Channel Aggregation in Molecular Communication Network Based on Calcium Signal

Abstract

Molecular communication (MC) is a kind of communication technology using biochemical molecules as information carrier. Compared with traditional electromagnetic signal, the signal attenuation of biochemical molecules in the transmission process is very serious. However, in the body area nano-networks, in order to ensure the normal life activities of cells, there is a limit to the concentration of the signal molecules. Communication distance cannot be increased by increasing the concentration of information molecules, simply. Channel aggregation can reduce the concentration constraint and effectively solve the communication distance problem caused by signal attenuation. This paper introduces the molecular communication network about channel aggregation using calcium signal. According to the attenuation regulation of calcium signal, a scheme of channel aggregation is proposed.
