Challenges and Distinctions in Nanonetworks Design

Nanotechnology is a promising research field, which deals with structures, devices, systems and materials creation. Nanotechnology gives the potential of manipulating matter at an atomic and molecular scale, enabling devices development in a scale ranging from one to hundreds of nanometers. Nanonetwork is considered to be a new research branch, which derived from applying nanotechnology in the digital communication field. A nanomachine is the basic functional unit in nanotechnology that can perform simple tasks, like sensing and actuation. A set of nanomachines can perform more complex tasks through communicating and sharing information, and by that, they form a nanonetwork. Different communication techniques are proposed for information exchange among nanomachines. The main research motivation is to emphasize that nanonetworks have different functionalities, environmental rules and objectives, and thus different approaches to system design and problem specifications are needed.
