monitoring, disaster prevention, and assisted navigation. The factors such as restricted bandwidth, high bit error rates and large propagation delay have posed several challenges in the design and deployment of USNs. The use of acoustic channels makes the problem more complex. The noise attenuation in deep water is a common issue that can be taken into consideration and novel layered multipath power control (LMPC) scheme tackles this issue.

NS2 Solution

  • The performance restrictions such as low reliability, low energy-efficiency, and high end-to-end packet delay in USN can be observed during the simulation using ns2.

  • Transmission power and data rate are controlled across the whole network

  • Minimizing energy consumption and simultaneous guarantee for other performance metrics in USN can be analyzed from results of simulation

  • Energy consumption is reduced by eliminating packet retransmission
