D-MoSK Modulation in Molecular Communications
Molecular communication in nanonetworks is an emerging communication paradigm that uses molecules as information carriers. In molecule shift keying (MoSK), where different types of molecules are used for encoding, transmitter and receiver complexities increase as the modulation order increases. We propose a modulation technique called depleted MoSK (D-MoSK) in which, molecules are released if the ...Show More

Deterministic Model for Pulse Amplification in Diffusion-Based Molecular Communication
IEEE Communications Letters
Cited by: Papers (9)
In molecular communication, molecules are used to transmit information from a nanotransmitter to a nanoreceiver. In many molecular communication applications, the primary aim is to send a single pulse to trigger a response at the receiver. As such, the transmitter can emit a “puff” of information molecules that will freely diffuse in a fluidic environment. In free-diffusion-based communication, th...Show More
