Calcium Signaling in Mobile Molecular Communication Networks: From a Multimedia View

Molecular communications provide an opportunity to understand the complex mechanisms in living individuals. In this work, we employ the calcium signaling among a group of mobile cells to study the multi-modality behavior of mobile molecular communication networks. We study such behavior from a multimedia view by using the experience of traditional communication networks. In the beginning, we employ a random walk model to study the stochastic mobility of biological cells and dynamic property of cellular networks. Then, we propose a mathematical model to illustrate how calcium signals are generated and propagate in mobile networks. In addition, we propose a multimedia theme to study molecular communications. In this regard, we discuss two transmission forms of calcium signaling, namely concentration transmission and waveform transmission. Further, a simulation is executed to illustrate the patterning of calcium signal waveforms and the results indicate the performance is restrained by environmental factors. The results also exhibit the performance differences of two transmission forms and validate the discussed properties of our proposed multimedia theme.
