Data Collection Protocol for Sensors Networks based on Molecular Communications

We discuss a data collection protocol for sensor networks with mobile sinks based on diffusion-based molecular communications (DMC). In DMC, nodes are communicating with each other by emitting molecules which diffuse throughout the fluidic medium: molecules are information carriers. In our data collection protocol for DMC, the symbol time is dynamically adjusted based on the distance between the sink and sensors to deal with the inter-symbol interference problem and two modulation techniques are combined to handle the multiple access problem.
