Spatial Computing: An Emerging Paradigm for Autonomic Computing and Communication [chapter]

Franco Zambonelli, Marco Mamei
2005 Lecture Notes in Computer Science  
In any case, the capability of self-organization and selfadaptation cannot abstract from the capability of the system of becoming "contextaware", i.e., of letting components to perceive the local properties  ...  The first two characteristics (large size and network dynamism) compulsory call for selforganizing and self-adapting approaches, enabling those systems to exhibit -both at the network and at the application  ...  In spatial computing, this simply translates in the capability of perceiving the local properties of space, which in the end reflect some specific characteristics of either the network or of some application-level  ...
