Overhead-controlled contention-based routing for VANETs

Hooman Sadeghian, Ali Farahani, Maghsoud Abbaspour


Routing of VANETs is a challenging issue that has attracted many attentions of researchers recently. Contention based routing protocols have good congruity with high mobility of nodes in this kind of networks. Prevention from forwarding duplicate packets is an important challenge in such routing protocols. Indeed, such duplications can reduce scalability and efficiency of contention based routing protocols. On the other hand, the prevention method can affect advantages of such routing protocols. In this paper, we proposed 2 new routing protocols by adding 2 new methods to an existing contention based routing protocol to decrease overhead of duplications. Simulation results show that overhead decreases significantly while preserving end-to-end delay and delivery ratio in suitable values.
