Abstract:
The Underwater wireless remote sensors convey messages in a range, where there is no possible human intervention. It is difficult to replace the battery and save energy in an acoustic environment, even solar energy cannot be used to energize batteries. These sensors are required to work for a long period of time, but they have constrained energy limitation. Underwater Wireless Sensor Networks (UWSN) have unpleasant surrounding which leads to high energy constraints, low bandwidth, decreased throughput, propagation delay. The speed of the sound also varies, which results in the specific loss. Combined attenuation and noise occurrence result in a typical power spectral density which leads in a decline of 18 dB in the duration of ten years. While packets are being forwarded, the energy consumption must be less or balanced, else energy holes are created. In such cases: the energy efficiency, lifetime and throughput are expanded. In this poster, we have summarized energy based routing protocols with bandwidth efficient techniques.
