Analysis of ARQ protocols for bacterial quorum communications
Publication date: Available online 4 January 2016 Source:Nano Communication Networks Author(s): Chenyao Bai, Mark S. Leeson, Matthew D. Higgins Quorum sensing (QS) is used to describe the communication between bacterial cells, whereby a coordinated population response is controlled through the synthesis, accumulation and subsequent sensing of specific diffusible chemical signals called autoinducers, enabling a cluster of bacteria to regulate gene expression and behavior collectively and synchronously, and assess their own population. As a promising method of molecular communication, bacterial populations can be p...

Role based shared memory access control mechanisms in NoC based MP-SoC
Publication date: Available online 2 December 2015 Source:Nano Communication Networks Author(s): Arnab Kumar Biswas, S.K. Nandy Security is becoming one of the main aspects of Multiprocessor System-on-Chip (MP-SoC) design. Software attacks, the most common type of attacks, mainly exploit vulnerabilities like buffer overflow. This is possible if proper access control to memory is absent in the system. In this paper, we propose three hardware based mechanisms to implement Role Based Access Control (RBAC) model in Network-on-Chip (NoC) based MP-SoC. According to our knowledge, our solutions are the first attempts to i...

A discussion on molecular absorption noise in the terahertz band
Publication date: Available online 23 November 2015 Source:Nano Communication Networks Author(s): Joonas Kokkoniemi, Janne Lehtomäki, Markku Juntti This paper focuses on molecular absorption noise caused by molecular absorption in the higher frequency bands, such as THz band ( 0.1 – 10 THz). This transmission induced noise has been predicted to exist in the THz band, since the conservation of energy requires the conservation of the absorbed energy in the medium. There exist multiple models for the molecular absorption noise. Most of them focus only on the transformation of the absorbed energy directly into an...

Cellular communication via directed protrusion growth: Critical length-scales and membrane morphology
Publication date: Available online 14 November 2015 Source:Nano Communication Networks Author(s): Haijiang Zhang, Anna Kim, Shijun Xu, Gavin D.M. Jeffries, Aldo Jesorka We investigated the growth of cell protrusions from adherent HEK 293 cells and their capability to bridge cytophobic Teflon® AF microgaps, establishing a critical length scale, beyond which cells cannot probe free space. For this purpose, we employed a photolithography-based surface fabrication strategy for producing micropatterned substrates composed of glass and the amorphous polymer Teflon® AF. Cell protrusions growing from HEK 293 ce...

Lightweight, self-tuning data dissemination for dense nanonetworks
Publication date: Available online 4 November 2015 Source:Nano Communication Networks Author(s): A. Tsioliaridou, C. Liaskos, S. Ioannidis, A. Pitsillides A nanonetwork comprises a high number of autonomous nodes with wireless connectivity, assembled at micro-to-nanoscale. In general, manufacturing and cost considerations imply that nanonetworking approaches should have minimal complexity, ideally without sacrifices in network coverage. The present paper studies a networking approach fit for static, dense topologies comprising numerous, identical, computationally-constrained nodes. These attributes are especial...

A statistical model for the MIMO channel with rough reflection surfaces in the THz band
Publication date: Available online 3 November 2015 Source:Nano Communication Networks Author(s): Zheng Xu, Xiaodai Dong, Jens Bornemann Based on the reflection properties of rough surfaces, we propose a statistical multiple-input multiple-output (MIMO) antenna system in the terahertz (THz) band for nanocommunications. First, our analysis of scattering from a rough surface indicates that the reflection from a single surface can be a cluster of rays. Secondly, a new MIMO model for THz communications is proposed. In this model, the number of multipaths is highly dependent on the roughness of the reflecting surfaces....

Effects of non-flat interfaces in human skin tissues on the in-vivo Tera-Hertz communication channel
Publication date: Available online 3 November 2015 Source:Nano Communication Networks Author(s): Ke Yang, Qammer Hussain Abassi, Nishtha Chopra, Max Munoz, Yang Hao, Akram Alomainy The influence of the interface type between the epidermis and dermis layers within the human skin tissue is investigated in this paper by introducing two models with different interfaces (i.e., 3-D sine and 3-D sinc function). By comparing the power loss of both models, it is evident that the common flat model is sufficient in case of electromagnetic communication links studies within the human tissue without the need of complica...

Astrocyte–neuron communication as cascade of equivalent circuits
Publication date: Available online 28 August 2015 Source:Nano Communication Networks 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 ...

A queueing-theoretical delay analysis for intra-body nervous nanonetwork
Publication date: Available online 12 August 2015 Source:Nano Communication Networks Author(s): Naveed A. Abbasi, Ozgur B. Akan Nanonetworks is an emerging field of study where nanomachines communicate to work beyond their individual limited processing capabilities and perform complicated tasks. The human body is an example of a very large nanoscale communication network, where individual constituents communicate by means of molecular nanonetworks. Amongst the various intra-body networks, the nervous system forms the largest and the most complex network. In this paper, we introduce a queueing theory based delay ana...
