An access control protocol based on estimation of traffic with an adaptive algorithm in multimedia CDMA packet communications

摘要

In a multimedia communication, various types of traffic are handled. Generally, each traffic in a multimedia communication has a different stochastic property. Conventional access control protocols do not consider such characteristics of multimedia traffic. We propose a new access control protocol for multimedia CDMA packet communications in which stochastic properties of multimedia traffic is considers. The proposed protocol controls packet transmissions based on estimation of the instantaneous number of simultaneously transmitted packets. This estimation is carried out by an adaptive algorithm. Simulation results show the advantage of the proposed protocol over the protocol which does not estimate the number of simultaneously transmitted packets.
