Abstract:
Providing access to the Internet or other network services to remote regions with low population density is quite complicated, since telecommunications companies may be unwilling to invest in a communications infrastructure in these locations. A possible solution to this problem is using Vehicular Ad-hoc Networks (VANET) with Delay Tolerant Networks (DTN) architecture in order to provide Internet access and other services to these regions. This is quite a challenging task because it is really difficult to predict when vehicular nodes will be in contact with each other and how long it will remain connected. In this paper , we are proposing a unique VANET/DTN routing strategy based on a new metric called Trend of Delivery (ToD). The results have shown that our proposition had better performance than other classical DTN protocols when applied to VANET. We used the Network Simulator 3 (ns-3) to implement classical DTN protocols as: Epidemic, Prophet and Spray-and-Wait in order to compare with our proposition. The simulation shows a good performance of the proposed strategy, maintaining good delivery rate while keeping overhead low, unlike purely epidemic strategy, where the overhead increases uncontrollably.
