Research Area:  Vehicular Ad Hoc Networks

Abstract:

The limitations of the transmission control protocol/Internet protocol (TCP/IP) model have given birth to a new futuristic trend called named data networking (NDN), focusing on retrieving the desired data by using content names instead of host addresses. In this context, we proposed another NDN architecture named hybrid communication in vehicular ad hoc networks (VANETs) via named data network (HCIV-NDN) to reduce packet loss, eliminate the unnecessary message exchange, and to assume that in one cluster not all receivers nodes rebroadcast. Also, it investigates the NDN concept to vehicle to road side unit (V2R), vehicle-to-vehicle (V2V), and road side unit to infrastructure (R2I) plus vehicle-to-infrastructure (V2I) communications to enlarge the connectivity of vehicles. The vehicles are clustered and can communicate with the base station, with road side unit (RSU), and among them to define a new data dissemination protocol. Hence, the HCIV-NDN mechanism applies two types of timers to select some farthest nodes as forwarder to rebroadcast packets at different times. Thus, we study the performance of our HCIV-NDN with node density effects for smart cities and then we compare it with the existing location-based deferred broadcast (LBDB) scheme. Simulation results exhibited that HCIV-NDN scheme achieves more than 90% in terms of the cache-hit ratio when the percent of consumers interested in the same data is about 50%. Then it performs better than LBDB in terms of satisfaction ratio, packet loss ratio, and the average delay in a suburban scenario.
