Calcium Signaling in Mobile Molecular Communication Networks

Calcium signaling plays an important role in both physiological activities and engineered applications of molecular communication. Recent experimental studies in biology reveal that calcium signaling is closely related to mobility of biological cells. In this paper, we address communication- related issues of calcium signaling among a group of mobile cells. First, a mobility model of biological cells is established based on experimental studies in biology. Then, the mobility model is integrated with a widely accepted model of calcium signaling. Further, computer simulations are performed using the integrated model to examine the communication-related performance of calcium signaling among a group of mobile cells. A major finding from computer simulations is that there exists an optimal moving velocity of cells to maximize the range of signal propagation in a group of mobile cells.
