Analysis of Efficient Medium Access Control Protocol for Vehicular Ad-Hoc Network

Computer Engineering

VANET represents some extraordinary difficulties including dropping out of associations as the moving vehicle moves out of the scope range, joining of new hubs moving at high speeds, dynamic change in topology and availability, time changeability of sign quality, throughput and time delay. For asset administration in VANET, a medium access control convention is utilized, which ensures that restricted assets are circulated effectively. In this work, an efficient Multichannel Cognitive MAC (MCM) is developed, which assesses the quality of channel prior to transmission. MCM employs dynamic channel allocation and negotiation algorithms to achieve a significant improvement in channel utilization, system reliability, and delay constraints while simultaneously addressing Quality of Service. TDMA reduces transmission collisions due to node mobility on the control channel by assigning disjoint sets of time slots to vehicles moving in opposite directions and to road side units. TDMA likewise lessens transmission impacts along these lines making Control Channel (CCH) more reliable and provides high throughput over Service Channel (SCH) via maximum channel utilization.
