Intelligent Roaming for Nomadic Computing

This paper provides details of a new system architecture enabling users / applications to roam seamlessly while they are actively processing executable code and / or communicating with remote entities. This architecture effectively decouples the running of applications from the underlying environment, facilitating both security and opportunistic processing on transitory resources. This decoupling also promotes the ability to create multiple clones of an application for performance gains. To improve the performance of the system, fuzzy logic [E. Cox, 1955][L. Biacino and G. Gerla, 2002][C. Vasudevau et al., 1994][S. Dick, 2005] and case based reasoning (CBR) [Aamodt et al., 1994][D. Leake, 1996] have been applied to the system to better regulate activities such as job migration between resources or client connection handover from one proxy to another. The paper provides a full description of the system and some simulation results to illustrate its functioning.
