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 کاملStochastic Model Based Opportunistic Spectrum Access in Wireless Networks
We present a stochastic model based opportunistic channel access and transmission scheme for cognitive radioenabled secondary users for single data channel. We refer to this scheme as RIBS (Residual Idle Time Distribution based Scheme). In this scheme, the SU randomly senses the channel and if the channel is sensed idle, then it uses residual idle time distribution to estimate its transmission ...
متن کاملOpportunistic spectrum access in cognitive radio networks: when to turn off the spectrum sensors
In cognitive radio networks, spectrum sensing is a critical to both protecting the primary users and creating spectrum access opportunities of secondary users. Channel sensing itself, including active probing and passive listening, often incurs cost, in terms of time overhead, energy consumption, or intrusion to primary users. It is thus not desirable to sense the channel arbitrarily. In this p...
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...
