Design and implementation of uSD card based mobile context data collection and reporting system
基于uSD卡的移动情境数据采集和汇报系统的设计与实现*

This paper presented a uSD card based mobile context data collection and reporting system.Mobile devices used uSD card to communicate with external sensor nodes,and reported the collected internal and external context data to the remote context repository.It proposed a centralized context data sensing and reporting schedule algorithm to eliminate the redundancy among the context data from different mobile devices and improved the collection accuracy by using the collaboration of mobile devices.To handle the...
