An evaluation model for integrated services on CDMA wireless LANs

Abstract

This paper proposes a performance evaluation approach for integrated voice and data services on CDMA wireless LANs. For random access schemes, dynamic behavior of a CDMA channel implies that we must be cautious in choosing an evaluation model which has to include the effect of dynamic error rates. The approach shown in this paper is to employ a Poisson error model which takes the occurrence of errors as a Poisson process and the occurring rate is dependent on the channel traffic. Based on this assumption, a continuous-time Markov chain model can be further developed to evaluate the throughput and delay performance. This approach can certainly apply to evaluation of many random access protocols.
