Integrated service has provision for end-to-end QoS to applications over the network. However, it has the problem of scalability. On the other hand, differentiated service enforces the handling of traffic aggregation to provide IP QoS with scalability. In this paper, we present an end-to-end admission control scheme with integrated multi-class traffic in a DiffServ network. This scheme can achieve...
In this paper, we present an analytical framework to estimate the forward link capacity in multi-service cellular CDMA systems. In our analytical framework, a mobile performs the practical base station (BS) selection criterion that the mobile always connects to the largest received power BS. The Gaussian approximation and the lognormal approximation are used in evaluating the resulting signal-to-interference...
In this paper, the multicode (mc) and the variable spreading gain (VSG) access schemes for asynchronous multicarrier code division multiple access (MC-CDMA) systems supporting multirate services are considered. The system capacities for these two multirate access schemes are investigated. A transmit power control is proposed to maintain the link quality and improve the system capacity. Simulation...
This paper examines the performance for the integrated voice and data services in hybrid fiber/coax (HFC) networks through mathematical analysis. Our objective is to obtain the feasible region (FR) for the integrated services subjected to their packet level quality-of-service (QoS) requirements. The analysis is focused on the upstream channel and the performance of the system is evaluated in terms...
