Channel modeling and achievable data rate for 1-D molecular communication in bounded environments

Abstract

In this paper, we propose the analytical propagation model for diffusive molecular communication in an one-dimensional bounded environment, and determine available data rate a given limit of interference. Molecular is promising solution applications when typical electromagnetic not available. However, due to randomness molecule movement, it challenging analyze channel communication. Taking into account impact absorbing boundary vessel-like channel, time-varying distribution releasing molecules. Accordingly, derive hitting probabilities information separately reach receiver or boundary, present impulse response at time t. Moreover, under same consider duration between transmissions binary modulation system level inter-symbol Our analysis shows that, certain degree interference, can be expressed as 2Dαth2/S2, where S distance D diffusion coefficient αth2 corresponding index interference degree. The authenticity our are verified via simulations.
