¿µ¹®³»¿ë¿ä¾à The next generation PC will consists of small and wearable or implantable devices. So the middleware for next generation PC requires following features and functions :
o Extremely lightweight and low power consuming
o Supporting dynamic network plug and play and mobility management
o Distributed communications and securities between wearable devices
o Supporting profile management for various applications and device
o Dynamic re-configuration of middleware functions

And the wearable middleware, i.e., the middleware of wearable computers, has to provide following functions to satisfy above features.

o Component-based modular structure: The wearable middleware consists of a set of specific middleware software which is implemented in the form of a software component. And each middleware component can be installed or uninstalled selectively on demand basis. This enables expansion and reduction of middleware capability.

o Dynamic reconfiguration: It reconfigurates the middleware functions according to the needs from applications dynamically. When a system executes a new application, the system checks the middleware functions - S/W components - existing in itself and then downloads required components from network server if necessary. Unused components may be removed from the system to get more memory space.

o Openness-oriented architecture: Wearable middleware provides APIs of each component. Therefore developers can implement their own software of wearable middleware independently as long as their code meets the interface. Application programmers can develop a program regardless of communication protocols and transmission medium.

o API: Wearable middleware consists of the basic APIs and extended APIs. This specification only defines the basic APIs, but additional APIs can be added easily for future extension.
