The Smart Sensor Web (SSW) project was a two year effort sponsored by the Deputy Undersecretary of Defense for Science and Technology (DUSD(S&T)). The vision of the SSW is an intelligent, web-centric distribution and fusion of sensor information that provides greatly enhanced local situational awareness, on demand, to warfighters at lower echelons (battalion/squadron and below). The project examined critical technical issues associated with developing such a system in a joint operational context, including Army, Marine, Air Force and SOF elements. Key constraints in an SSW system include energy, communications bandwidth, latency, and information presentation. This analysis is focused on information generation as far forward as possible to minimize bandwidth requirements and maximize the use of continually improving processing and memory capability. It also focuses on the problem of information fusion and presentation, ensuring that only mission relevant and understandable information is presented to the warfighter. The key mechanism for addressing these concepts is the SSW test bed, a combination of virtual and live assets. Two operational vignettes were used during the second experiment using the test bed: (1) dismounted infantry conducting operations on urban terrain, and (2) the employment of wide-area search munitions such as the Air Force's Low Cost Autonomous Attack System (LOCAAS) in a cooperative attack environment. This paper will focus on the concept for the experiment, some of the key technical issues addressed, the interplay of the simulation methods used, and results from the final live experiment conducted in January 2002.
