项目摘要

Fundamentals of Efficient Communication in Wireless Underground Sensor Networks AbstractWireless Underground Sensor Networks (WUSN) is a promising field that will enable a wide variety of novel applications that were not possible with current wired underground monitoring techniques. Compared to the current wired underground sensor networks, WUSN have several remarkable merits, such as concealment, ease of deployment, timeliness of data, reliability and coverage density. Despite its potential advantages, the realization of WUSN is challenging. The main challenge in this area is the realization of efficient and reliable underground links to establish multiple hops and efficiently disseminate data for seamless operation. Furthermore, the propagation characteristics of electromagnetic (EM) waves in soil prevent a straightforward characterization of underground wireless channel. Hence, advanced propagation and multi-path models are required to investigate the effects of soil in underground communication. This research provides advanced models and techniques to completely characterize the underground wireless channel and lay out the foundations for efficient communication in this environment. This model aims to characterize the propagation of EM wave in soil by considering multipath, soil composition, water content, and burial depth. Based on these peculiarities of communication in soil, an optimization framework is developed to characterize cross-layer communication aspects in WUSN. This framework jointly models problems at various protocol layers such as medium access control, routing, and transport in a cross-layer fashion. Moreover, a cross-layer framework is investigated to analyze the effects of various error control techniques and determine the optimal packet size in WUSNs. This optimization framework is based on three main optimization functions in terms of energy consumption, throughput, and resource utilization. Consequently, efficient communication protocols can be developed based on the foundations of the channel model developed in this research and the most efficient error control techniques determined by this framework.
无线地下传感器网络的有效通信基础摘要无线地下传感器网络(WUSN)是一个很有前途的领域,它将使各种各样的新的应用是不可能与当前的有线地下监测技术。与现有的有线地下传感器网络相比,无线传感器网络具有隐蔽性、易部署性、数据的及时性、可靠性和覆盖密度等显著优点。尽管它具有潜在的优势,但WUSN的实现具有挑战性。这一领域的主要挑战是实现高效和可靠的地下链路,以建立多跳和高效传播数据,实现无缝操作。此外,电磁(EM)波在土壤中的传播特性阻止了地下无线信道的直接表征。因此,需要先进的传播和多径模型来研究土壤在地下通信中的影响。这项研究提供了先进的模型和技术,以完全表征地下无线信道,并奠定了在这种环境下有效通信的基础。该模型的目的是通过考虑多径、土壤成分、含水量和埋深来表征电磁波在土壤中的传播。基于土壤中通信的这些特点,开发了一个优化框架来表征WUSN中的跨层通信方面。该框架联合模型的问题,在不同的协议层,如媒体访问控制,路由和跨层的方式传输。此外,一个跨层的框架进行了研究,以分析各种错误控制技术的效果,并确定在WUSN的最佳数据包大小。该优化框架基于能耗、吞吐量和资源利用率方面的三个主要优化功能。因此,有效的通信协议可以开发的基础上,在本研究中开发的信道模型和最有效的差错控制技术,由这个框架确定的基础。
