摘要：Spectrum efficiency and energy efficiency are two critical issues for wireless communicationnetworks. In the past years, much effort has been made to enhance capacity of wireless communication networks viavarious technologies such as cognitive radio. Meanwhile, cognitive radio has emerged as a promising paradigm toimprove the spectrum usage efficiency and cope with spectrum scarcity problem through dynamically detecting andre-allocating white spaces in licensed radio band to unlicensed users. In order to achieve this requirement, alternatepath selection routing in cognitive radio networks is proposed that saves the energy by efficiently selecting theenergy efficient path in the routing process. It investigates how a CR user senses multiple channels and determinesthe optimal transmission duration and power allocation. When performing optimization, take energy efficiency,throughput, and interference with the primary users into consideration and find a closed-form solution fortransmission duration for chosen channels. It is shown that the proposed optimization approach significantlyimproves energy efficiency and throughput of CR networks. The proposed work is simulated through the NS2Simulator.
