A Hybrid Approach to Increase the Scalability in VANETs

Scalability in VANET environment is an important issue of concern in recent years. Many approaches have been presented in the recent years and compared their merits and demerits with the existing approaches. In the present work a hybrid technique extension to the GPSR protocol is presented which is based on the content based filtering approach and the clustering approach. The filtering approach uses Bloom Filter approach while the clustering uses the mobility based approach. The results are compared with the GPSR approach and the mobility based single hop network approach on the basis of different performance parameters. Results also verifies that the present approach is better as compared to the basic approach.
