A Hybrid Approach for Location-based Service Discovery in Vehicular Ad Hoc Networks

Abstract

This paper deals with the design and implementation of a location-based protocol for service discovery in mobile ad hoc environments. Our approach is based on geocast addressing of control messages. Moreover, it combines a reactive method -- propagating discovery requests -- with a proactive method -- disseminating service advertisements -- into a hybrid approach. For the evaluation of the protocol an experimental environment was set up. This paper presents the design of the protocol and results of experimental evaluations.
