|Intelligent Sensor Networks||Distributed sensor networks are deployed for urban area monitoring as well as for Intelligence, Surveillance & Reconnaissance (ISR) operations (e.g., underwater sensor networks). The objective of these sensor networks is to observe and interpret gradually (or rapidly) evolving spatio-temporal phenomenon of the environment in which they are deployed. It is necessary to impart intelligence to these sensor networks such that they can make distributed decisions in the event of anomalies, abrupt environmental changes, and detection of targets. Typical control objectives include maximization of coverage area, minimization of energy consumption, improving the target detection probability, and accommodation of failures. It is also important that the local decisions are consistent with the global objectives. In order to make local decisions, the sensor nodes must have the capabilities of distributed learning and real-time pattern discovery.
Furthermore, since the sensor nodes are usually randomly deployed, energy constraints must be considered to maximize the lifetime of the network because battery replacement can be infeasible and time consuming. This requires proper scheduling protocols to optimize the energy consumption. In this regard, the research at LINKS is focused on distributed learning as well as optimization & control aspects of sensor networks..
