    256 Octave algorithms are used to compute rssi and position datas in order to generate more accurate positions datas and a regularized map. Different types of algorithm may be available.

     257Octave algorithms are used to compute rssi and position datas in order to generate more accurate positions datas and a regularized map.
     258These algorithms may be seen as plugins, then different types of algorithm may be available.

    261262The Gateway task is to read on demand the information saved in DB tables and send these results by using the appropriate format to the end-user through the Sensei framework.

    265 The LetiBee plugin is based on a skeleton plugin and its HandleRequest method. Most of datas are reachable using GET methods, each making a request to the database to get the up-to-date datas. Published datas are listed below.

    270 The communication from the gateway to the end-user will be done using a text file. The Letibee WSAN is thinked like a geographic information database. This database contains nodes identities, positions (§Erreur : source de la référence non trouvée), measures and their histories (§Erreur : source de la référence non trouvée), estimate of others positions values using any kind of algorithms (§Erreur : source de la référence non trouvée). All these information will be send through the Sensei framework using the appropriate protocol and xml format.

     274This database contains nodes identities, positions, measures and their histories, estimates of others positions values computed via algorithms written in Octave.
     275All these information will be send through the Sensei framework using the common protocol and xml format.
