Using Joint Adaptation of Transmission Power and Contention Window Size in Improving VANET Performance

In this paper, the authors present a novel format for vibrant adaptation of transmission power and Contention Window (CW) size for information propagation in Vehicular Ad-hoc NETworks (VANETs). The anticipated format uses a shared approach to adapt transmission power at the PHYsical (PHY) layer and Quality-of-Service (QoS) parameters at the Medium Access Control (MAC) layer and incorporates the Enhanced Distributed Channel Access (EDCA) mechanism of 802.11e to implement a priority based Vehicle-To-Vehicle (V2V) communication. In this paper, an algorithm for joint adaptation of transmission power and contention window to improve the performance of vehicular network in a cross layer approach is used.
