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.

Our motivation in this work is the desire to support mobile users with services tailored to their needs and to their home profiles as they move from one site to another in their corporate or partners’ networks. To attain this goal, three main aspects need to be considered. First, we need to identify the mobile worker’s device in use at any particular time and its capabilities. Second, we need to identify the mobile user preferences and functional and non-functional service requirements, such as the minimum level of QoS he/she is willing to accept. Third, a close cooperation between home and visited locations needs to be established to negotiate and agree on issues related to the user profile.
