Distributed Fair Transmit Power Adjustment for Vehicular Ad Hoc Networks

摘要: Improving the safety of drivers and passengers by wirelessly exchanging information between vehicles represents a major driving force for design vehicular ad hoc networks. In heavy loaded 802.11-based network, however, safety-related packets might collide frequently cannot be decoded receiver, thus they not effective in increasing level on roads. this paper, we propose to use transmit power control order reduce packet collisions, while taking into account goal networks, i.e. safety. While previous work has addressed issue primarily optimizing network capacity and/or connectivity, optimization criterion improving built upon concept fairness: higher sender should selected at expense preventing other send/receive their required amount information. fully distributed localized algorithm called D-FPAV (distributed fair adjustment networks) adaptive which is formally proven achieve max-min fairness. Furthermore, investigate effectiveness robustness through extensive simulations based realistic highway scenario different radio propagation models
