In this paper, we analyze the outage probability of a three-node decode-and-forward (DF) relay network, where the relay adopts a power-splitting protocol to harvest energy from the received signal, and utilizes the harvested energy to forward information. First of all, the theoretical expression of outage probability is derived, and then the closed forms of the optimal amount of harvested energy and...
We consider a spectrum sharing protocol in which a secondary system can operate on the same spectrum with a primary user. In the protocol, the secondary system helps the primary system achieve its target rate by acting as a relay for the primary system. As a reward, the remaining subcarriers can be used for the secondary transmission. In order to alleviate the disadvantages of amplify-and-forward...
The popularity of networks in manufacturing is continuously growing, and the quality of service (QoS) has become one of the most intriguing aspects for both the theory and practice of manufacturing networks. The concept of QoS for manufacturing networks is discussed, together with the classification and modeling of the QoS issues. Then, this paper presents a QoS-aware service framework integrating...
