The effect of two receivers on broadcast molecular communication systems

摘要

Molecular communication is a paradigm that utilizesudmolecules to exchange information between nano-machines.udWhen considering such systems where multiple receivers areudpresent, prior work has assumed for simplicity that they do notudinterfere with each other. This paper aims to address this issueudand shows to what extent an interfering receiver, RI, will have anudimpact on the target receiver, RT, with respect to Bit Error Rateud(BER) and capacity. Furthermore, approximations of theudBinomial distribution are applied to reduce the complexity ofudcalculations. Results show the sensitivity in communicationudperformance due to the relative location of the interferingudreceiver. Critically, placing RI between the transmitter TX and RTudcauses a significant increase in BER or decrease in capacity
