Scalable Coordination Architectures for Deeply Distributed Systems (SCADDS)
Abstract
The SCADDS project explored and demonstrated scalable coordination mechanisms for deeply distributed and dynamic systems. Nodes in these systems were heterogeneous, having a range of sensing, actuation and communication capabilities. These systems raised many challenges for distributed system and network design. The first was a shift from node-centric, to data-centric network architecture. Both scalability and long lifetime called for extensive processing of data within and among the nodes of the sensor network. Rather than streaming all sensor readings back to a central site for processing, nodes autonomously exchanged data, filtered out uninteresting events, and identified patterns of interest. The second challenge was to build systems that were truly self-configuring; able to adapt efficiently to ad hoc deployment and both environmental and network dynamics. This paradigm shift required new network architecture.
