Abstract |
In wireless networking domain, diverse wireless technologies are utilized for sharing data and providing data services. The protocols used in VANETs are DYMO and AODV+. Both of them can provide internet by communicating with Road Side Units (RSUs) which are static. This application has performed well, still leaving some challenges for the designers to be met in advancements. In this work, a novel architecture 3G/UMTS networks are integrated with VANET networks in which a minimum number of gateways, per time instance are selected to connect ordinary vehicles with the UMTS network. In the proposed architecture, AODV is used in forming a VANET and a radio link to connect a VANET to 3G/UMTS base station through a gateway. There is an instance, where a node must be given priority. The gateway must give highest priority in serving priority needed node by broadcasting about the arrival of vehicle and requesting the remaining nodes in a VANET to clear the road for a while. Simulation is carried out for priority node and priority-less node and better results are obtained. |
