Recent Advancements in Molecular Communication among Nanomachines

Nanotechnology is an emerging field which provides opportunities in a vast range of areas. A nanomachine is an integrated device having nanoscale dimensions that can perform very simple tasks. However, it can be made to perform more complicated tasks provided these devices have means of communication. At these small sizes traditional electromagnetic waves are unable to perform their designated work. Hence some alternative means of communication need to be explored; Molecular Communication being one. In this paper, the concept of molecular communication and nanonetwork is introduced which uses biological molecules as information carriers. Molecular communication is a biologically inspired communication scheme in which the information is encoded onto molecules, which are then transmitted to the environment and reach the receivers which react chemically to the molecules and decode the information. This paper provides key concepts, architecture and potential applications of molecular communication.
