The ocean has been influencing the human race since ancient times. It provides food and sustenance items and plays vital role in weather system, economy and defence of the nations. More than half of the world population live within 150 km from coastline. The conventional exploring mechanism of the oceans involves sending/deploying a sampler in monitoring area of interest especially in the bottom of ocean which collects the required material and then return to surface. There is lack of real time monitoring and retrieving mechanism in case of failure or misconfiguration. Hence these limitations empower Underwater Wireless Sensor Network (UWSN) to become an appropriate candidate for the longstanding and reliable  monitoring and data gathering applications. However, UWSN faces lots of challenges due to; the dynamic underwater environment, changing network topology due to water current, and shipping and aquatic life activities. It incurs the substantial cost of deployment, maintenance, and device recovery to cope with unpredictable underwater circumstances. Water absorbs lots of RF (Radio Frequency) energy hence radio communication is not feasible in underwater environments. Hence the communication in underwater is accomplished using acoustic links. Acoustic communication is mainly in low frequency typically less than 30 KHz which limits the available bandwidth and hence lower data rates are observed in underwater communications. The instruments used in underwater devices are also vulnerable to tedious subaquatic challenges, for example, algae and salt accumulation on camera lens, decreasing the effectiveness of sensors and other important devices.
