Network protocols are often analyzed using simulations. We demonstrate how to extend such simulations to check propositions expressing safety properties of network event traces in an extended form of linear temporal logic. Our technique uses the NS simulator together with a component of the MaC system to provide a uniform framework. We demonstrate its effectiveness by analyzing simulations of the Ad Hoc On-Demand Distance Vector (AODV) routing protocol for packet radio networks. Our analysis finds violations of significant properties and we discuss the faults that cause them. Novel aspects of our approach include modest integration costs with other simulation objectives such as performance evaluation, greatly increased flexibility in specifying properties to be checked and techniques for analyzing complex traces of alarms raised by the monitoring software.
