Welcome to the home page of SENS, a customizable simulator for wireless sensor network applications.
Abstract: Recent advances in micro electro-mechanical systems and VLSI lithography have catalyzed the miniaturization of sensors and controllers, enabling ad hoc deployment of large-scale wireless sensor networks (WSNs). The considerable cost of deploying and constantly changing large-scale WSNs for experimental purposes makes simulation useful in developing dependable and portable WSN applications. SENS is a customizable sensor network simulator for WSN applications, consisting of interchangeable and extensible components for applications, network communication, and the physical environment. Multiple different component implementations offer varying degrees of realism. Users can assemble application-specific environments with different signal propagation characteristics. SENS allows users to execute the same source code on simulated sensor nodes as deployed on actual sensor nodes, enabling application portability. Furthermore, it provides diagnostic facilities such as power utilization analysis for development of dependable applications. We validate and demonstrate usability of these capabilities through analyzing two simple WSN services.
