الملخص الإنجليزي
In Cognitive Radio (CR) systems, the spectrum handoff which is affecting to the performance of system by main factors such as: link maintenance probability, the number of spectrum handoff, switching delay.
Spectrum handoff may be happen more than once for a wide range of the spectrum available in CR.
This switching change the characteristics of propagation transmission loss which is affects the overall system performance.
Thus, in this paper, the path loss and coverage area are essential factors studied to enhance the system performance and make it more immune to propagation losses.
In this article, we aim to overcome these issues by proposing a systematic selection method to select and assign new appropriate frequency channels efficiently to achieve a better transmission.performance.
Additionally, the adaptation power technique is applied in order to control base station transmitted power and estimate the appropriate coverage area to reduce and avoid interference an + d also to conserve power dissipation in the system.
The combining of these approaches, selection method and power adaptation, is found to be helpful to achieve an efficient spectrum utilization, reduce power consumption, maintain the connectivity link, decrease the number of spectrum handoffs from failure which are very important to improve overall system performance.
The simulation results show a comparison of the proposed strategy with other techniques by increasing the wide of frequency switching up to 64 % and also studies the effect of the adaptation technique on the system performance.
