Abstract:

The authors analyzed the movement characteristics of vehicular communication network; proposed a clusterbased network topology discovery strategy with resident agent in vehicular communications network (VCBRP); and provided the corresponding clustering algorithm. The proposed VCBRP protocol was compared with CBRP and DSR protocols through computer simulations. Simulation results show that VCBRP algorithm has better performance in terms of load balancing, with lower end to end transmission delay and less route request times in highspeed environment, and the packet delivery rate has improved to some extent.
