Abstract
Molecular communications (MC) is a bio-inspired paradigm that aims to utilise molecules to exchange information among nano-machines. Given the tiny devices used in a MC system and the feasibility of MC in biological environments, MC can be applied to many applications ranging from the healthcare to manufacturing fields.
In order to better realize these applications in the future, this Ph.D. research is dedicated to the investigation of a more functional, precise and reliable Diffusion-based Molecular Communications (DBMC) system. To achieve this goal, the contributions of this thesis are as follows. Firstly, the point-to-point (PTP) DBMC system with the absorbing receiver model is established and investigated. A study of the accuracy of the analytical channel model is also introduced. Secondly, dependent on different types of the transmitter (TX) and receiver (RX), three different communication scenarios are proposed. Thirdly, to enhance the reliability of the information at RX, the Error Correction Codes (ECCs), as the most prominent technique is employed within the DBMC system to control or correct any errors introduced during the transmission process. Fourthly, due to the limitation of the power budget of the nano-machines, the energy efficiency of the system is also taken into account. Finally, a two-receiver broadcast DBMC system is established with an absorbing interfering receiver (RI) and an absorbing target receiver (RT). By analysing the performance of the communication link between TX and RT (target communication link), the impact of the positions of RI on RT is studied.
This study indicates that the application of ECCs does enhance the performance of PTP DBMC systems. In addition, the encoder and decoder design, and the BER performance are shown to be the two primary factors for selecting the most suitable ECC for the application. Finally, considering a two-receiver broadcast DBMC system with absorbing receivers, the existence of RI does affect the performance of the target communication link which is crucial result for the field moving forward.
