Distance Vector Based Sequential Spectrum Sensing Scheme for Cognitive Radio Networks

Article Preview

Abstract:

In this paper, we investigated the problem of spectrum sensing to identify primary users in cognitive radio networks. And then we proposed a sequential spectrum sensing scheme based on distance vector. A reliable factor was introduced into the sequential spectrum sensing scheme. This factor was related to distance and could determine the reliability of individual local decision. Simulation results show that the proposed spectrum sensing scheme can provide better performance, and the probability of sensing error can be reduced to 3% compared to the SPRT scheme.
