Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement

IET Communications, EarlyView., 2022
Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Broadcasting in geometric radio networks

Journal of Discrete Algorithms, 2007
AbstractWe consider deterministic broadcasting in geometric radio networks (GRN) whose nodes know only a limited part of the network. Nodes of a GRN are situated in the plane and each of them is equipped with a transmitter of some range r. A signal from this node can reach all nodes at distance at most r from it but if a node u is situated within the ...

Online Broadcasting with Network Coding [PDF]

2008 Fourth Workshop on Network Coding, Theory and Applications, 2008
Consider a source broadcasting M packets to N receivers over independent erasure channels, where perfect feedback is available from the receivers to the source, and the source is allowed to use coding. We investigate offline and online algorithms that optimize delay, both through theoretical analysis as well as simulation results.
