. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone. 1.

. In this paper, we examine two broadcast structures in the context of a distributed detection problem whose inputs are statistically dependent. Specifically, we develop a suboptimal approach to maximize the Kullback-Leibler divergence over a set of binary quantization rules. Our approach not only leads to simple

problem. We exploit the structure of this problem and derive simple and fast iterative algorithms that provide the optimum transmission policies for the multiple-access channel, which can easily be mapped to the optimal broadcast channel policies.

. This optimization problem is referred to as minimum-energy routing. While minimum-energy unicast routing can be solved in polynomial time by shortest-path algorithms, it remains open whether minimum-energy broadcast routing can be solved in polynomial time, despite of the NP-hardness of its general graph version

(noncooperative scenario). This system can be considered as a combination of two broadcast channels (from the transmitters ’ points of view) and two multiple-access channels (from the receivers ’ points of view). Taking advantage of both perspectives, two signaling schemes for such a scenario are developed

between clients and servers. In previous papers, we have proposed Broadcast Disks as a model for structuring the repetitive transmission of data in a broadcast medium. Broadcast Disks are intended for use in environments where, for either physical or application-dependent reasons, there is asymmetry

In many distributed-memory parallel computers and high-speed communication networks, the exact structure of the underlying communication network may be ignored. These systems assume that the network creates a complete communication graph between the processors, in which passing messages

in a deterministic setting. We first analyze the structural properties of the optimal transmission policy in a two-user broadcast channel via the dual problem of maximizing the departure region by a fixed time

In this position paper, we present an efficient algorithm for performing a broadcast operation with minimal cost in structured DHT-based P2P networks. In a system of N nodes, a broadcast message originating at an arbitrary node reaches all other nodes after exactly N-1 messages. We emphasize

Broadcasting is a problem of information dissemination described in a group of individuals connected by a communication network, where one individual has an item of information and needs to communicate it to everyone else. This communication pattern finds its main applications in the field
