Query: An Energy Efficient Spectrum Sensing in Cognitive Radio Wireless Sensor
  Networks   The cognitive radio wireless sensor networks have become an integral part of
communicating spectrum information to the fusion center, in a cooperative
spectrum sensing environment. A group of battery operated sensors or nodes,
sensing information about spectrum availability in the radio links, needs an
energy efficient strategy to pass on the binary information. A proper routing
method through intelligent decision making can be a good solution. In this
paper, an energy efficient routing protocol has been introduced and a
performance comparison is made with the existing system in terms of its energy
consumption. The proposed routing technique considers both uniform and
non-uniform clustering strategies and proves to be an energy efficient method
of communication.
