ESP Framework: A Middle-ware Architecture for Heterogenous Sensor Networks [Other]

NESL Technical Report #: 2006-12-5


Abstract: Sensor networks are quickly becoming a flexible, inexpensive, and reliable platform to provide solutions for a wide variety of applications in real-world settings. For instance, sensor systems have been used for medical monitoring, detection and classification for defense purposes, and to perform environmental monitoring. The increase in the proliferation of sensor networks has paralleled the use of more heterogeneous systems in deployments. This thesis presents a framework that enables interoperability between varied sensor systems and also details some of the fundamental capabilities needed in such an environment. The ESP framework aims to provide a standard method to manage, query, and interact with sensor network systems. We provide a method to describe sensor systems using ESPml, a XML schema, as the modeling language. The fundamental goal of the schema is to be able to describe sensors in a simple, compact manner while still having the ability to represent essential details such as the general setup, the type of data that can be provided, and the commands that are available. In addition, we present a web services based frameix work that provides the basic capabilities for locating, managing, and querying the sensor systems. Finally, challenges such as authentication schemes, logging services, context integrity, and client interfaces are also explored.
