A Censored and Ordered Sequential Collaborative Spectrum Sensing Scheme based on Evidence Theory for CRAHN
نویسندگان
چکیده
This paper proposes a censored and ordered sequential collaborative spectrum sensing scheme for cognitive radio ad hoc network (CRAHN). The scheme uses the ordered of the sensing data reliability for enabling the Dempster Shafer theory of evidence sequential combination. A preceding censored process removes the nodes having insignificant sensing data to the broadcasting sensing result process. The advantage of ordered sequential and censored mechanism will help to reduces communication resources (the energy consumption, the coordination and overhead in control channel and the sensing result collecting time) while keeping the same sensing performance compared with the conventional centralized cooperative spectrum sensing.

Secure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...
متن کاملAdaptive Scheduling of Collaborative Sensing in Cognitive Radio Networks
In this paper, we aim to discover more spectrum opportunities in limited sensing delay. We construct a MAC-layer sensing framework for fast discovery of spectrum opportunities. Specifically, we employ the sequential probability ratio test and develop a collaborative sensing scheme for multiuser to collaborate during multi-slot. Moreover, we propose a novel adaptive scheduling of collaborative s...

In the absolutely continuous case, order statistics, record values and several other models of ordered random variables can be viewed as special cases of generalized order statistics, which enables a unified treatment of their theory. This paper deals with discontinuous generalized order statistics, continuing on the recent work of Tran (2006). Specifically, we show that in general neither re...

In this article introduce the sequential order statistics. Therefore based on multiply Type-II censored sample of sequential order statistics, Bayesian estimators are derived for the parameters of one- and two- parameter exponential distributions under the assumption that the prior distribution is given by an inverse gamma distribution and the Bayes estimator with respect to squared error loss ...
