With current research focus to interconnect the molecular communication environment with external environment, it is imperative to design external devices working on molecular communication schemes to be interfaced with in-vivo molecular network. Recently, efforts have been made to integrate molecular communication with Lab-on-chip (LOC); one of the techniques used in LOC for manipulation and transportation of molecules is Dielctrophoresis (DEP). We propose the use of DEP in molecular communication to maintain in-sequence delivery of molecules. DEP planar electrodes are modeled as relays used in telecommunications. We describe the theoretical system model and analyze the effect of introducing DEP relays in diffusive channel in terms of probability of in-sequence delivery of molecules. Information rate of DEP-based channel is analytically obtained for in-sequence delivery. The numerical results obtained show that the information rate for in-sequence delivery of molecules through diffusive channel increases by 26% if DEP relays are used in the channel. Though the system is sensitive to noise variance, incorporation of DEP relay results in a substantial improvement in the capacity of the channel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
