Cloud Assisted Adaptive Priority Scheduling using Deadline Based Reservation Strategy for VANET

VANET (Vehicular Ad-hoc Network) are emerging as a prominent field of MANETs. VANET provides many lifesaving and commercial services. Scheduling of messages in VANET plays a very important role in case of emergency messages. According to message types is a mandate need Priority based Routing Protocol (PRP) in VANET. The main aim is focus on a safety messaging application for safe driving in distributed environment, i.e., ad hoc manner. Deadline based routing protocol (DBR) is proposed along with priority. Currently there is a lacuna in retrieval of various services provisioning in terms of message delivery on time due to frequently disconnectivity of topology in VANET. To mitigate this problem, proposed a hybrid VANET Cloud Fog computing using DBR (Deadline Based Reservation Strategy) for supporting reliable service provisioning. The requests are queued in different combinations of priorities to apply the scheduling algorithm. Once the combinations are applied, the request with the highest priority is served first.
