| Summary: | International audience This paper presents SAMi, a context aware Information sharing Middleware, for a dynamic pervasive computing environment such as a Mobile Ad-hoc NETworks (MANET). SAMi can be used by colocated devices to share information according to the context of users and their environment. It applies latent semantic modeling techniques and adopts techniques from service discovery to search files efficiently. A preliminary prototype has been developed to simulate MANETs and to implement the middleware. A number of experiments have been performed to evaluate major features of SAMi. Based on these experiments, we found SAMi a promising middleware to facilitate information exchange among co-located devices
