Generating Libraries for Rapid Wireless Sensor Network Reconfiguration

This talk discusses early research in the creation of libraries for rapid wireless sensor network (WSN) reconfiguration. Appropriate reconfiguration allows the WSN to save energy while tracking a target. If the target moves slowly enough, the WSN can successfully reconfigure itself during runtime. However, a fast-moving target forces the WSN to use more energy or risk losing track of the target. Our research explores the precomputation of libraries such that a WSN can quickly choose an appropriate configuration instead of calculating one during runtime. Because of the wide variety of situations a WSN can encounter and limits on the size of the library, creating a comprehensive library is not feasible. However, prudent selection of configurations to include in the library will limit the possibility of encountering situations for which an appropriate configuration cannot be selected or adapted.

The proposed application of this concept to mobile sensor scheduling was recently presented as a student abstract and poster at AAAI-08.
