Data Rate Control and its Effects on Working of Cognitive Radio Adhoc Networks

摘要

In cognitive radio adhoc networks the utilization of spectrum without spectrum sensing is a difficult task because of the fluctuations of the availability of spectrum holes. Hence the location awareness is must for concurrent transmission area where both primary users and secondary users can exists. In this paper we examine the data rate control effects on the working of cognitive radio adhoc networks. The planned algorithm sufficiently increases the secondary user data transfer rate as much as possible without restraint the attainable primary data rate. As per result found the data rate control algorithm increases the concurrent transmission area with increasing data rate of secondary user without disturbing the primary user. The result shows that It is possible to increase the data rate and concurrent transmission region of the cognitive radio adhoc networks and hence increase in the spectrum utilization efficiency.
