In existing mobile content service systems, the study is quite rare on automatic situation-service rule construction. Hence, a method is proposed that the semantic association rules between situations and preferences are built by quantitative frequent marked lattice. Different recommendation rules can be extracted along multi-dimensional context routes from this lattice structure. It is propitious...
Wireless data broadcast is very suitable for delivering information to large user population. In this paper, we concentrate on data scheduling algorithm over multiple channels in mobile computing environments. First, we formulate the average expected delay of multiple channels considering data items' access frequencies, variable length, and different bandwidth of each channel. Second, we propose a...
Femtocell is an effective solution to improve indoor coverage for cellular networks, where short-range and low-power Base Stations (BSs) called Femto BSs are deployed in small areas (e.g., buildings). We propose the Femto Private Branch Exchange (FPBX) to concentrate the traffic of the Femto BSs in a specific area, such as a campus or an enterprise with central or distributed locations. Through the...
