Measuring Distance From Single Spike Feedback Signals in Molecular Communication

Distance Estimation Schemes for Diffusion Based Molecular Communication Systems

“…3 show that both the original and simplified estimation schemes taking advantage of the peak time work well in the DMC system. To get the best performance, the TN is required to emit molecules as fast as possible, and the simplified estimation scheme according to (9) can perform as well as the original scheme using (8) if T e is quite small.…”

“…Four distance estimation schemes based on feedback protocols were introduced in [7], subsequently expanded in [8], [9]. The schemes were designed in 2D environments by means of measuring the round-trip time or the fading of the signal amplitude (or frequency).…”

“…Here, the nano-machines measured either the peak concentration or the time interval between the first and second peak to estimate the distance. By using these two schemes, the time cost is significantly decreased compared to [7]- [9], but no intuitive benefit on accuracy is presented. In [11], an approach for bounding the estimation accuracy was described to provide a possible method to evaluate distance estimation schemes.…”

One Symbol Blind Synchronization in SIMO Molecular Communication Systems

“…In [3], based on the assumption of the synchronization, signal detections are proposed for mobile molecular communication. In [4], the nanomachines are assumed to be synchronized for distance estimation by a two-way message exchange protocol.…”

Networking challenges and principles in diffusion-based molecular communication

“…Similarly, receiver nanomachines could release a special type of molecules that would allow transmitters to estimate their distance to potential receivers. Another option to estimate the distance between nanomachines would be to measure the round-trip time of a pulse of molecules released by the transmitter [13].…”
