In this paper, we propose an optimal power allocation algorithm for a cognitive radio (CR)
network where a D2D pair as two secondary users (SUs) exchange their information through …

In this paper, we consider a two-way amplify-and-forward relaying scheme, which consists of
multiple transceivers and r relay nodes. Assuming that both the transceivers and the relays …

Considering a two-way amplify-and-forward (AF) relay network and aiming to
simultaneously maximize the two users' mutual information lower bounds in the presence of …

In this paper, we consider energy usage in a three-node, two-way relay system with
stochastic data arrivals and Gaussian channels. Specifically, we allow for a set of …

Vehicular networking is envisioned to be a key technology area for significant growth in the
coming years. Although the expectations for this emerging technology are set very high …

Efficiency and security are major concerns with increasingly higher importance in modern
wireless communications. These two concerns are especially significant for multi-user …

Cooperative communication is a promising technique for wireless communication systems
where wireless nodes cooperate together in transmitting their information. Such …
