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

Abstract

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.

Mobile Molecular Communication Through Multiple Measurements of the Concentration of Molecules

“…This type of random mobility may disturb the desired behavior or operations of bio-nanomachines [27]- [37] or can improve the performance of communication under specific settings [38]- [40]. Transmitter and receiver bio-nanomachines may also move directionally, such as is seen in chemotactic cells [41], and directional motion of bio-nanomachines may be useful in developing specific molecular communication mechanisms [42]- [46] or employed in developing practical applications [5], [47]- [53].…”

Modulation and Signal Detection for Diffusive-Drift Molecular Communication with a Mobile Receiver

“…Available studies on MMC systems mainly concentrate on the design of modulation schemes [18][19][20][21] and signal detection schemes [22][23][24][25][26][27][28][29][30][31][32][33]. Regarding the modulation schemes, available works mainly consider FMC systems and cannot be applied to MMC systems directly.…”

“…Regarding the signal detection schemes for MMC systems, available works can be classified into two categories: energy-based signal detection schemes [22][23][24][25] and sampling-based signal detection schemes [26][27][28][29][30][31][32][33]. In energybased signal detection schemes, the receiver first accumulates the number of molecules absorbed by the receiver in a time period and then conducts the signal detection by comparing the calculated number with the predefined threshold of the number of molecules [34].…”

“…With the scheme, the activities of nanorobots can be controlled for a target searching. To also address the problem of target searching, the authors in [27] considered an unbounded MC system with a mobile receiver moving at a variable velocity.…”
