Abstract

This paper proposes a joint localization and synchronization method in the presence of a 3-D (cuboidal-bounded) channel. Many biologically relevant structures, such as epithelium cell membranes, tissues, and blood vessel networks (particularly capillaries), can be effectively modeled as 3-D systems. Localization and synchronization among nanomachines play an important role in the optimal transmission rate, information exchange, and collaboration among nanomachines. Clock synchronization without localization or localization without clock synchronization affects the accuracy of the system. However, the existing methods consider that nanomachines are already synchronized for localization and vice-versa. Hence, the proposed method considers a combined model for location parameters, clock offset, and clock skew. Unlike the existing method, we consider this combined model in bounded environments, which are relevant for long-range molecular communication where released molecules need to be confined within a certain range to optimize power efficiency. However, deriving an analytical channel characterization for a constrained domain is challenging. We provide an analytical equation for the probability distribution function of the propagation delay of the molecules, taking into account the presence of both single and multiple absorbing walls.

有吸收和反射边界的立方体有界扩散通道中的联合定位和时钟同步

本文提出了一种存在三维（立方体边界）通道时的联合定位和同步方法。许多生物相关结构，如上皮细胞膜、组织和血管网络（尤其是毛细血管），都可以有效地模拟为三维系统。纳米机械之间的定位和同步对纳米机械之间的最佳传输速率、信息交换和协作起着重要作用。没有定位的时钟同步或没有时钟同步的定位都会影响系统的精度。然而，现有的方法认为纳米机器在定位时已经同步，反之亦然。因此，建议的方法考虑了定位参数、时钟偏移和时钟偏斜的组合模型。与现有方法不同的是，我们考虑的是有界环境中的组合模型，这与远距离分子通信有关，因为释放的分子需要限制在一定范围内，以优化功率效率。然而，为受限领域推导分析性信道特征具有挑战性。我们为分子传播延迟的概率分布函数提供了一个分析方程，同时考虑了单个和多个吸收壁的存在。

期刊介绍： The proposed journal, called the IEEE Transactions on Network Science and Engineering (TNSE), is committed to timely publishing of peer-reviewed technical articles that deal with the theory and applications of network science and the interconnections among the elements in a system that form a network. In particular, the IEEE Transactions on Network Science and Engineering publishes articles on understanding, prediction, and control of structures and behaviors of networks at the fundamental level. The types of networks covered include physical or engineered networks, information networks, biological networks, semantic networks, economic networks, social networks, and ecological networks. Aimed at discovering common principles that govern network structures, network functionalities and behaviors of networks, the journal seeks articles on understanding, prediction, and control of structures and behaviors of networks. Another trans-disciplinary focus of the IEEE Transactions on Network Science and Engineering is the interactions between and co-evolution of different genres of networks.
