3:30 pm - 5:30 pm Panel - Mobiquitous computing and spontaneous networking: are we there yet? Where will we go?
This panel is intended to serve as a discussion/critique of the "state-of-the-art" in mobile/ubiquitous computing from all perspectives physical medium, networking, devices, systems, data management and applications. During the panel, special emphasis will be given to systems and solutions devised to hide the complexity arising from the ever-broadening range of ICT devices, network-based services, technologies and protocols, and the related bewildering array of configuration procedures that surround and pervade the end user life.
Despite a decade of research into the area, we are seeing on one side very limited deployment of mobiquitous computing technology, and on the other side we are not witnessing a true simplification in the usage of such technologies. The panel will address issues related to the deployment of mobile/ubiquitous computing solutions and technologies, such as

how close are we to seeing their widespread use?
is complexity a limiting factor in their deployment?
what role is played by automatic, adaptive and self-regulated solutions, in short, spontaneous networking technologies and solutions?
who will invest in the needed infrastructure?
what social and technological barriers remain?
whether the problem is a lack of usable applications?
are there no good applications because the underlying technology is still very limited?
is there a lack of reference standardization and interoperability efforts?

5:00 pm - 6:30 pm Panel - Security and Services in Mobiquitous Computing
Service oriented computing has significantly grown over the last few years, especially in the context of the web. Yet, applications for mobile computing almost never use the service model. Is there a reason behind this, except inertia? Or should mobile devices and applications use service computing ideas to become a part of the web of computing and be truly "ubiquitous." Even if they want to, will the existing "wired" security mechanisms suffice? A combination of the underlying physical layer insecurity and the resource restrictions on devices have combined to make wireless systems, especially ad hoc networks, significantly less secure---or is that so? Can wireless networks be made as secure as wired networks? If so, what is needed? Or is this a losing battle, and wireless networks will never be as secure as their wired counterparts?
