This study designs and presents routing protocols multi‐channel, multi‐hop cognitive radio sensor network (CRSN), which are based on spectrum sensing, spectrum‐availability …
Research studies in software maintenance are notoriously hard to reproduce due to lack of datasets, tools, implementation details (eg, parameter values, environmental settings) and …
Cognitive radio networks (CRNs) have emerged as a paradigm addressing the problem of limited spectrum availability and the spectrum underutilization in wireless networks by …
In a mobile ad hoc network, the data packet may fail to be delivered for various reasons mostly for route failure, congestion, and battery energy drain. Hence, providing reliable and …
