Abstract

Geocasting, a variant of conventional multicasting, uses the location technology to deliver messages. However, recent geocast protocols extensively use flooding and broadcasting approaches. When network load is heavy, the chance of collision will be increased and then packets will probably be damaged or lost. The purpose of this paper is to propose an Adaptive Handshaking-Based Geocasting protocol (AHBG). In this protocol, we employ handshaking-based forwarding for data transmission instead of flooding. Simulation results show that AHBG achieves high delivery ratio (nearly 100%) with low overhead (at least 21% reduction compared with other protocols).
