Molecular communication via diffusion (MCvD) is a new research area that considers the communication using messenger molecules in a diffusive fluidic channel. In this area, various modulation methods have been proposed to overcome the problems in the channel, especially the inter symbol interference (ISI). However, these methods are generally considered and tested for the channels that do not change...
In this paper, a transfer function that models Molecular Communication via Diffusion (MCvD) between a point transmitter and a fully absorbing circular receiver in an unbounded 2-D environment is analytically derived. The analytical derivation of the transfer function of the 2-D channel in MCvD is proposed for the first time in the literature. The transfer function is obtained by solving the molecule...
Communication in the nanoscale is subject to different physical conditions compared to macroscale. This arises the need for constructing alternative communication methods, suitable for the conditions and applications in the desired scale. As one of these methods, molecular communication via diffusion conveys information by utilizing messenger molecules as the information carrier in the channel, rather...
Major problems in diffusion based molecular communication are inter symbol interference (ISI) and low data rates. Keeping symbol duration as long as possible may be a solution, but this leads to even further reduced data rates. In this paper, a novel modulation system that works well in higher data rates is proposed by combining other proposed techniques in the literature. This system relies on encoding...
Major problems in diffusion based molecular communication are Inter Symbol Interference (ISI), low data rates and limited range of communication. Keeping symbol duration as long as possible leads to avoid ISI may be a solution, but this leads to even further reduced data rates. In order to cope with limited range of communication, using relays is one of the major solution. Relay amplifies the data...
