On the Performance of VDTN Routing Protocols with V2X Communications for Data Delivery in Smart Cities
Résumé
VDTN concept and V2X communications capabilities can be utilised for an efficient data collection and delivery in smart cities. Here we present performance comparison of four lightweight VDTN routing protocols: First Contact, Epidemic, Spray and Wait, and MaxProp in terms of its percentage of message delivered, latency, overhead ratio, and hop counts. Overall results show that Spray and Wait and MaxProp show high performance in most of the scenarios, while each also shows potentials for improvements. We also present simulation results where buses with predetermined routes were introduced to the network and observe that it generally increases the delivery performance. These results are our starting point towards a work-in-progress for a bus and cars assisted data delivery protocol for VDTN in smart cities.
