This letter addresses a low‐complexity adaptive wireless data broadcasting system. Specifically, it proposes a way for reducing the computational complexity of the estimation …
Data dissemination via periodic broadcasting considers a set of items, each with a given request probability, size and scheduling cost. The goal is to construct a broadcast schedule …
In wireless push-based systems traffic is asymmetric meaning that the server has much more bandwidth available, as compared to the clients. Since it is often not possible or desirable for …

To provide increasing multimedia broadcast/multicast services (MBMSs), the third generation partnership project modified long‐term evolution release nine documents to …
Waiting time-optimal scheduling of items for broadcasting in wireless environments requires knowledge of their corresponding access probabilities. Feedback mechanisms have been …
The present paper proposes a generalization of the square root rule for optimal periodic scheduling. The rule defines a ratio of item occurrences in a schedule, which minimizes the …
