Abstract

The capture effect, discussed in this paper, is generally considered to enhance the system‘s performance in a wireless network. This paper also considers the Randomly Addressed Polling (RAP) protocol in the presence of a fading mobile radio environment. Herein, a deterministic channel, which rules according to inverse &agr; power propagation law, is established to obtain the probability that one collided packet can capture the channel from distance distribution. Through the probability, we analyze the performance of the RAP protocol by using an embedded Markov chain. According to our results, the performance of the RAP protocol does not obviously change in terms of power control, implying that it can be more aptly applied in power control skill than other protocols.
