Abstract

Recent advances in micro electro-mechanical systemsand VLSI lithography have enabled the miniaturizationof sensors and controllers. Such minitiarization facilitatesthe deployment of large-scale wireless sensor networks(WSNs). However, the considerable cost of deployingand maintaining large-scale WSNs for experimental purposesmakes simulation useful in developing dependableand portable WSN applications. SENS is a customizablesensor network simulator for WSN applications, consistingof interchangeable and extensible components for applications,network communication, and the physical environment.Multiple component implementations in SENSoffer varying degrees of realism. Users can assembleapplication-specific environments; such environments aremodeled in SENS by their different signal propagation characteristics.The same source code that is executed on simulatedsensor nodes in SENS may also be deployed on actualsensor nodes; this enables application portability. Furthermore,SENS provides diagnostic facilities such as powerutilization analysis for development of dependable applications.We validate and demonstrate usability of these capabilitiesthrough analyzing two simple WSN services.
