The effectiveness of the work performed during disaster relief efforts is highlydependent on the coordination of activities conducted by the first responders deployed in theaffected area. Such coordination, in turn, depends on an appropriate management ofgeo-referenced information. Therefore, enabling first responders to count on positioningcapabilities during these activities is vital to increase the effectiveness of theresponse process. The positioning methods used in this scenario must assume a lack ofinfrastructure-based communication and electrical energy, which usually characterizesaffected areas. Although positioning systems such as the Global Positioning System GPShave been shown to be useful, we cannot assume that all devices deployed in the areaor most of them will have positioning capabilities by themselves. Typically, many firstresponders carry devices that are not capable of performing positioning on their own, butthat require such a service. In order to help increase the positioning capability of firstresponders in disaster-affected areas, this paper presents a context-aware positioning modelthat allows mobile devices to estimate their position based on information gathered fromtheir surroundings. The performance of the proposed model was evaluated using simulations,and the obtained results show that mobile devices without positioning capabilities were ableto use the model to estimate their position. Moreover, the accuracy of the positioning modelhas been shown to be suitable for conducting most first response activities.Nota general
