Embedded Nano Relay for Intra-Body Network-Based Molecular Communications

Abstract

AbstractWe propose an embedded synthetic relay transport protein (RTP) approach for communication between the external environment (blood vessels) and internal targeted nanonetworks (cells/tissues) within the intra-body network. In fact, we designed a bioengineered relay protein-based facilitated diffusing to be an alternative protein in the case of biological transport proteins (such as protein channels, e.g. Pores) failing. The proposed approach is inspired by the traditional wireless communication system-based relay concept, in which embedded nanodevices known as donor, relay, and acceptor bionanomachine construct a molecular communication system. Fluorescence resonance energy transfer nanocommunications are used to connect the embedded bionanomachines, and the therapeutic drug is transferred in the form of exciton. The performance analysis of the proposed approach is evaluated in terms of channel capacity of RTP as function of intrinsic environmental parameters and the location of the relay between the donor, and acceptor bionanomachines. The numerical results show that the proposed approach improves channel capacity by 16.7% over previous work.
