Two third of the earth is covered with water and there has been a growing interest in monitoring underwater medium for scientific exploration and attack protection. Underwater sensor nodes will find application in ocean-graphic data collection, pollution monitoring, disaster prevention and tactical surveillance application. Underwater network consist of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring task over a given area. On the other hand the terrestrial wireless networks are the networks without cable and are very easy to install and offer portability and convenience which other network solutions do not offer.
