Abstract

Distributed sensor networks are quickly gaining recognition as viable embedded computing platforms. Current techniques for programming sensor networks are cumbersome, inflexible, and low-level. This paper introduces EnviroTrack, an object-based distributed middleware system that raises the level of programming abstraction by providing a convenient and powerful interface to the application developer geared towards tracking the physical environment. EnviroTrack is novel in its seamless integration of objects that live in physical time and space into the computational environment of the application. It contains run-time mechanisms that efficiently abstract groups of sensors by logical objects which maintain aggregate environmental state. Such objects may be logically attached to moving entities in the physical environment, in order to monitor the state of the tracked entity. The performance of an initial implementation of the system is evaluated on an actual sensor network based on MICA motes. Results demonstrate the ability of the middleware to track realistic targets without overloading the sensor network.
