In this paper, we present a complete Geocasting solution for underwater sensor networks. The model named Routing and Multicast Tree based Geocasting (RMTG) [1,2] has been designed for underwater sensor networks. In our previous work [1], we proposed and simulated the RMTG model in terms of routing, route maintenance, link stability and data dispersion inside the geocast region in static as well as in mobile network conditions. In [3] we provided the theoretical improvement over the RMTG in terms of Geocasting for underwater sensor network by providing solutions for hole/void area detection inside the geocast region and a solution to cover the scattered nodes in the geocast region for guaranteed message delivery by means of boundary routing (that is routing by traversing all the faces of a particular geocast region). Here, the work in [3] has been enhanced, the model is named as Routing and Multicast Tree based Geocasting with Hole Detection (RMTG-HD). A detailed analysis and performance evaluation of the proposed model has also been provided. The simulation results show that the proposed model provides an efficient distribution of data in the geocast region in terms of packet delivery ratio, boundary routing delay, hole detection delay and handling of node mobility.
