Abstract
Quality of service (QoS) provisioning is an important constraint in cognitive radio networks. Apart from the heterogeneous service environments, study has to be conducted for the coexistence of multi rate secondary users in the cognitive network. In this paper we focus on the evaluation and analysis of quality of service (QoS) parameters of multi-rate secondary users (SU) in real time (RT) and non-real time (NRT) user applications. The evaluation has been carried out to test the behavior of cognitive ad hoc on demand vector (CAODV) and weighted cumulative expected transmission time (WCETT) routing protocols in multi-rate secondary user test beds using cooperative scenarios. Simulation results are provided to analyze the performance of the above routing protocols.
