Abstract

Wireless sensor networks are characterized by a large number of non-standardized protocols and varying application requirements. This creates need for a systematic approach to rapidly design and optimize deployment specific protocol stacks. We employ component based optimization as a candidate solution, and use it as a basis for an extensible software framework called CONFab. We treat a particular protocol stack as a collection of interdependent configurable components. CONFab captures a deployment scenario description, relates it to the desired performance metrics, and correspondingly suggests suitable protocol stacks and parameter settings. It utilizes ontology centric knowledge base to select components from a pool of alternatives, reason on their compatibility and, thus create appropriate protocol stacks. The framework is equipped with a number of additional plugins that allow, for instance, to incorporate feedback from deployed systems and user inputs to anticipate network performance. We use a set of well-known MAC and routing protocols to validate the framework on the Indriya testbed in different user specified application and deployment conditions. The results indicate that CONFab with its component based approach helps in obtaining suitable protocol stacks and thereby achieving high performance characteristics.
