This paper considers Cognitive Radio Sensor Networks (CRSN). The aim of this paper is twofold: First, we analyze the problem of total energy minimization in CRSN by choosing the best relay for each cognitive sensor node in the network. A node either sends its data packet directly to the Base Station (BS) or forwards to another node; and the latter, in turn,(More)
CRSN (Cognitive Radio Sensor Networks) have recently gained huge interest as an area of research. Naturally, due to energy limitations in WSN (Wireless Sensor Networks), grouping sensor nodes into clusters has been widely adopted by the research community to overcome the issue of limited energy budget and generally achieve high energy efficiency as well as(More)
