Monitoring of physical phenomena is one of the most promising application fields of wireless sensor networks. In this paper, the authors focus on obtaining the shape of a forest fire. In this kind of applications, the information sensed by network nodes is usually transmitted to a base station located at the border of the network, where it is finally processed. However, such an approach requires that a large amount of data is transmitted through the network. In this paper, they assume that network nodes are able to collaborate in order to obtain an approximation of the forest fire shape without any base station, in a completely distributed way. They propose and analyze two techniques for performing this approximation.
