What are Nanonetworks?
Nanonetworks are a novel and emerging concept in
nanotechnology that involves the interconnection of
nanoscale devices to perform complex tasks. These networks can be composed of nanosensors, nanoprocessors, and nanotransmitters that communicate and collaborate to achieve a specific goal. The communication between these devices can occur through various methods, including electromagnetic, acoustic, or molecular communication.
How do Nanonetworks Work?
Nanonetworks operate on the principle of integrating multiple nanoscale devices to work in unison. Each device in the network has a specific function, such as sensing, data processing, or transmitting information. These functionalities are combined to create a robust system capable of performing sophisticated operations at the nanoscale. The devices communicate with each other through
nanoscale communication protocols, which can vary depending on the application and environment.
