A Cooperative Spectrum Sensing Scheme Based on Trust and Fuzzy Logic for Cognitive Radio Sensor Networks
This paper proposes a cooperative spectrum sensing scheme based on trust and fuzzy logic for Cognitive Radio Sensor Networks (CRSN). The CRSN nodes use the T-S fuzzy logic to make local decisions on the presence or absence of the primary user’s (PU) signal, and then use a censoring method to only allow the relatively reliable decisions sent to the fusion center. Utilizing a trust evaluation sch...
متن کاملFuzzy Logic Based Spectrum Sensing Technique for Cognitive Radio
A cognitive radio is a type of intelligent radio system. It automatically detects available spectrum in a given frequency band. It automatically and intelligently changes its parameters. These parameters include transmission and reception. Therefore, frequent wireless communication is achieved for a given frequency band at specific location. There are multiple techniques used to sense and avail...
متن کاملCooperative Spectrum Sensing Using Hard Decision Fusion Scheme
Abstract—Cooperative spectrum sensing using energy detection is the efficient method of detecting the spectrum holes in a particular band of interest or channel by combining the information gathered by multiple CR users. In this paper, we study the hard decision fusion scheme using Logical ̳AND‘ and the Logical ̳OR‘ rule and a brief introduction of Soft and Quantized fusion scheme. Simulation com...
متن کاملTwo-Stage Spectrum Sensing Scheme Using Fuzzy Logic for Cognitive Radio Networks
Spectrum sensing in cognitive radio networks allows secondary users to sense the unused spectrum without causing interference to primary users. Cognitive radio requires more accurate sensing results from unused portions of the spectrum. Accurate spectrum sensing techniques can reduce the probability of false alarms and misdetection. In this paper, a two-stage spectrum sensing scheme is proposed...
متن کاملCluster Based Spectrum Sensing Technique for Cognitive Radio Networks Using Fuzzy Logic Controller
As many kind of spectrum sensing techniques have been introduced for various wireless technologies. These spectrum sensing models have been improved the spectrum usage and have also opened up new opportunities for the different wireless applications to utilize the radio spectrum more effectively. To exploit these opportunities, the wireless transceivers need to be more intelligent to access the...
