Efficient TDMA based virtual back off algorithm for adaptive data dissemination in VANETs

With an exponential growth of Internet related technologies, there is an emergence of new class of efficient data dissemination using Vehicular Ad Hoc networks for the safety of peoples. As there are limited number of channels in IEEE 802.11 a/b/g/p standards, so efficient mechanisms are required to allocate the same for new incoming requests from the users. Keeping in view of the same, we propose a modified TDMA based virtual back off algorithm for VANETs. Vehicles are assumed to be arrived using Poisson distribution and served as exponential. By varying the distance from RSUs, we have provided the analysis of end-to end delay for varying speed of vehicles.
