We consider the discrete memoryless symmetric primitive relay channel, where, a source $X$ wants to send information to a destination $Y$ with the help of a relay $Z$ and the relay can communicate to the destination via an error-free digital link of rate $R_{0}$ , while $Y$ and $Z$ are conditionally independent and identically distributed given $X$ . We develop two new upper bounds on...
Consider a symmetric primitive relay channel, where, the source X wants to send information to the destination Y with the help of a relay Z, the relay Z can communicate to the destination Y via an error-free digital link of rate R0, and Y, Z are conditionally independent and identically distributed given X. This paper presents two new upper bounds on the capacity of such relay channels, where the...
Software Defined Network (SDN) is undergoing an increasingly high popularity among various schemes of networking deployment. The main advantage of SDN lies in its flexibility in controlling network traffic, which arises from decoupling the control plane and the data plane of network devices. However, despite of the valuable merits of SDN, the outage of data forwarding should not be ignored. The drawback...
To satisfy the stringent requirement of capacity enhancement in wireless networks, cooperative relaying is envisioned as one of the most effective solutions. In this paper, we focus on the problem of capacity enhancement by way of relay stations (RSs) placement, which is a critical task of network planning and deployment to achieve an efficient and scalable network design. To fully exploit the performance...
