A Generalized Air-Cache Design For Efficiently Broadcasting On Multiple Physical Channels
Air cache; Data broadcast; Mobile computing; Scheduling
In limited and asymmetric bandwidth environments such as wireless networks, push technology can be used to allow a large number of mobile users to access the shared data. Most of the today's designs assume that the server disseminates data on only one physical channel. In this paper, we focus on the problem of broadcasting data over multiple physical channels that cannot be coalesced into fewer high-bandwidth ones. Specifically, we propose a novel scheduling scheme called Generalized Broadcast Technique (GBT) which can adapt the content of the broadcasts according to the client mobility and demand patterns. Theoretical foundations and performance evaluation are also provided to substantiate the near-optimality and to assess the advantages of GBT.
