Abstract
In recent years, standardization bodies, academia and automobile manufacturers are working together to develop vehicular ad hoc network (VANET) based communication technologies. VANETs apply various channels like service channels (SCHs) and control channel (CCH) for supplying unbarred street safety facilities and the better condolence as well as effectiveness of driving. In this paper, we suggests a VCI known as variable control CH interval (VCI) MAC (multichannel medium access control) scheme which reduces safety message transmission time and helps to minimize collision probability when the vehicle node increases in the road by using k-means and donkey-smuggler optimization algorithm. The donkey-smuggler algorithm used to find the shortest path among the nodes and k-means clustering algorithm is used to group the sensor nodes. The distance ratio connecting with SCHs and CCHs can be effectively modified in MAC scheme. To improve the intermissions based on traffic situation, a model is carried out called Markov model and this process is called as stochastic process. Conceptual analysis and the simulation resulted to the recommended scheme which is capable to assist IEEE 1609.4 and IEEE 802.11p protocol. While retaining the methodized channelling of condemnatory safety data on control CH, the MAC scheme consequentially improves the higher saturated throughput and gives effective channel utilization of service CHs and minimizes transmission interval of service packets.
