Note: Classic communication algorithms that are based on continuous signal communication are not applicable and for WNSNs, time domain short pulse modulation techniques (OOK-TS: Keying Off-On) are used. 

Therefore, these techniques are used especially in cases such as frequency detection systems as well as the Internet of Things. Wave as information carriers similar to classical communications. However, due to the severe shortage of resources and the quantum effects of materials, classical methods can not be applied directly in the field of nanotechnology. Therefore, it is necessary to use new materials and techniques. 

^{Nano-devices are connected at frequencies of about 1.0 to 10 terahertz. Due to the severe limitations of nano-devices in terms of size and energy, the production of high-tech signals at terahertz frequency is not operational. In a molecular telecommunication system, the transmitter sends information by chemical molecules called information molecules, and after propagation in the environment, it is received by the telecommunication receiver and decoded. Telecommunication theories play a special role in modeling, analyzing and designing molecular telecommunication systems.}

^{A nano-network is  a nano- scale communication network between nano-devices. Nano-devices  face certain challenges in performance  due to limitations in the ability to process power management . Therefore, these devices are expected to perform simple tasks that require different and new approaches.  In nano-telecommunications  , different molecules give unique sound signals in relation to the properties of the molecules. There are several nanotechnology technologies that require the use of external excitation and measurement to work. Wireless communication between nano-networks and micro and macro devices and equipment can meet this need. The molecular method is to send and receive information encoded in the molecule While electromagnetic communication is the sending and receiving of  electromagnetic radiation from various nano  -devices, these methods include the molecular method and the electromagnetic method are among the wireless methods  .} 

Conclusion: 

Classic communication ounces based on continuous signal communication cannot be implemented and time domain short pulse modulation (OOK-TS: Keying Off-On) techniques are used for WNSNs.
