Energy requirements of error correction codes in diffusion-based molecular communication systems
Publication date: Available online 23 September 2016 Source:Nano Communication Networks Author(s): Yi Lu, Xiayang Wang, Matthew D. Higgins, Adam Noel, Neophytos Neophytou, Mark. S. Leeson Molecular Communications is a promising area with significant potential applications. To enhance the reliability of the transmission process, self-orthogonal convolutional codes (SOCCs) are proposed and investigated with respect to both bit error rate (BER) and energy efficiency. The codes are compared to both an un-coded system and one that employs Hamming codes to show that they can provide a benefit for molecular communication ...

Information theoretic approach in molecular interactions and implications in molecular evolution
Publication date: Available online 22 September 2016 Source:Nano Communication Networks Author(s): Y. Adiguzel Shannon’s information communication theory tells much about the reliable message transmission and has a wide scope of application in communication technologies. The aim of this work is to present the implementation of the information communication theory in the cellular recognition or molecular interaction event models to quantify the message transmission capacities of molecular binding patterns and complexes. It has implications in molecular evolution such that the pattern formation by varied combinations of...

TAB-MAC: Assisted beamforming MAC protocol for Terahertz communication networks
Publication date: Available online 21 September 2016 Source:Nano Communication Networks Author(s): Xin-Wei Yao, Josep Miquel Jornet Terahertz (THz) communication is envisioned as one of the key technologies to satisfy the increasing demand for higher-speed wireless communication networks. The very high path loss at THz frequencies and the power limitations of THz transceivers limit the communication distance in THz networks. Beamforming directional antennas are needed simultaneously in transmission and in reception to communicate over distances beyond a few meters. This results in many challenges at the link layer, whi...

Characterizing terahertz channels for monitoring human lungs with wireless nanosensor networks
Publication date: Available online 19 September 2016 Source:Nano Communication Networks Author(s): Eisa Zarepour, Mahbub Hassan, Chun Tung Chou, Majid Ebrahimi Warkiani We characterize terahertz wireless channels for extracting data from nanoscale sensors deployed within human lungs. We discover that the inhalation and exhalation of oxygen and carbon dioxide causes periodic variation of the absorption coefficient of the terahertz channel. Channel absorption drops to its minimum near the end of inhalation, providing a window of opportunity to extract data with minimum transmission power. We propose an algorithm for na...

Characterization and performance analysis of a chiral-metamaterial channel with Giant Optical Activity for terahertz communications
Publication date: Available online 12 September 2016 Source:Nano Communication Networks Author(s): Anna Maria Vegni, Valeria Loscrí Technology in the THz frequency band has progressed rapidly in the last few years. The THz frequency band offers greater communication bandwidth than microwaves frequencies, and is becoming a standard for nanoscale communications. Traditional channel models for lower frequencies do not take into consideration specific properties as the very high molecular absorption or the very high reflection loss. In addition, in a propagation medium exhibiting a Giant Optical Activity, it is also impor...

Reliability and delay analysis of multicast in binary molecular communication
Publication date: Available online 27 July 2016 Source:Nano Communication Networks Author(s): Zhen Cheng, Yihua Zhu, Kaikai Chi, Yanjun Li Molecular communication is a new and promising communication technology. However, we consider that molecular communication easily suffers from high unreliability and long delay due to the stochastic behavior of the molecules in a biological environment, thus it is essential to investigate the characteristics of reliability and delay in molecular communication. In this paper, we analyze the reliability and delay in multicast topology based on binary molecular communication mo...

Astrocyte –neuron communication as cascade of equivalent circuits
Publication date: December 2015 Source:Nano Communication Networks, Volume 6, Issue 4 Author(s): Fabio Mesiti, Mladen Veletić, Pål Anders Floor, Ilangko Balasingham The propagation of the neural information in the cerebral cortex relies on the transfer of electrochemical impulses and diffusion of neurotransmitter molecules between neuron cells connected in a network through synaptic junctions. In this scenario, increasing interest is growing on the critical role of glia cells, in particular astrocytes, in supporting the neuronal communication. Neuroglias communicate to each other through calcium signaling and...

Realizing Ultra-Massive MIMO (1024 ×1024) communication in the (0.06–10) Terahertz band
Publication date: June 2016 Source:Nano Communication Networks, Volume 8 Author(s): Ian F. Akyildiz, Josep Miquel Jornet The increasing demand for higher bandwidth and higher speed wireless communication motivates the exploration of higher frequency bands. The Terahertz (THz) band (0.06–10 THz) is envisioned as one of the key players to meet the demand for such higher bandwidth and data rates. However, the available bandwidth at THz frequencies comes with the cost of a much higher propagation loss. Due to the power limitations of compact solid-state THz transceivers, this results in very short communication dist...

An optimal decoding algorithm for Molecular Communications systems with noise, memory, and pulse width
Publication date: Available online 16 July 2016 Source:Nano Communication Networks Author(s): Xiayang Wang, Yi Lu, Matthew D. Higgins, Mark S. Leeson Molecular Communications (MC) is a promising paradigm to achieve message exchange between nano-machines. Due to the specific characteristics of MC systems, the channel noise and memory significantly influence the MC system performance. Aiming to mitigate the impact of these two factors, an adaptive decoding algorithm is proposed by optimising the symbol determination threshold. In this paper, this novel decoding scheme is deployed onto a concentration-based MC sys...

Pulse interspersing in static multipath chip environments for Impulse Radio communications
Publication date: Available online 6 June 2016 Source:Nano Communication Networks Author(s): Albert Mestres, Sergi Abadal, Ignacio Llatser, Eduard Alarcón, Heekwan Lee, Albert Cabellos-Aparicio Communications are becoming the bottleneck in the performance of Chip Multiprocessor (CMP). To address this issue, the use of wireless communications within a chip has been proposed, since they offer a low latency among nodes and high reconfigurability. The chip scenario has the particularity that is static, and the multipath can be known a priori. Within this context, we propose in this paper a simple yet very effi...

Real-time observation of bacterial gene expression noise
Publication date: Available online 24 March 2016 Source:Nano Communication Networks Author(s): Olga Anufrieva, Adrien Sala, Olli Yli-Harja, Meenakshisundaram Kandhavelu The mRNA variability in the single cells attributes to random periods of transcription bursts. The cell cycle possesses a global role in affecting transcriptional output. By expressing this process as a communication system at the nanoscale, this transcription output often accounts for the gene expression noise, and this quantifies the promoter activity. However, current stochastic models ignore the fact that gene expression noise is affected no...
