We develop cognitive radio networking methods for a heavy-traffic model in which the channel is always occupied by primary users. This contrasts with the interference-avoidance approach for the non-heavy-traffic model, in which primary users have idle times, and secondary users are allowed to use the channel at those idle times. We use an “underlay” approach to cognitive […]
Technical objects constrain what users do with them. They are not neutral entities but embody information, choices, values, assumptions, or even mistakes embedded by designers. What happens when a technology is designed in one culture and used in another? What happens, for example, when a Chinese user is confronted by Roman-alphabet-embedded interfaces? In this book, Basile […]
Cloud-based radio access networks (C-RAN) have been proposed as a cost-efficient way of deploying small cells. Unlike conventional RANs, a C-RAN decouples the baseband processing unit (BBU) from the remote radio head (RRH), allowing for centralized operation of BBUs and scalable deployment of light-weight RRHs as small cells. In this work, we argue that the […]
In this paper, we introduce NDNFlow: an open-source software implementation of a Named Data Networking based forwarding scheme in OpenFlow-controlled Software-Defined Networks (SDNs). By setting up an application-specific communication channel and controller layer parallel to the application agnostic OpenFlow protocol, we obtain a mechanism to deploy specific optimizations into a network without requiring a full […]
This paper provides a novel approach for automatically enhancing voice quality with reference to user’s Quality of Experience (QoE). It is based on in-service quality assessment in Voice over the InternetProtocol (VoIP). The proposed scheme includes three phases: (1) automatic user quality assessment with diagnostic features, (2) fault localization in case of user quality experience degradation, and (3) dispatch control […]
