Abstract

Early detection of abnormalities within the human body is crucial for timely medical intervention. In-body nano communication using mobile nanosensors is a possible solution to this task. To facilitate early system evaluation, simulation tools are essential. This work focuses on the communication between in-body nanosensors and an on-body gateway, aiming to assess data transmission efficiency, identify potential challenges, and optimize nanosensor design for practical applications. We introduce BloodVoyagerS(BVS)-Net, an open-source ns-3 module that models the terahertz (THz) communication channel between nanosensors and the external on-body gateway. Building upon existing ns-3 components for wireless links (BVS), BVS-Net provides an interface for intra-body THz communication between nanosensors flowing in human vessels and an on-body computing device. Our module simulates a networking device within each nanosensor, modeling the transmission of binary data through human tissue. The communication channel between nanosensors and the gateway is modeled using the necessary physical propagation properties of blood vessels. On the receiver side, a networking device at the skin level simulates data reception and caching. Our simulation reveals that communication is error-free for nanosensors traveling at a depth less than 400 micrometers. However, deeper within the vessel, noise in the communication link causes the constellation points to disperse in the in-phase axis, leading to errors.
