Die Wissensgesellschaft stellt jedem in den verschiedenen Lebensbereichen komplexe Anforderungen. Die OECD hat im Rahmen des DeSeCo-Projektes einen konzeptuellen Referenzrahmen für die Bestimmung und Messung von Schlüsselkompetenzen entwickelt, mit denen Individuen in der heutigen Gesellschaft bestehen und diese mitgestalten können. Der Themenbereich Internetworking bietet für Lehr-Lernprozesse...

This paper describes the design of a wearable multiparametric physiological signal moniror, a continuously running internetworking system for monitoring multiples physiological parameters of individuals during daily tasks. A pi.otot_vpe, measuring parameters such as electrocardiogram, oximetiy and non-invasive blood pressure is now in test. The system peiforms real-time processing on the signal...

Architecture. There’s a lot of it about. Do we need it? Recent years have seen considerable publishing activity in the area of “internet architecture”. This paper steps back and asks a more radical question: is an internet architecture a good thing at all? Are we at a point in the development of distributed communications systems where the concept should be replaced by a different way of dividi...

The traditional cloud-based Internet of Things (IoT) architecture places extremely high demands on computers and storage cloud servers. At the same time, strong dependence centralized servers causes major trust problems. Blockchain provides immutability, transparency, data encryption based safety to solve these problems IoT. In this paper, we present a distributed secure edge computing using mu...

Bandwidth-intensive and delay-sensitive applications demand ATM technology to be brought into every desktop. However, it is very costly in terms of both hardware and software to replace a traditional LAN such as Ethernet and token ring by an ATM network. Therefore, internetworking LANs with an ATM backbone network is considered a cost-effective and most promising solution for bringing ATM into ...

In this paper, we propose an architecture for environmental information services that make it possible for applications to adapt in dynamically changing environments. These services provide information necessary for applications to adapt to its environment. Unlike other information services, the information provided includes not only raw information but also abstract or policy-applied informati...

Intrusion detection has become a basic infrastructure to guarantee the security of most internetworking applications. With more internetworking applications in the Internet nowadays, enormous volume of audit trails are produced for the analysis within intrusion detection. For this reason, it is critical to reduce the detection computation of intrusion detection to meet the realtime detection re...

Mobile end-systems frequently change their point of attachment to the network. In such an environment, in order for mobile devices to run without disruption, an inter-networking infrastructure is needed. In addition, a common networking protocol is required which can support network-wide mobility. Mobile devices also need to communicate with the existing pool of information servers and le serve...

The Licklider Transport Protocol (LTP) is the “convergence layer” of choice in Interplanetary networks based on Delay-/Disruption-Tolerant architecture. It was designed for long-delay scheduled-intermittent links, offering either a reliable or an unreliable service, with “red” and “green” parts, respectively. aim this article to present multicolor LTP, LTP version consisting series enhancements...

We show how multimedia applications with real-time requirements can be supported in a distributed system. A UNIX system has been modiied to give soft real-time support. The modiications include deadline-based scheduling, preemption points and prioritized interrupt processing. In addition, a system call interface for real-time application programming has been designed. We justify the modiication...
