Channel Switching in Molecular Communication Networks through Calcium Signaling

Switching is an indispensable functionality in traditional computer networks. Inspired by computer networks design, this paper investigates the switching functionality for molecular communication networks. In particular, we design channel switches for molecular communication among biological cells through calcium signaling. First, we extend mathematical models of calcium signaling by incorporating gating models of gap junction channels. Second, we show how channel switches may be designed based on the mathematical models, with numerical results demonstrating the switching functionality. Further, we discuss design issues for practical application of channel switches. This paper shows through mathematical modeling and numerical experiments that channel switches are feasible and indicates that complex molecular communication networks may be designed using channel switches.
