Fractal Analysis of Intraflow Unidirectional Delay Over W-LAN and W-WAN Environments

This paper has analysed unidirectional delay traces of a diverse set of IPv6 microflows routed over W-LAN and W-WAN environments. Using a number of time-domain and frequency-domain estimators the paper examines the existence and intensity of long-range dependence in packet delay when viewed as time-series data. The correlation structures of...

A Dynamic QoS Provisioning Model for Network Mobility

This paper proposes a dynamic QoS provisioning model for network mobility. The basic idea of network mobility NEMO is to keep connectivity whilst the network changes its point of attachment. To achieve this, sufficient resources need to be provisioned for the entire mobile network. In the model, the packets are...

Accurate Vehicular Positioning Using a DAB-GSM Hybrid System

The Global Position System GPS and the Global Navigation Satellite System GLONASS are based on a satellite system. Much work has been carried out on a non-satellite positioning system using the existing Global System of Mobile Communications GSM infrastructure. This leads to a GPS-GSM positioning system that manufacturers claim to...

Distributed Systems Support for Adaptive Mobile Applications

Mobile applications must operate in environments which experience rapid and significant fluctuations in the Quality of Service QoS offered by their underlying communications infrastructure. These fluctuations may be the result of explicit changes between networks, increased competition for network resources or degradation of service due to environmental factors. In order...

Limbo: A Tuple Space Based Platform for Adaptive Mobile Applications

Mobile computing environments are characterised by significant and rapid changes in their supporting infrastructure and, in particular, in the Quality-of-Service QoS available from their underlying communications channels. Applications which can operate in these environments and take advantage of changing QoS require distributed systems support platforms. The current state-of-the-art in such...

Using space robots to fix ailing satellites?

According to Canadian engineers at Queen's University, there are now more than 8,000 satellites in orbit around the Earth. Of course, if they stop to work correctly, these satellites will not be able to be repaired from the ground and will become space junk. So these researchers have developed a...

When it comes to China, is Skype the new Yahoo?

Any major Western company doing business in China is collaborating with the government to some degree. We know this. Chinese citizens know this. The best case scenario is probably Microsoft or Google's operations where access to certain information is limited. The worst case, until now, has been Yahoo's explicit cooperation...

Semantic guardians for our computers?

If your computer has never crashed, it's because it has been built on another planet. The microprocessors we use are faster and more complex year after year, increasing the risks of being hit by 'functional bugs.' This is why University of Michigan (U-M) researchers have started to develop a system...
