Embedded device cooperative system using Java bytecode instrumentation

Recently, various embedded devices have become equipped with network functions for communication among themselves. In a network middleware with embedded devices (e.g. Jini) to cooperate with each other on networks, a device can use functions provided by other devices. However, because the function is defined by its interface, all programming interfaces of certain functions must be built into a client device beforehand so that the client device can use the functions. Therefore, already existing client devices cannot exploit newly released functions. In this paper, we propose an embedded device cooperative system to solve the problems by adapting dynamic program generation using Java bytecode instrumentation technology. We implemented the proposed system and evaluated its performance from processing time and memory usage perspectives.
