architecture - sensors&networking - distributed services - proof of concept   
The technical work will focus mostly on architectural, protocol and software issues. This area is in fact believed to be the true bottleneck in current sensor networks. The challenges to face in developing new technologies for sensor networks are the need for the nodes to be smart, self-configurable, capable of networking together, and the inherent poverty of resources of the nodes themselves. The main thrust of the work will therefore be directed towards the development of new architectural schemes and communications protocols and algorithms at multiple layers, taking into account those specific features. In particular, schemes, which are able to work efficiently in the presence of limited energy, processing power and memory, will be developed.

In the EYES architecture, applications rely on a two-level structure. The lower layer deals with sensors and networking, whereas the upper layer provides distributed services to the application by using the networking and transport capabilities offered by the lower layer. Detailed architectural studies will be carried out during a system architecture workpackage (WP1), whose aim is to produce an open framework for flexible development of new applications.

According to this architectural view, there are two main research workpackages. WP2 (sensors and networking) will develop technology for communications and networking, including internal sensor architecture, distributed wireless access, routing protocols, reliable end-to-end transport, synchronization and localisation of nodes. WP3 (Distributed Services) deals with the service layer, which supports mobile sensor applications, and will address issues and services such as information collection, lookup, discovery, security.

As a vehicle to show the usability of a sensor network, a large-scale sensor network (100+ nodes) will be built and some of the developed algorithms will be implemented and tested (WP4, Proof-of-Concept).
