Abstract

Most of the work on geocasting has been done for mobile ad-hoc networks and vehicular ad-hoc networks. This paper presents a novel Geocast technique with the hole detection in the geocast region for underwater environment. The proposed model named as Routing and Multicast Tree based Geocasting (RMTG) has been designed for underwater sensor networks. Here we propose a theoretical model for underwater geocasting RMTG that uses greedy forwarding and previous hop handshaking to route the packets towards the geocast region. This technique further disseminates the data within the geocast region by creating a multicast shortest path tree. The technique also proposes a method of hole detection inside the geocast region and a virtual area based routing around the boundaries of the geocast region to reach the geocast region from opposite side. This model provides an efficient geocast technique in terms of node mobility handling, lesser memory utilization, lesser calculations and a better end to end latency. In addition to this the proposed model does not use flooding inside the geocast region that is used in most of the geocasting techniques and also for guaranteed data delivery inside the geocast region, the proposed model does not use the planarization graph concepts.
