Abstract: Need of spectrum resources have increased due to rapid growth of wireless multimedia applications, but as this spectrum is inefficiently used it has become scarce. Cognitive Radio network (CNR) solves current spectrum in efficiency problems and offer users a best wireless accessing environment depending on dynamic spectrum allocation.Due to involvement of more number of user’s spectrum allocation and scheduling should be wisely done. If proper spectrum allocation is not done, the probability of collision increases in the network which in turn degrades the network performance. A new technique known as Improved Quality of Service Scheduling (IQS) is proposed in order to avoid collisions and to improve the Quality of Service (QoS). IQS enhances the QoS parameters. In this proposed technique network bipartition is done and each region is provided with a Cognitive radio (CR)base station, it allocates appropriate scheduling to each node which lies in its region. Here, spectrum allocation is based on priority, real-time and non-real-time video transmission applications are considered for priority considerations. This leads to increase in network performance. The simulation results convey that, IQS decreases the overhead ratio, collision probability, delay and also increases throughput and network efficiency.
