Parameter study and characterization of wireless nanonetworks through simulation

Abstract

Abstract-Nanowireless electro-magnetic communication networks in the Terahertz band have raised interest in the networking community these very last years. However, if detailed studies have been published on analytical modelling of these networks, no simulation have been run to study in detail the characteristics of the transmission medium. We have designed Vouivre, a standalone nanowireless simulator, which is interfaced with two micro-robots simulator DPRSim and VisibleSim. This paper describes briefly Vouivre and presents first metrics of the communication channel using a communication paradigm called TS-OOK (Time Spread On-Off Keying).

Large scale MEMS robots cooperative map building based on realistic simulation of nano-wireless communications

“…In [5,6] we then implemented nano-communications as a pulse-based mechanism and use a dedicated modeling of the environment to take into account the specificities of both nano-transceivers and terahertz frequency band. Evaluations were conducted on basic test scenarios to get a better grasp of the behavior of nano-communications.…”

“…The lower part of the figure highlights the same situation with a redundancy factor of 3. To study the useful throughput related to the beta parameter, several simulations were conducted on statics nodes in [6]. Figure 9 shows thresholds in function of the number of concurrent senders.…”

“…As explained in [6], the average number of received bits per message, for a given receiver, is calculated using a SCORE given to each concurrent incoming message (See Figure 7). To avoid threshold effects and to statistically smooth the results for all the simulations, a random message acceptance decision function is used.…”

“…But, expanding communication range through wireless links can significantly broaden the scope of possible applications. In previous works, we investigated such possibilities, first adding standard CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) radio to the Claytronics simulation environment [4] and then investigating more specific communications means, through nano-wireless (nano-antennas, terahertz band and pulse based modulation fitting this environment), as seen in [5,6]. Those previous works built the necessary foundations for more complex applications.…”

Going for large scale with nano-wireless simulations

“…Concurrently, for simplicity and feasibility reasons, a simple pulse-based encoding scheme such as Time-Spread OnOff Keying (TS-OOK) [7] is required. In this context, we previously developed Vouivre [4,3], a simulation library. This library aims at simulating nano-wireless communications using the channel model from [6].…”
