This stems from the fundamental need and nature of mobility: - Users are moving: users can frequently change their location; while moving, they prefer to retain access to their resources, including local and remote computers and applications. Computers are moving: lap-top computers frequently change their location and need to transparently maintain their function despite changed location. - Data is being moved, frequently in the form of objects: with the advance of component based computing and the needs of collaborative environments, it will increasingly be the case that objects with data as well as the code for manipulating this data are transferred across the network. Applets are an introductory pervasive form of mobile objects. - Mobile agents are increasingly deployed: benefits, such as improving the locality of reference, improving failure semantics, representing disconnected users, make them suitable for use in low-bandwidth communication environments, electronic commerce, etc. - Wireless networks are a natural environment for mobility: the lack of wires make them ideally suited for mobile entities. The following mobility and collaboration topics are relevant for the workshop: ------------------------------------------------------------------------------ - New network architectures and high speed networks increase the difference between local and remote access, making them similar to memory hierarchies (first & second level cache, primary memory, secondary memory) and making the case for local reference stronger. Moving the activity towards the source of data and vice versa naturally results from deploying mobility. - Mobility is analogous to real world solutions (traveling salesman, buyers). In electronic commerce, using mobile agents to represent the buyers and sellers assumes the mobility of both. - Mobility is inherent to survivability. In the same way that migrating birds or nomadic tribes move where the resources are, so mobility moves entities towards the resources. If areas lack certain aspects (communication, computing power, or sources of information), mobile entities can move towards areas where such resources exist). - Mobility causes security concerns. There is no clear answer at the moment, only a lot of research; this alone could be the topic for a whole workshop. Particular topics of interest include agent- and host-specific forms of authentication and delegation, determining and enforcing authorization policies for agent and host information and resources, deploying security for mobile agents, objects, and code, and building mobile infrastructures that are trustworthy. - Improving collaboration among human actors and among software agents is an active area of research. Collaboration technology provides models and tools to support novel, more effective, and more efficient mechanisms for achieving shared tasks and goals. Typical collaboration research does not address the mobility of the collaborators, yet mobility of humans and of code is an increasing part of the context within which collaboration takes place. - Collaboration is often orthogonal to mobility. Collaboration can increase the productivity by parallelizing mobile entities, it might be required to achieve security, locating of mobile agents or some resources, etc. Collaboration is hard to achieve in presence of mobility, but in such a case, its benefits are even more apparent than if deployed for stationary solutions. Authors are expected to identify the key infrastructure components that enterprise architects must include in their designs so as to enable a specific collaborative aspect within the enterprise. For example, what are the critical infrastructure component that enable collaboration of mobile workers? - Finally, both mobility and collaboration are intrinsic characteristics. If it weren't for mobility we would still be trees (George Cybenko, at Dartmouth workshop on Transportable Agents). If it weren't for collaboration, the trees would be dumb and sole players. The workshop will encourage the papers that can articulate the levels of mobility that are achievable within an enterprise, as well as different infrastructure requirements related to these levels.
