Scheduling for Efficient Data Broadcast over Two Channels

As wireless computer networks grow more popular, we are faced with the problem of providing scalable, high-bandwidth service to a growing number of users. In the wireless domain, "data push" promises to provide superior performance for many applications [1]. The broadcast domain that is typical of wireless communication is very effective in distributing information to large audiences. Work has been done to schedule data broadcast from a server to many clients using the broadcast disk model [3]. However, little of it has looked at methods for more than one channel. We examine a simple two-channel broadcast model and present some interesting scheduling results for this model.
