HIPERLAN type I: performance analysis of the channel access control protocol

The high performance radio LAN (HIPERLAN) type 1 specification was adopted as a standard by the European Telecommunications Institute (ETSI) in late 1996. While many contributions on the performance of wireless LANs had been submitted in the standardization effort, certain HIPERLAN performance issues were left unresolved. Most of the published performance work so far has been based on simulations, not the analytic results. In this paper we present an analysis of HIPERLAN channel access control protocol in an ad hoc networking scenario. We derive expressions for the probability of success, the average overhead per-channel access cycle, and the network capacity. Using an M/G/1 queueing model we approximate the average delay using equilibrium point analysis techniques. In addition, a lower and an upper bound on the average delay as a function of the throughput are obtained.
