Abstract – Ubiquitous computing introduces inimitable requirements for the discovery technique prototype, which lets services and devices become aware of each other without explicit human administration. The vision of ubiquitous computing has been described in terms of the disappearing computer. In this vision, we are free to focus on the interactions of daily life in various domain, rather than attending to the technology assisting us in those interactions, for example in UC discovery service technologies used in location detection and self therapeutic services in healthcare systems. The machine (while perhaps not literally invisible) becomes a tool much like a hammer or pen, easily appropriated and used as second nature. Discovery lets services and devices spontaneously become aware of the availability and capability of peers on the network without explicit administration. In practice, this means that a client can discover and potentially use a device without prior knowledge of it. Although discovery is a necessary component of ubiquitous computing, the wide range of discovery systems in use today reflects the varied needs of the communities from which they originated
