In this paper, we study the optical attenuation behavior of several kinds of single-wall carbon nanotubes (SWNT) including pure SWNT, modified with COOH, NH2, and OH all with the thickness of 5 m. We focus on attenuation in communication wavelength range between 1260 and 1640 nm for non-amplification, and 1520-1570 nm for optical amplification setup.

We investigate the ergodic uplink resource allocation problem for secure communication in relay-assisted orthogonal frequency-division multiple access (OFDMA)-based cognitive radio networks (CRNs) in the presence of a set of passive eavesdroppers where relay nodes assist the legitimate users to transmit their messages.

In this paper, we develop and analyze three limited-feedback resource allocation algorithms suitable for uplink transmission in heterogeneous wireless networks (HetNets)

In this paper, we address a power-efficient resource allocation problem in virtualized wireless networks (VWNs) using non-orthogonal multiple access (NOMA). In this set-up, the resources of one base station (BS) are shared among different service providers (slices), where the minimum reserved rate is considered for each slice for guaranteeing their isolation.
