Exploiting Localization Capability and Packet Transfer at Intermediate Nodes for Underwater Sensor Networks using Simulations

Underwater wireless sensor relies on the vantage point in networking for data transfer to sink, which is being positioned at the top surface. The sensor nodes subjected for data transfer are being affected due to mobility which hinders multi-hop communication. Thus localization of the sensor node to provide measurement and data transfer post deployment varies. Thus subsequent investigation has to be made continuously for routes to enable location coordinates. The purpose of this work is to consider the localization within a sensing area and underlying routes for data transfer associated to sink. Underwater Localization and Packet Transfer (ULPT) has been proposed to estimate the sensing area maps, connectivity holes in data transfer with in upper hemispherical transmission range at appropriate time stamps. Simulation of the proposed protocol with aquasim patch in network simulator 2 captures the experimental condition analogous to underwater networks.
