- Abstract
Future intelligent transport systems would heavily rely on Vehicular Ad hoc Network which provides seamless services to the driver on national high-ways. This paper proposes priority based RSA algorithm (p-RSA). The proposed algorithm replaces road side unit with dynamic cloud to reduce the physical infrastructure from the network, provide larger scope of services maintain quality of service to the users. pRSA being on dynamic cloud gives information of the entire traffic to all the vehicles in the range and also the central controlling unit. During call for an emergency service, nearest Police Control Room van is sent a SOS (distress signal can be interpreted as Save our Soul) and at the same time nearest Police Picket and Medical services are alerted. Being on global positioning system and cloud even during misty or foggy conditions every vehicle would know where exactly it is heading and even if a target comes close to other vehicle a warning would flash on the screen with loud beep, the speed would be automatically cut-down to maintain the distance between the vehicles, not only ahead of it, but also behind the target vehicle. Scheduling of pRSA has been compared with first come first serve (FCFS), smallest data size first (SDF) and new method using Deadline and Size of Data (NDS) algorithms on the basis of skew, the priority factor increased by 93.75, 31.25 and 18.75% in comparison to FCFS, SDF and NDS algorithm respectively. Bandwidth consumption and energy utilization are 12.0 and 5.56% less than NDS.
