Enabling extensibility of sensing systems through automatic composition over physical location

Networked sensing systems are increasingly adopted in many applications, but today's systems are generally single purpose and hard to extend. This paper addresses the problem of enabling developers to develop extensible networked sensing systems. We propose a design methodology, which centers on a novel automatic composition service where the sensor processing software modules are parameterized by a physical location region. The automatic composer automatically configures the processing and communication occurring in a networked sensing system based on up-to-date sensing needs and sensor device availability. Our approach also enables adaptability and robustness against sensor failures.
