Integrated Adaptive Protocol of Random Multiple Access

Calculation of Service Delays in Multiple-Access Systems with Conflict Resolution

“…(1) more than k new requests arrive and a conflict takes place or (2) no new request arrives up to the moment when • the system completes the reception of the last request participating in the conflict;…”

“…If, during a time a of propagation of the signal to abonents, any package does not arrive, then the channel is considered to be free again. Otherwise, with the arrival of the ( ) k + 1 th package, the retranslator transmits a conflict resolution package (CRP) that contains the number L of orders of priority of conflict resolution along with some housekeeping data to the broadcasting channel and then the signal of the beginning of the conflict resolution phase and the duration of L , as is proposed in [2].…”

“…The values of the average delay of a request and the average number of requests we are interesting in a system are related by the well-known Little relationship [2] N W = l and N T Q Q = l , where l (the average rate of arriving requests) is the limit of the ratio of the expectation of the number of the requests arrived in a interval [ , ] 0 t to the time t as t ® ¥, provided that the mentioned limit exists.…”

“…In this article, quality indices of service in telecommunication systems using a multiple access protocol with a conflict resolution procedure are investigated [1,2]. The chief distinctive feature of the protocol being considered is a combination of the ideas of using a busy signal, conflict-dependent parallel processing, and a conflict resolution procedure for organization of efficient multiple access.…”
