In this paper, we propose a Petri Net based model able to characterize the QoS of a Secondary User network in a cognitive radio environment operating in the GSM900 band. The proposed model is quite flexible as that it can consider several Primary User network loads, several Secondary User types of services (that involve semantic transparency or time transparency) and it's able to take into account mistakes of sensing spectrum algorithm used by Secondary Users. Specifically, we derive the response time distribution of Secondary User from which it is possible to obtain an estimation of both the maximum throughput and jitter. The proposed cognitive radio scenario considers a Secondary User synchronized access to the channel with the GSM frame structure.

Abstract

In this paper, we propose a Petri Net based model able to characterize the QoS of a Secondary User network in a cognitive radio environment operating in the GSM900 band. The proposed model is quite flexible as that it can consider several Primary User network loads, several Secondary User types of services (that involve semantic transparency or time transparency) and it's able to take into account mistakes of sensing spectrum algorithm used by Secondary Users. Specifically, we derive the response time distribution of Secondary User from which it is possible to obtain an estimation of both the maximum throughput and jitter. The proposed cognitive radio scenario considers a Secondary User synchronized access to the channel with the GSM frame structure.
