摘要: Abstract:
This paper proposed a data broadcasting and searching algorithm called the windmill indexing algorithm (WIA). WIA provides a new data searching method for mobile devices and a novel data scheduling method for broadcast systems, which maintains favorable access latency of broadcast messages and simultaneously conserves mobile device energy. The WIA constructs index and data channels based on the access popularities of broadcasted messages. The index channel guides mobile devices in rapidly locating the nearest position of the desired message. To search for non-popular messages, the index channel leads MDs conduct a linear search directly in data channel. The numerical analysis and simulation results verify that when the difference of access popularities among broadcasted messages is large, the proposed WIA method attains extraordinary performance enhancements regarding energy conservation and access latency.
