Abstract
This work introduces a new analytical method for performance evaluation of wireless packet-oriented networks. Unlike traditional call admission control procedures commonly used for performance evaluation of wireless networks, this paper deals with the problem of coupling connection and packet level QoS characteristics by analysis. At connection level we use the Blocked-Calls-Cleared (BCC) model, whereas at packet level we use the Blocked-Call-Interfered (BCI) model which has no immediate feedback from packet level to connection level about lost data. At connection level we use the convolution algorithm which defines the feasible state space at packet level. At packet level we take into consideration wireless interference (soft blocking). The traffic is modeled as multi-rate Binomial-Poisson-Pascal (BPP-) traffic at connection level and on-off traffic at packet level. We obtain individual performance measures for each service, both at connection level and at packet level. By case studies we investigate the trade-off between the two levels to meet Grade of Service (GoS) requirements for cellular networks with WCDMA radio interface.
