PROJECT TITLE :
Performance Comparison of Routing Protocols for Cognitive Radio Networks
Cognitive radio networks (CRNs) have emerged as a promising resolution to the ever-growing demand for added spectrum resources and additional economical spectrum utilization. A giant variety of routing protocols for CRNs are proposed recently, every based on completely different design goals, and evaluated in numerous situations, under completely different assumptions. But, very little is thought about the relative performance of of these protocols, plus the tradeoffs among their totally different style goals. In this paper, we have a tendency to conduct the first detailed, empirical performance comparison of three representative routing protocols for CRNs, below the identical realistic set of assumptions. Our intensive simulation study shows that the performance of routing protocols in CRNs is full of a range of things, in addition to PU activity, some of that are largely ignored by the majority of previous works. We have a tendency to notice that totally different protocols perform well below totally different eventualities, and investigate the causes of the observed performance. Furthermore, we have a tendency to gift a generic software design for the experimental evaluation of CRN routing protocols on a testbed primarily based on the USRP2 platform, and compare the performance of 2 protocols on a half-dozen node testbed. The testbed results ensure the findings of our simulation study.
