Stanley III, Public Sector Chief Recursion Software Technology Officer, Internet Business Frisco, TX USA Solutions Group [email protected] Cisco Systems, Inc. San Jose, CA, USA [email protected] Abstract—This paper will discuss the pervasive software Finally, various scenarios that will greatly benefit from and network architecture required to form the foundation of such a platform will be covered that span location-aware, Distributed Knowledge Networks (DKNs) and Intelligent pervasive collaboration, connected home, urban/regional Sensor Networks (ISNs) that span home and office, mobile wide platforms, emergency/first responder, and especially and embedded devices, sensors, autos, and the cloud. highly complex planet-wide intelligent sensor network and earth resources management systems. The paper will highlight how such foundations accelerate the development and adoption of immersive geo-spatial decision Keywords--pervasive software, pervasive fabric, spaces where mashed up isolated data sets from public, pervasive architecture, pervasive applications, private, and/or non-profit sources are combined with human pervasive middleware, mobile, wireless computing networking and social networking capabilities. The Emerging systems, ad-hoc networks combined effects resulting from these combinations will produce higher situational awareness, context aware option I. INTRODUCTION analysis, and interweaved collaborative environments harnessing the swarming nature of humans, machines, and Pervasive software has been discussed in sensors of distributed participatory networks. academia for some time now, but has yet to be realized.

How will it ubiquitous collaborative communications platform that allows change our lives? How does it help facilitate for ad-hoc, dynamic peer-to-peer, peer-to-community, peer- collaboration?

All of which facilitates the provisioning a multi- be realized? What will "pervasive software" look like layer and open-standards based communication, architecturally? What will its capabilities be? What messaging, and trusted fabric that spans a wide range of pervasive applications will result? When will it, and the devices from servers to clients to mobile devices to sensors. applications it enables, get here? In what ways does it The requirements of such a pervasive software platform will help realize the requirements of the business be presented as well as the architecture needed to support architecture? such. It also discusses how this architecture will allow applications and application state to move peer-to-peer It is the aim of this paper to address at various and peer-to-community so that users, and groups there of, levels all of the above aspects of Pervasive Computing. can seamlessly move from one device to another (home<- The good news is that it is the strong feeling of these >mobile<->auto<->work<->cloud) without interruption or loss authors that the foundation for pervasive services is of data. We further go on to describe the "follow me" state here…and we will begin to see the applications that will capabilities, where the content and state follow people, be built on it change all of our lives as they are products, processes, and nodes within the trusted groups launched within the next year. It is an extremely and communities. Capabilities are ideally suited for exciting time where all the necessary ingredients are confederated collectives and communities that participate coming together. There continues to be an explosion more in an ecological way vs. traditional enterprise of inexpensive yet powerful devices for the home, approaches. office, and other mobile/embedded environments (mobile routers for example) that everyone now own and utilize daily. This is aligning with advances in 1 wired/wireless networking, and advances in pervasive a pervasive software platform and underlying meshed software platforms. Advances in IP-based sensor network that is at the heart of the content of this paper. networking and more open-standard geo-spatial techniques, offers newer ways to realize the potential. Bill Gates and Steve Ballmer have each echoed similar sentiments. Gates expressed in this final II.

And Ballmer noted at CTIA WIRELESS & IT in October 2007, "We need to bring together four At VMWorld in San Francisco back in September powerful computing phenomena that exist today: The 2007, Cisco CEO John Chambers said the future of IT desktop PC, enterprise computing, mobile services and business was about a "wave of collaboration running in the cloud and phone devices… The other across barriers and content. There will be a wave of thing which I think our industry needs, so that all of our productivity that will change how we work and the very innovations can add up where the whole is bigger than nature of work itself." "It's about convergence of voice, the sum of the parts, is really a rich platform that video and data all stored in places you have difficulty supports work style and lifestyle innovation on the getting to, such as in the home on small devices." "All phone." [7] this will be enabled by unified communications," he said. The authors of this paper are in complete agreement here. Pervasive services and applications In his speech, Chambers coined it as "Find me, will span all the devices we use today, and indeed follow me, get access to anything you want," and later many that we don’t even realize we are "using", namely closed by stating that: "You will see a second phase of mobile routers, embedded devices and sensors in our innovation via virtualization and collaboration - data, home, office, auto, and in stores, malls, on road, and voice, video, across any combination of data type, any ultimately on and even in our bodies. Will many of device, and any network." [1] these devices be running some flavor of Windows as Ballmer suggests? Certainly. But a tremendous Back in September 2005, Chambers gave a amount of them will not be. presentation to MIT entitled "The Power of the Network to Change the Way We Work, Live, Play, and Learn." III.

The March 2010, Chambers re-enforced these concepts applications and decision spaces taking advantage of "It's not the data center or the user device.
