In this paper, the authors explore the problem of supporting efficient access to social media contents on social network sites for mobile devices without requiring mobile users to be online all the time. They propose and implement a broker/proxy based architecture that stages data at a broker/proxy, and selectively downloads to the mobile device only those contents that have a high likelihood of being viewed. The system determines the relevance of social media updates that continuously arrive (e.g., Facebook friend updates) for each user. Using knowledge of this relevance and current network/system conditions, they develop scheduling algorithms that determine which social contents are sent to the devices.
