Abstract — I-SENSE demonstrates the potential of combining the scientific research areas multi-sensor data fusion and pervasive embedded computing. The main idea is to provide a generic architecture which supports a distributed online data fusion on an embedded system. Due to their high onboard processing and communication power our proposed architecture is designed to perform sophisticated data fusion tasks in realtime. Another goal of I-SENSE is to dynamically change the configuration, thus, to be able able to react to changes in the systems environment. This paper describes ongoing work in developing necessary hard- and software components in order to perform realtime multi-level data fusion. We present the distributed I-SENSE platform and introduce our multi-level fusion framework. First experimental results on embedded image fusion demonstrates the feasibility of our approach.

This article proposes a new framework of the Internet implementation for the purpose to be able to minimize the transmission delay time of time-critical packets. The framework consists of new routers which make possible to work both of two modes (shared mode and exclusive mode) on a same network media, and a protocol to synchronize the timing to change the active mode of routers. Usually, the router acts as a conventional router of the Internet in the shared mode. On the other hand, in the exclusive mode, the router acts as a repeater and transfers packets without any rewriting of packet headers. By changing appropriate routers to the exclusive mode, a certain source and destination pair in the network can be connected as if they are connected directly with an isolated LAN. The timing of the mode changing is managed by a QoS (Quality of Service) management protocol so as to change all of the appropriate routers to the exclusive mode synchronously. As the results, the Internet can provide reserved time-critical communication services by providing synchronous time-division slots of exclusive mode to the connection. 1.
