Modeling and Optimization of Data Gathering Protocols in Wireless Sensor Networks

CSI INTERNAL SEMINARSPEAKER: Professor Bhaskar Krishnamachari, CENGABSTRACT: The most dominant approach to the development of querying and data-gathering protocols in wireless sensor networks can be characterized as "design by intuition, validate by simulation". Given the severe resource constraints in these systems, it is essential to complement this perspective with mathematical modeling and optimization. Such modeling has both descriptive and prescriptive uses, which we illustrate through a couple of case studies. In the first study, we derive scaling laws for query-based sensor networks, identifying the application conditions under which it is possible to deploy arbitrarily large sensor networks when the resources per node are kept bounded. In the second, we use an optimization framework to design a fair and efficient rate-control scheme for data gathering.
