Abstract
The study of Molecular Communication(MC) is more and more prevalence, and channel model of MC plays an important role in the MC System. Since different propagation environment and modulation techniques produce different channel model, most of the research about MC are in horizontal direction,but in nature the communications between nano machines are in short range and some of the information transportation are in the vertical direction, such as transpiration of plants, biological pump in ocean, and blood transportation from heart to brain. Therefore, this paper we propose a vertical channel model which nano-machines communicate with each other in the vertical direction based on pure diffusion. We rst propose a vertical molecular communication model, we mainly considered the gravity as the factor, though the channel model is also affected by other main factors, such as the ow of the medium, the distance between the transmitter and the receiver, the delay or sensitivity of the transmitter and the receiver. Secondly, we set up a test-bed for this vertical channel model, in order to verify the difference between the theory result and the experiment data. At last, we use the data we get from the experiment and the non-linear least squares method to get the parameters to make our channel model more accurate.
Highlights
Nowadays, modern telecommunication system conveys most information with electrical or electromagnetic signals
Nariman et al elaborate on the horizontal flow assisted propagation of molecular communication in a long range, but discusses little about the short range of MC based on pure diffusion
We propose a new channel model, which looks like the following Fig. 2, when in a vertical situation, the receiver can receive the peak value [7] of the information molecules, which is very effective for communication, and in biological, the information molecules spread for every direction, and vertical diffusion is one of the common phenomenon, nutrition is transmitted in bloods of human or animals and pheromones are transmitted in plants, both are in this direction sometimes, it’s necessary to research it
Summary
Modern telecommunication system conveys most information with electrical or electromagnetic signals. The use of wireless communication inside networks of tunnels, pipelines, or salt water environment, can be very inefficien [1] As another example, with the dimensions of the transmitter and receiver become smaller and smaller, electromagnetic communication is extremely challenging because of constrains such as the ratio of the antenna size to the wavelength of the electromagnetic signal [2]. The receiver detects and decodes the information encoded in these particles.molecular communication signals are biocompatible, and require very little energy to generate and propagate. These properties makes chemical signals ideal for many applications, such as biomedical application, environment application, where the use of electromagnetic signals are not possible or not desirable.
