With the rapid progress of wireless technology, mobile users can retrieve multiple real-time data with portable devices from mobile service centers. Providing deadline guarantees for queries over mobile environments is a challenging problem due to real-time data arrival rates and time-varying data contents. In this paper, we propose a prediction-based(More)
In this paper composite mobile environments, modeled by overlap service areas are taken for performance analysis of a wireless multiple channel link. The accurately approximated Gamma distributions is used to obtain analytical expressions for performance metrics such as average real-time miss rate and outage probability. The equivalent probability(More)
