|Issue Date:||Dec-1995||Citation:||Chua, K.C.,Tan, W.M.,Lye, K.M. (1995-12). Performance of PRMA in a mobile radio channel. Computer Communications 18 (12) : 982-987. ScholarBank@NUS Repository.||Abstract:||The performance of the packet reservation multiple access (PRMA) protocol in a real mobile radio channel that suffers from propagation impairments including multipath fading, shadowing and distant-dependent path loss, is studied by simulation. Significant performance degradations, measured by the number of simultaneous conversations supportable in a cell subject to a packet dropping probability of 1%, are observed. Additionally, receiver capture is also found to be ineffective in increasing this supportable number of simultaneous conversations. A modified PRMA protocol is then introduced, and shown to be capable of improving performance through minimizing premature loss of reservations and avoiding additional collisions that arise due to the channel errors. © 1995.||Source Title:||Computer Communications||URI:||http://scholarbank.nus.edu.sg/handle/10635/62609||ISSN:||01403664|
