Dependability and Accountability for Context-aware Middleware Systems
Andrew C. Rice, Alastair R. Beresford · 2006
In this paper we present a framework to provide dependability through accountability. Our proposal exploits the asymmetry present in the majority of sensor data processing to cheaply validate events and processing which occurs at various points in a distributed middleware system. We exemplify our framework with reference to two real-world distributed location middlewares. We adapt one of these to evaluate our framework and present performance results
