On The Efficient Use Of Multiple Physical Channel Air Cache
In limited and asymmetric bandwidth environments such as wireless networks, push strategy can be used to allow a large number of mobile users to access the shared data. Most of today's solutions 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. This introduces new hurdles such as the heterogeneities of channels and data set. We propose a novel broadcast design at the server side, which is aimed at minimizing the response and download times. We also present a caching policy at the client side to further enhance the performance. Theoretical foundations and simulation-based studies are also presented to substantiate the near-optimality and to assess the advantages of the proposed technique.
