Abstract
Based on the new characteristics of mobility and interactivity of cognitive radio ad-hoc networks nodes, a cooperative spectrum sensing model was firstly proposed, in which, the weight coefficient was assigned to each SU node according to the spatial differences between SU nodes and the test results were weighted on average;Secondly, the possible interference of the authorized signal under the system model was analyzed, and the mathematical model of energy efficiency optimization with multi-constraints was established;Then, a NLMS based algorithm of interference probability was put forward to solve the energy efficiency optimization problem under multi-constraint conditions;Finally, the efficiency of the sensing model and allocation algorithm was verified through experiments.关键词
