The WiMedia specifications for high data rate ultra-wideband communication is an emerging protocol with its first products available on the market. One use case is wireless networking based on the Internet Protocol. Conference rooms or offices can be equipped with access points to provide high speed Internet access. Our intention is to establish WiMedia wireless networks in public transportation vehicles,...
Providing guaranteed quality-of-service (QoS) for resource-hungry multimedia applications over wireless fading channels is challenging. Traditional layered architecture fails miserably in providing the QoS requirement of high throughput, low latency demand of these kinds of applications in wireless mobile networks. Cross-layer design approaches are critical for efficient utilization of the scarce...
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...
Bluetooth application developers have to address technical challenges imposed by the heterogeneity of the wide range of hardware and software capabilities present in the Bluetooth enabled devices. The wireless nature and the mobility of devices place an added strain on resource management. To manage such diversity of software and hardware, middleware based solution with the emphasis on transport level...
In modern communication networks different traffic classes require different quality of service (QoS) guarantees. It is therefore important for the benefit of both communication network users and network providers to meet each traffic class requirement while minimizing the utilized network resources. In this paper the failure-aware idle protection capacity reuse concept, FAIR for short, is presented...
This paper specifies an advance reservation and co-allocation protocol for grid computing, and a simple framework for supporting well defined charging models. The protocol supports arbitrary level of nesting, that is a reservation may be to a virtual resource (a set of resources). The work is motivated by the need for advance reservation in the RealityGrid project. However the protocol is a generic...
The design of micro-mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time multimedia applications. We present a new load balancing hierarchical model for micro-mobility management for the wireless access network. The scheme includes a novel anchor selection algorithm....
