This paper presents the Mobile Chedar Peer-to-Peer middleware for mobile peer-to-peer applications. The middleware is an extension to the Chedar peer-to-peer network allowing mobile devices to access the Chedar network and also to communicate with other Mobile Chedar peers. Currently, Mobile Chedar uses Bluetooth to connect to Chedar gateway peers, because Bluetooth is now the most widespread short-range radio technology in mobile phones. We also introduce in this paper one example of a Mobile Peer-to-Peer application for cooperative lecture notes taking, which is based on Mobile Chedar.
