Personalized Web Service Provisioning to Mobile Users USING Policy-based Profile and QoS Management

Abstract

In the last few years, a rising proportion of the workforce is becoming more and more mobile, meaning that organizations must consider this new trend in their corporate and IT strategies. The expectation of employees now is that they can retain access to their corporate services as they move to new locations, using various kinds of handheld devices. This chapter describes our proposed broker-based system for Web services provisioning to mobile users with quality of service (QoS) requirements. It describes a set of brokers collaborating to provide tailored services to mobile users while they move from one site to another in their corporate and partners’ networks. Access to QoS-enabled Web services complies with the policies of the user‘s home site. Policies are a key component of the system as they are involved at different levels: authorization, QoS specification, QoS service monitoring, and service selection.
