In this thesis, we propose an advertisement-based middleware called SAMi to allow nomadic users to share information according to their interests, contexts and stay times. In SAMi, information sharing is usually by distributing advertisements and queries. In order not to overload the environment with unnecessary advertisements and queries, we propose an approach to parameterise advertisement policies according to users’ profiles and contexts. The parameterisation process is performed semi-automatically by analysing users’ information sharing activities. SAMi classifies files hierarchically and presents them in a file tree. Files are advertised according to user’ profile and context. During advertisements, the middleware advertises files by using descriptions at the shallow and depth level of the file tree. Users have a lot of information to share with each other. If files to be shared are not controlled, the overloading of information will hinder the sharing activity. Consequently, we propose to select sharable files according the users’ interests. Users can specify their interests to receive/provide information reactively. Users’ interests can also be automatically determined by using association rules and by analysing their social networks. SAMi has been deployed in a simulated environment and over real devices interconnected by Bluetooth. From the evaluations that have been made, we have observed that SAMi has a very good potential to serve nomadic users to share information according
