Dynamic spectrum access (DSA) based on interruptible spectrum leasing allows secondary users (SUs) to lease a licensed, but idle, spectrum that is owned by primary users (PUs) on condition that the PUs preempt the access to the leased spectrum. This

In recent years, a network based telemetry system has received a great attention as the upcoming telemetry paradigm. This paper considers a network based telemetry system with one master telemetry and two slave telemetries. The master telemetry merge

This paper considers a dynamic spectrum allocation (DSA) for efficient distribution of the spectrum resource by allocating the spectrum to be responsive to demand variations. In this DSA model, a spectrum broker (SB) is responsible for the allocation

This paper considers a dynamic spectrum allocation (DSA) model that a spectrum broker (SB) coordinates the allocation of the spectrum with the regional license inside the region of responsibility. It has a potential to leverage the spectrum utilizati

Underlay spectrum sharing in cognitive radio (CR) networks allows that the secondary user (SU) coexists with the primary user (PU) via primary spectrum sharing to the extent not to deteriorate the primary communication. It provides the SU with more a

In cognitive radio (CR) networks, there are two parameters associated with spectrum sensing: probability of detection (PoD) and probability of false alarm (PoF). The higher the PoD, the better the primary users (PUs) are protected. On the other hand,

In recent years, cognitive radio (CR) has received a great attention due to the ability to improve the spectrum utilization. It allows the secondary user (SU) in the CR network to opportunistically access the licensed spectrum of the primary user (PU

Passive RFID tags, which have no self-battery and just backscatter the energy from a reader, share a common channel. It causes a tag-to-tag collision problem when at least two or more tags communicate to the reader simultaneously. The dynamic frame s
