The purpose of this work is to automate the analysis of ad hoc routing protocols in the presence of attackers. To this end, a formal model of protocol behavior is developed in which time is modeled by a set of constraints on the time of occurrence of events, enabling the representation of partially ordered timed events and asynchronous communication. Data variables are represented symbolically, capturing a range of distinct executions in each expression. Given a formal description of Ad Hoc On Demand Distance Vector Routing Algorithm (AODV) and a desired safety property (route stability), an analysis by a naive semi-decision procedure discovers an instance of an attack that leads to a violation of the property.

Abstract. The systematic design, validation, and verification of systems for biomedical experiments in laboratory and clinical applications are complex due to the highly stochastic nature of biological systems. This paper presents a platform framework for the modeling of these biological components in the context of system-level analysis that enables formal validation and verification of biomedical devices. Looking forward, the capabilities of this platform enable the development of more efficient and effective experimental biomedical systems.
