Ubiquitous e-service is one of the most recent links in the chain of evolution that
has characterized the different eras of the internetworking environment. In this
dissertation, the notion of ambient e-services is defined to identify a new scope of
mobile e-services in an ubiquitous environment, addressing dynamic collective efforts
between mobile users, dynamic interactions with ambient environments, the moment of
value, and low cost provision. We present an ambient e-services framework
characterizing three supporting stacks followed by several ambient e-service
applications. We propose an ambient e-service environment that explores the promise of
exploitation of the collective wisdom of proximal mobile users.
In order to leap the trust barrier for the user to embracing these ubiquitous
e-services, we propose an Autonomous Trust Model for exploring collective wisdom in
the ubiquitous environment (hereafter termed “U-ATM”) as an instance of ASEM.
ASEM (Ambient e-Service Embracing Model) addresses the core elements (of
relevance to the integrated concern of trust, reputation and privacy) required for
assuring such desired features as convenience, safety, fairness and collaboration for
mobile users when they engage with ambient e-services. The U-ATM highlights the
distributed peer-to-peer interactions under an ad-hoc network composition. It especially
accommodates the dynamic short-lived identity characteristics and lightweight
computational capacity of mobile devices. The U-ATM we have developed is based on
the ZigBee architecture as a collaborative application in the upper layer of the
ubiquitous environment. U-ATM design concepts are elaborated and evaluated. A
simulation is conducted. Simulation outcomes for trust decision quality enhancement
show significant improvement over traditional designs. U-ATM makes it possible for
users to collaborate with the nearby user groups for establishing a reliable and
trustworthy interaction environment. It also facilitates and empowers the potential
benefits of various ubiquitous e-service applications.
