A ZHLS Based Geocasting for Broadcasting Messages in VANET

Wang-Cheol Song and Muhammad Shoaib
Abstract—Geocasting is used for dissemination of messages in defined geographical locations. It is very useful in traffic information system where warning messages are openly needed to be disseminated in different areas. One major problem in VANET geocasting is that if there exist islands that are not directly connected within the geocast region, the delivery become impossible. In order to overcome this issue in this paper a new Zone based Geocasting algorithm is presented in this paper. The area is divided into different zones including roads. Routing path is defined in form of zones, instead of GPS region or nodes in order to make sure that message is delivered to all zones in the geocast region. Furthermore if there are islands in the geocast regions, they are identified by zone database. Different routing paths are set for multiple islands to make sure they got the geocast message. Our experiments prove using zone based algorithm better performance in term of delivery guarantee can be achieved.

Index Terms—VANET, geocasting, ZHLS, delivery guarantee, island.
