Abstract

Spectrum handoff in cognitive radio networks is to have a seamless switch between channels consequently, a high quality of service for the secondary users. This paper proposes three techniques for spectrum handoff. The first proposed one based on the low priority user leaves the channel to another channel. The second proposed model based on the low priority user stays on the same channel with resuming its transmission when the high priority user finished its transmission. Finally, the third proposed model based on the low priority user stays on the same channel with restarting its transmission when the high priority user finished its transmission. The obtained results indicate that the three proposed system models give different queuing delay performances for each user. The techniques of the models and the obtained results are important for evaluating the total system time, service time and queuing delay for secondary users. Consequently, the quality of service for the secondary users and hence the useful for cognitive radio network design and optimization will be obtained.
