Analytical study of broadcasting in 802.11 ad hoc networks

IEEE 802.11 technology becomes attractive with the implementation of various broadcast applications. For these applications, one of the main performance indices is the mean notification time namely the interval between consecutive successful receipts of the same source’s packets. In this paper, we develop an analytical method to study the ad hoc 802.11 network performance with broadcasting stations. The method based on a Markov model allows the estimation of the mean notification time and the optimization of the packet generation time. The developed method has been validated by simulations and has demonstrated a high accuracy of notification time estimation as well as the its efficiency in broadcasting optimization.
