Cognitive Radio Network (CRN) nodes called the Cognitive Radio (CR) nodes, sense the presence of a Primary User (PU) activity. The sensing reports from all the CR nodes are sent to a Fusion Centre (FC) which aggregates these reports and takes decision about the presence of the PU, based on some decision rules. Such a collaborative sensing mechanism forms(More)
—Traceroute program is extensively used in wired networks to track the route packets take on their way to a destination. However, traceroute is often less effective in wireless networks where broken routes are too common. In this paper, the design of wtracert is presented that employs optimal timeouts to provide a faster implementation of the traditional(More)
