A Framework for Investigating the Performance of Chaotic-Map Truly Random Number Generators
Ahmad Beirami, Hamid Nejati
In this paper, we approximate the hidden Markov model of chaotic-map truly random number generators (TRNGs) and describe its fundamental limits based on the approximate entropy-rat…
Network Compression: Memory-Assisted Universal Coding of Sources with Correlated Parameters
Ahmad Beirami, Faramarz Fekri
In this paper, we propose {\em distributed network compression via memory}. We consider two spatially separated sources with correlated unknown source parameters. We wish to study…
On Lossless Universal Compression of Distributed Identical Sources
Ahmad Beirami, Faramarz Fekri
Slepian-Wolf theorem is a well-known framework that targets almost lossless compression of (two) data streams with symbol-by-symbol correlation between the outputs of (two) distrib…
Discrete-Time Chaotic-Map Truly Random Number Generators: Design, Implementation, and Variability Analysis of the Zigzag Map
Hamid Nejati, Ahmad Beirami, Warsame H. Ali
In this paper, we introduce a novel discrete chaotic map named zigzag map that demonstrates excellent chaotic behaviors and can be utilized in Truly Random Number Generators (TRNGs…
Data Gathering in Networks of Bacteria Colonies: Collective Sensing and Relaying Using Molecular Communication
Arash Einolghozati, Mohsen Sardari, Ahmad Beirami +1
The prospect of new biological and industrial applications that require communication in micro-scale, encourages research on the design of bio-compatible communication networks usi…
A Realizable Modified Tent Map for True Random Number Generation
Hamid Nejati, Ahmad Beirami, Yehia Massoud
Tent map is a discrete-time piecewise-affine I/O characteristic curve, which is used for chaos-based applications, such as true random number generation. However, tent map suffers…
