Dissemination of Mutable Sets of Web Objects

Recently there has been increasing interest in the application of broadcast networks as high-bandwidth downstream channels of hybrid asymmetric communication platforms. This interest stems from an increasing number of mobile internet users demanding for high quality services whereas wireless networks still lack in bandwidth substantially. In this paper we introduce a proxy architecture enabling transparent web access via hybrid asymmetric communication platforms. It utilizes so-called data carousels to disseminate web contents via high bandwidth data broadcast networks. A data carousel is a set of data items that is repeatedly broadcast. This concept is also referred to as ‘Caches in the Air’ or ‘Disks in the Air’. Furthermore, we propose different techniques to incorporate updates into the carousel cycle and present an evaluation of the different techniques by means of a simulation study.
