Network Coding applications in molecular communication

Major problems in diffusion based molecular communication are Inter Symbol Interference (ISI), low data rates and limited range of communication. Keeping symbol duration as long as possible leads to avoid ISI may be a solution, but this leads to even further reduced data rates. In order to cope with limited range of communication, using relays is one of the major solution. Relay amplifies the data coming to it and conveys it to target. Network coding is a concept that uses relays not only as a conveyor but also as an encoder to increase spectral efficiency. In this paper enhancements of the diffusion based molecular communication systems is observed using Network Coding. Using the proposed method, two nanomachines that are so far from each other are able to communicate with tolerable ISI and higher data rates.
