Opportunistic spectrum access (OSA) has been regarded as the most promising approach to
solve the paradox between spectrum scarcity and waste. Intelligent decision making is key …

Spectrum frequency is a valuable resource for wireless communication but very limited in its
availability. Due to the extensive use and ever increasing demand of spectrum bands by …

Small cells constitute a promising solution for managing the mobile data growth that has
overwhelmed network operators. Local caching of popular content items at the small cell …

Providing economic incentives to all parties involved is essential for the success of dynamic
spectrum access. Cooperative spectrum sharing is one effective way to achieve this, where …

Big data has been emerging as a new approach in utilizing large datasets to optimize
complex system operations. Big data is fueled with Internet-of-Things (IoT) services that …

In this paper, the non-orthogonal multiple access (NOMA) technology is integrated into
cognitive orthogonal frequency-division multiplexing (OFDM) systems, called cognitive …

This paper presents a comprehensive analytical study of two competitive secondary
operators' investment (ie, spectrum leasing) and pricing strategies, taking into account …

Mobile crowdsensing (MCS) is a new paradigm of sensing by taking advantage of the rich
embedded sensors of mobile user devices. However, the traditional server-client MCS …

In this paper, we tackle the spectrum allocation problem in cognitive radio (CR) networks
with time-frequency flexibility consideration using combinatorial auction. Different from all …

Network slicing is one of the key enabling technologies for 5G due to its ability to customize
and “slice” a common resource to support diverse services and verticals. This paper …
