Minimization of Energy Hole in Under Water Sensor Networks (UWSNs)
Abstract: The major difference between underwater sensor network and terrestrial sensor network is use of acoustic signals as communication medium rather than radio signals. The main reason behind this is the poor performance of radio signal in water. UWSNs have some distinct characteristics which makes them more research oriented like large propagation delay, high error rate, low bandwidth and limited energy. UWSNs have their application in the field of oceanographic, data collection, pollution monitoring, off shore exploration, disaster prevention, assisted navigation, tactical surveillance etc. In UWSNs the main advantages of protocol, design is to a reliable and effective data transmission from source to destination. Among those energy efficiency plays an important role in underwater communication. The main energy sources of UWSNs are batteries, which are very difficult to replace frequently. Two popular underwater protocols are DBR and EEDBR. DBR is one of the popular routing techniques, which don't use the full dimensional location information. In this research work, we use an efficient area localization scheme for UWSNs to minimize the energy hole created. Rather than finding the exact sensor position, this technique will estimate the position of every sensor node within certain area. In addition to that we introduced a RF based location finding and multilevel power transmission scheme. Simulation results shows that our proposed scheme produces better result than its counter parts.
