We consider a multi-channel opportunistic communication system where the states of these
channels evolve as independent and statistically identical Markov chains (the Gilbert-Elliot …

We consider the following fundamental problem in the context of channelized dynamic
spectrum access. There are M secondary users and N¿ M orthogonal channels. Each …

Opportunistic spectrum access (OSA) that allows secondary users to independently search
for and exploit instantaneous spectrum availability is considered. The design objective is to …

We design distributed spectrum sensing and access strategies for opportunistic spectrum
access (OSA) under an energy constraint on secondary users. Both the continuous and the …

We consider a cognitive radio network with distributed multiple secondary users, where
each user independently searches for spectrum opportunities in multiple channels without …

We consider how two secondary users should interact to maximize their total throughput in a
two-channel sensing-based opportunistic spectrum access network where spectrum …

In this paper, the cooperative caching problem in fog radio access networks (F-RAN) is
investigated. To maximize the incremental offloaded traffic, we formulate the clustering …

The increasing popularity of wireless communication and multimedia applications yields a
growing demand for radio spectrum. However, most of the commercially interesting …

In hardware-constrained cognitive radio (CR) ad hoc networks, secondary users (SUs) with
limited sensing capabilities strive to discover and share available spectrum resources …

Cooperative sharing of spectrum among one primary user (PU) and multiple secondary
users (SUs) helps to enhance the throughput of the whole system. In this paper, we propose …
