【摘要】：物联网正在向着多元化、开放化的方向发展,作为物联网基础的传感网需要为多元化的业务提供基础设施资源以及灵活的资源调度。目前,传感网都是基于特定传感应用部署,存在多厂商异构的特点,造成传感基础设施资源的重复部署现象和资源利用率低。为了解决这个问题,本文将网络虚拟化技术引进到传感网中,用于实现传感基础设施资源的共享。本文在对现有问题分析的基础之上,研究了面向应用的传感网虚拟化的体系结构,在原有传感基础设施层之上构建面向应用的传感虚拟化网络服务层,然后提出一种传感网虚拟化的解决方案。为了实现虚拟化的网络服务层,本文引进简单网络管理协议,用于应用服务器与智能传感网关以及智能传感网关与传感终端节点之间的通信,并结合传感网资源受限的特点,本文对简单网络管理协议进行了轻量化处理和相应的协议拓展。最后,本文对提出的面向应用的传感网虚拟化解决方案进行了设计和实现,主要是智能传感网关和传感终端节点的设计,以及应用分类调度机制以及虚拟抽象层等功能的设计,实现了传感网虚拟化解决方案中资源调度和多传感应用的并存。最后本文搭建了一个实验性的传感网络,并设计了不同的传感应用,通过对比不同应用场景下的传感设施的利用情况,可以看出,传感网虚拟化可以实现传感基础资源的共享,提高资源的利用率。
[Abstract]:Things are moving towards diversification, open direction, sensor networks need as a foundation of things to provide diversified business infrastructure resources and flexible resource scheduling. At present, sensor networks are deployed in specific sensing applications based on characteristics of heterogeneous, causing the sensing infrastructure duplication of resources and resource deployment phenomenon the low utilization rate. In order to solve this problem, this paper will introduce the network virtualization technology in sensor networks, for sharing sensing infrastructure resources. This paper based on the analysis of existing problems, studies the architecture of sensor network virtualization application oriented, in the original sensing infrastructure construction for application layer virtual sensor network service layer, and then presents a solution of sensor network virtualization. In order to realize the virtual network service layer, this paper introduces Jane Simple network management protocol for communication between the application server and the intelligent sensor gateway and intelligent sensor gateway and sensor terminal nodes, combined with the characteristics of sensor networks with limited resources, the light weight and the corresponding agreement to expand on the simple network management protocol. Finally, the sensor network virtualization of application oriented proposed solution program design and implementation, the design is the main gateway and sensor intelligent sensor terminal nodes, design and application of classification scheduling mechanism and virtual abstraction layer function, realizes the coexistence of sensor network virtualization solutions in resource scheduling and multi sensing applications. Finally, this paper builds an experimental sensor network, and the design of the different sensing applications, through the use of facilities, sensing comparison of different application scenarios can be seen that the sensor network virtualization can achieve transfer Share the basic resources and improve the utilization of resources.
