Abstract
Purpose – This paper suggested a model for sensing security at the cloud computing environment
using the cognitive radio (CR) system. The proposed sensing security technique at the cloud situation
enables the authors to estimate the distance of the IT equipment by means of the perceived
information, namely the value of interfering temperature from the spectrum sensing. The paper aims
to discuss these issues.
Design/methodology/approach – In this paper, how IT devices can communicate within the
current frequency is studied. Based on this, techniques for CR cloud network system of the sensing
security are proposed.
Findings – Based on the information of this value of distance, the user of the electric wave cognition
could maintain security up to the maximum level within the range beyond intervention influence,
deciding the maximum transmission of electricity which is available.
Originality/value – The proposed technique in this paper may lead the user perceiving the electric
wave to select the adapted modulation level by considering the transmitted electricity and the
interference temperature level of the given channel situation.

1. Introduction
Cloud computing is an internet-based type of computing in which various types of
information technology related services and resources are stored and shared. Programs
are stored in a utility data server on the internet, and users can use their computers or
cell phones to upload, save, access, and share data as necessary.
Cloud service refers to a technology or environment that allows consumers and
businesses to use web-based applications to access resources that exist in different
physical locations. Virtualization technology is used to provide a large database. As
shown in Figure 1, the composition of a computing network is characterized as a cloud
