Abstract

This paper presents a geocast technique for underwater sensor networks. The model named as Routing and Multicast Tree based Geocasting (RMTG) (TRACE'10, Bhopal, India, 2010; ICWET'10, Mumbai, India, 2010) has been designed for underwater sensor networks. In our previous work (TRACE'10, Bhopal, India, 2010; ICWET'10, Mumbai, India, 2010) we proposed only a theoretical model for underwater geocasting. The RMTG technique uses greedy forwarding and previous hop handshaking to route the packets towards the geocast region and further disseminates the data within the geocast region by creating a multicast shortest path tree. We also presented various link broken scenarios along with their solutions. The proposed model does not use the flooding technique to deliver the packets inside the geocast region that is used in most of the geocasting techniques. In this paper, we present the simulated RMTG model. The simulation results show that the proposed model provides an efficient distribution of data in the geocast region in terms of node mobility handling, packet delivery ratio and a better end-to-end latency. Most of the work on geocasting has been done for mobile and vehicular ad hoc networks; hence we present in this paper a novel simulated model for underwater environment.
