Mobile service providers (MoSPs) emerge, propelled by ubiquitous availability of mobile devices and wireless communication infrastructures. MoSPs’ customers satisfaction and consequently their revenues, largely depend on the quality of service (QoS) offered by wireless network providers (WNPs) at a particular location and time of a mobile service usage. This chapter presents a novel business me...

In this paper we proposed dynamic adaptive guaranteed quality-of-service (QoS) provisioning scheme over General Packet Radio Service (GPRS) wireless mobile links. The guaranteed QoS media access control (GQMAC) protocol and the accompanying adaptive prioritized-handoff call admission control (AP-CAC) protocol are used to maintain QoS guarantees. The effect of mobile handoffs are also taken into...

The current Internet service model treats all requests equivalently, both while being processed by servers and while being transmitted over the network. Growing usage and diversity of applications on the Internet makes Quality of Service (QoS) an increasingly critical issue, especially in the e-commerce realm. This paper covers the motivation and considerations for adding QoS to the Internet, t...

Today’s networks struggle providing a data transmission service of sufficient quality. The demands imposed on the networks by current applications, such as multimedia applications, cannot easily be met. Error-free data delivery within tight time constraints are required by some applications in order to provide user satisfaction. However, most networks do not naturally provide means for the spec...

A Mobile Ad Hoc Network (MANET) is a collection of mobile nodes, which dynamically form a temporary network, without using any infrastructure like wireless access points or base-stations. There are many real life applications based on Quality of Service (QoS) support provided by MANETs. But QoS provisioning in MANETs is a very challenging problem when compared to wired IP networks keeping in vi...

With the growing adoption of the Service Oriented Architecture (SOA) in the industry and the wide deployment of Web services, users are increasingly requiring services that are capable of meeting their quality-of-service (QoS) requirements. In this paper, we propose a novel framework for QoS-aware Web service provisioning, which relies on QoS brokers, to mediate between clients and service prov...

This paper presents a system, where a model of the user’s tasks is used for automatic service composition in smart spaces. In the system service modeling is decoupled from resource modeling. We present a model for quality of service (QoS) based service composition, integrating it with our resource management scheme. A component acting on behalf of the user composes the service with the aim of m...

Zusammenfassung In Serviceorientierten Architekturen können Geschäftsprozesse durch Komposition von lose gekoppelten Services realisiert werden. Sind entsprechende Services auf Service-Marktplätzen vorhanden, kann ein Service-Konsument zwischen Services wählen, die die von ihm benötigte Funktionalität bereitstellen, basierend auf deren Dienstgüte (engl.: Quality of Service – QoS). Diese QoS-bas...

As more and more Web services are deployed, Web service’s discovery mechanisms become essential. Similar services from different sources often exhibit quite different Quality of Service (QoS) levels. For service selection and management purpose, it is necessary to explicitly, precisely, and flexibly specify various constraints and QoS metrics for Web services descriptions. This chapter provides...
