In this paper we describe an LTE based demonstrator of the Universal Link Layer API (ULLA) and Cognitive Resource Manager (CRM) modules that are developed in ARAGORN project. The demonstrated LTE system comprises one LTE TDD eNode B and one User Equipment (UE). We first introduce ULLA and CRM framework and then demonstrate their suitability to be implemented with the existing LTE equipments. We show...
In the multi-cell environment, the approaches that are suitable for the single cell scenario may cause excessive interference to other cells and become suboptimal. In this paper, we present a number of receiver-centric power allocation schemes that take into account the detrimental impact of allocated resources to the neighboring cells, and use it as a guideline in determining the appropriate power...
Alert monitoring of psychological health for web text is to evaluate and forecast the unhealthy psychological status of web users by the technology of web text mining. Based on the idea of “Service Distributed and Management Centralized”, this paper proposes a cloud architecture for psychological health analysis and describes the service component representation, workflow customization and workflow...
This International Standard addresses the creation, analysis and sustainment of architectures of systems through the use of architecture descriptions. A conceptual model of architecture description is established. The required contents of an architecture description are specified. Architecture viewpoints, architecture frameworks and architecture description languages are introduced for codifying conventions...
To cope with rapidly increasing Internet usage nowadays, providing Internet services using multiple servers has become a necessity. To ensure sufficient service quality and server utilization at the same time, effective methods are needed to spread load among servers properly. Existing load balancing methods often assume servers are homogeneous and consider only one type of resource, such as CPU....
Active networks provide a programmable user-network interface that supports dynamic modification of the networkpsilas behavior. Network nodes, in addition to forwarding packets, perform customized computation on the messages flowing through them. Individual packets carry executable code, or references to executable code. Resources in an active network mainly comprise of CPU and bandwidth. The inherent...
Modern networks provide QoS model to go beyond best-effort services, but current QoS models are oriented towards low level network parameters (e.g. bandwidth, latency, jitter) application developers on the other hand are interested in quality models that are meaningful to the end-user and therefore struggle to bridge the gap between networks and application QoS models. Network-aware applications are...
