Abstract: In Underwater Wireless Sensor Networks (UWSNs) energy, throughput are wide are of interest. These sensor networks make it possible in real time monitoring of the underwater environment. Major challenges that ar4e faced in such environment are low battery power, high bit error rates, low bandwidth availability etc. This paper mainly examines these challenges and possible solutions to overcome the problem by using a cluster formation among the nodes which communicate with a mobile sink. Our work mainly focuses the formation of cluster and path discovery of the cluster by the mobile sink. Finally, by using this strategy we prove that the energy used by sensor networks is lesser than other algorithms.
