Operating System Fundamentals for the EYES Distributed Sensor Network

One of the problems related to sensor networks built up from large number of nodes having limited capabilities is the operating system running inside each node. It must provide a lot of functionality and allow easy development of applications, but has very restricted resources (like memory, processing capabilities, and energy). Some of the features are also related to the general nature of the network and applications we are building: it is a distributed system, and made up from several types of mobile sensors. In this paper, we have identified the main requirements of such an operating system and propose an architecture that satisfies them. The results of this study are the first steps in our project and provides the basics for all future work. Keywords—sensor network, distributed operating system, mobile sensor nodes
