Abstract

The technology of sensor devices and networks is evolving rapidly with significant advances in size, processing power, memory, and energy efficiency. In addition, the cost of sensors is constantly decreasing making it possible to use large quantities of these sensors in a wide variety of important applications in environmental, military, commercial, health care, and other fields. In order to monitor certain types of infrastructures. Many of these applications involve lining up the sensors in a linear form, making a special class of these networks which are defined in this work as Linear Sensor Networks (LSNs). In a previous paper, we introduced the concept of LSNs along with a classification of the different types of LSNs, a sample of their applications and the motivation for designing specialized protocols that take advantage of the linearity of the network to enhance their communication efficiency, reliability, fault tolerance, energy savings, and network lifetime. This paper presents a distributed topology discovery algorithm for a hierarchical two-level LSNs. New definitions for important structure and design parameters are introduced. The proposed protocol allows the nodes to construct an ordered list of the nodes in the network which can be used to create an efficient routing table. In addition, it would be useful for simplifying, and enhancing the reliability and robustness of the routing process by taking advantage of the linear alignments of the nodes. Furthermore, the protocol does not require the nodes to have location detection capabilities such as GPS, which would lead to a more complex design and higher cost of the sensor nodes.
线性传感器网络的分布式拓扑发现算法
传感器设备和网络技术正在迅速发展,在尺寸、处理能力、内存和能源效率方面取得了重大进展。此外,传感器的成本不断降低,使得在环境、军事、商业、医疗保健和其他领域的各种重要应用中大量使用这些传感器成为可能。以便监控某些类型的基础设施。这些应用中有许多涉及以线性形式排列传感器,使这些网络成为一类特殊的网络,在本工作中定义为线性传感器网络(lsn)。在之前的一篇论文中,我们介绍了lsn的概念,并对不同类型的lsn进行了分类,给出了它们的应用示例,以及设计利用网络线性度来提高其通信效率、可靠性、容错性、节能和网络寿命的专用协议的动机。提出了一种分层两级lsn的分布式拓扑发现算法。介绍了重要结构参数和设计参数的新定义。该协议允许节点构建网络中节点的有序列表,该列表可用于创建高效的路由表。此外,通过利用节点的线性排列,它将有助于简化和增强路由过程的可靠性和鲁棒性。此外,该协议不要求节点具有GPS等位置检测功能,这将导致传感器节点的设计更复杂,成本更高。
