Discovery systems in ubiquitous computing

The introduction of discovery technologies in ubiquitous computing has enabled services and devices become aware of each other without explicit human administration. Discovery is the process by which an entity on a network is spontaneously notified of the availability of desirable services or devices on the network. Many discovery systems were designed with the enterprise in mind and embody design decisions reflecting that intent. The most important dimensions characterizing discovery systems are topology, transport, scope, search and security.
