Title: Hierarchy of Reconfiguration in Sensor Network Software Systems

Abstract: In-situ reconfiguration is indispensable in sensor network deployments. It is required for efficient management and upgrade of software in large scale sensor networks, re-tasking a deployed network or for recovering a deployed system from crippling bugs or malicious intent. A spectrum of techniques for re-programming have been proposed. The major approaches are: <BR> 1. Full binary upgrade supported by TinyOS/Deluge mechansim that allows arbitrary changes to the functionality but incurs a high transmission and storage cost. <BR> 2. The SOS operating system for sensor nodes that consists of a static kernel that is extensible through modular extensions and can be installed and updated over the air. <BR> 3. Application specific virtual machines (ASVMs),which are domain specific interpreters built on top of TinyOS and enable limited high-level changes to the functionality by injecting concise application level scripts. <BR> <BR> The three approaches vary in the cost and the flexibility of the updates that they can support. The nature of the update determines the most suitable technique. We have built a system that supports this complete hierarchy of reconfiguration.
