摘要

Nanonetworks will enable advanced applications of nanotechnology in the biomedical, industrial, environmental and military fields, by allowing integrated nano-devices to communicate and to share information. Due to the expectedly very high density of nano-devices in nanonetworks, novel Medium Access Control (MAC) protocols are needed to regulate the access to the channel and to coordinate concurrent transmissions among nano-devices. In this paper, a new PHysical Layer Aware MAC protocol for Electromagnetic nanonetworks in the Terahertz Band (PHLAME) is presented. This protocol is built on top of a novel pulse-based communication scheme for nanonetworks and exploits the benefits of novel low-weight channel coding schemes. In PHLAME, the transmitting and receiving nano-devices jointly select the optimal communication scheme parameters and the channel coding scheme which maximize the probability of successfully decoding the received information while minimizing the generated multi-user interference. The performance of the protocol is analyzed in terms of energy consumption, delay and achievable throughput, by taking also into account the energy limitations of nano-devices. The results show that PHLAME, by exploiting the properties of the Terahertz Band and being aware of the nano-devices' limitations, is able to support very densely populated nanonetworks with nano-devices transmitting at tens of Gigabit/second.
