Reactive Sensor Networks Project

We will construct the system in the following steps:

• Mobile code support - implement mobile code support for languages other than Java. The system will support interpreted and compiled languages on embedded, Windows NT, Unix, and Linux systems including at least one parallel supercomputer.

• Multi-resolution multi-sensor fusion - develop coding techniques that support multi-resolution transmission of information. Low resolution information can be sent with very low latency. The amount of data resolution provided is a function of bandwidth. Multi-resolution information may be "fused" during transmission to reduce bandwidth usage. An explicit trade off will be made between data fusion and redundancy for increased error tolerance.

• Agile adaptation - resource allocation will be done dynamically using resource bounded optimization techniques. Program profiles expressing answer quality as a function of resources used will be established by empirical experimentation. Meta-reasoning keeps the overhead of this process to a minimum.

• Testing - we will find methods of invoking aberrant behavior in the system. The goal of this is to establish limits of stability, efficiency, and robustness. Comparisons will be made with theoretically optimal processing. We will attempt to use these results to develop theoretical bounds to this approach.
