We consider quantum multicast networks in which quantum states generated by multiple sources have to be simultaneously delivered to multiple receivers.

We study the approximability of multidimensional generalizations of three classical packing problems: multiprocessor scheduling, bin packing, and the knapsack problem.

Currently available in-house communication channels have been identified as suitable for broadband data communication.

While existing research shows that feedback-based congestion control mechanisms are capable of providing better video quality and higher link utilization for rate-adaptive packet video, there has b

We consider a finite-field model for the wireless broadcast and additive interference network (WBAIN), both in the presence and absence of fading.

An upper bound is established on the usefulness of noisy feedback for the interference channel (IC). The bound is based on the Hekstra-Willems dependence-balance arguments for two-way channels.

The purpose of this note is to present some very simple instances of non-computable functions. Beyond their simplicity, these examples throw light upon the following basic point.

The wireless/cellular communications network is composed of a complex set of interconnected computation units that form the mobile core network.
