Abstract
To improve system performance related to radio spectrum handover in cognitive radio networks, a novel spectrum handoff mechanism is proposed which is based on the diversity of spectrum's quality and the traffic requirements of secondary users. Simulations are conducted to evaluate its performance in response time, bandwidth utilization and connection keeping probability. It is shown that the designed mechanism is effective in guaranteeing the quality of services of secondary users. © Springer-Verlag Berlin Heidelberg 2012.
