Reciprocally opportunistic spectrum access
The problem of opportunistic spectrum access in cognitive radio networks (CRNs) is considered in this paper. Especially, we discuss designing distributed learning protocols for non-cooperative secondary users (SUs) to efficiently utilize the spectrum opportunities. It is well known that the SUs’ selfish behaviors will result in a network collapse. Each SU is thus enabled to form conjectures ove...
متن کاملOpportunistic Spectrum Access Learning Proof of Concept
This paper presents the results of first ever implementation of learning algorithm for opportunistic spectrum access (OSA) in lab conditions. The OSA scheme consists of two USRP N210 platforms, one acting as primary users of a primary network and another as secondary user. Primary user network generates carriers with a pre-defined probability of occupancy through an OFDM modulation scheme imple...
متن کاملOpportunistic Spectrum Access Study of CORAL Platform
As the requirement of spectrum is increasing with the advent of new technologies, cognitive radio networks have got tremendous attraction in recent days. Since the concept of cognitive radio is new, there are a few number of cognitive radio platforms have been introduced in the literature. CORAL is WiFi like cognitive radio platform developed by communication research centre (CRC) operated in l...
متن کاملDynamic Spectrum Sharing by Opportunistic Spectrum Access with Spectrum Aggregation
The rapid growth of wireless services and the breakneck proliferation of wireless devices continue to strain limited spectrum resource. While the need for efficient spectrum sharing mechanisms has been emphasised, opportunistic spectrum access has been considered as a promising mechanism for dynamic spectrum sharing. However, although the idle spectrum could exist, it is usually rather fragment...
متن کاملImplementing opportunistic spectrum access in LTE-Advanced
Long term evolution advanced (LTE-A) has emerged as a promising mobile broadband access technology aiming to cope with the increasing traffic demand in wireless networks. However, the enhanced spectral efficiency offered by LTE-A may become futile without a better management of scarce and overcrowded electromagnetic spectrum. In this sense, cognitive radio (CR) has been proposed as a potential ...
