SWORDFISH: A framework to formally design WSNs capturing events
Simone Campanoni, William Fornaciari · 2007
A Wireless Sensor Network (WSN) consists of spatially distributed autonomous devices equipped with sensors and radio communication capabilities. They can act in a cooperative manner for monitoring environmental parameters like pressure, temperature, acceleration, light, humidity, etc. The typical WSN design problem is to discover a proper set of sensors and their spatial distribution, so to enable the monitoring of relevant parameters for the application, while concurrently optimizing some design goals (e.g., cost, reliability, lifetime and energy requirements). In this paper we present part of the SWORDFISH (Sensor netWORks Development Framework Integrating Simulation and Hardware optimization) project, aiming at providing a design and verification environment for WSNs, including in the design loop the simulation of physical events and a formal verification of the WSN desired properties against the network optimization goals. In particular, it is presented the overall design framework, the approach to model properties and goals of the network and some representative case studies showing the value of a toolsuite gathering WSN formal optimization/planning and environment simulation.
