【摘要】：相比传统网络,泛在网中设备数量众多,种类繁杂,且许多数据源网络长期处于无人值守的工作状态。泛在设备的存储和计算能力相比传统网络也更加有限,当前,大多数数据源网络之间一般彼此孤立,不能够与更大范围内的互联网应用和用户进行交互和通信,设备的所提供的服务没有得到充分利用,因此不利于无线泛在业务环境下的产业发展。将泛在网中广泛存在的物融合进与用户更为亲近的互联网,屏蔽设备间的差异,扩展设备的服务范围和服务能力,以实现人与物、物与物之间泛在交互的信息模式,需要为它们的接入方式设计一套易于实施、可以被广泛接受的聚合和开放架构,以达到促进新型业务生成和创新的目的。本文的研究内容主要包含以下几个方面：对比分析了泛在设备与传统网络中设备的差异、泛在业务环境下基于物与环境的应用模式和传统的垂直型应用模式的不同,由此总结出泛在业务环境下能力汇聚与开放架构平台的设计目标。在此基础上,设计了一种低耦合、可扩展的能力汇聚与开放系统架构。开放的平台架构提供了能够使泛在环境中大量的感知层网络以可扩展的方式聚合进平台的框架机制和接入协议,并提供开放统一且易于访问的接口供应用系统使用,支撑用户参与应用研发,使它们能够充分利用到感知设备在泛在环境中提供的上下文信息生成智能化的应用。提出了一种泛在业务环境中数据源网络节点的地址自动配置方法。该方法主要适用于基于IEEE802.15.4的树形拓扑网络,地址的分配方案具有分布式协作的特点,具有较好的可扩展性。根据数据源网络的通信和应用需求,网络中节点的地址分为三个层次,分别为节点的局部地址、网内地址、全网地址,对于泛在网中数据源网络的多类通信需求具有较好的适应性。此外,在节点的网内通信过程中,网内地址能够较为简洁直观的提供路由功能。为了验证所提出的能力汇聚与开放系统架构和可扩展地址分配方案的可行性和有效性,本文最后从项目背景、需求分析、系统结构和特点等方面来介绍了一种能力汇聚与开放演示系统的实现与部署过程。该项目为国家科技重大专项“新一代宽带无线移动通信网”中“基于Web的无线泛在业务环境体系架构、关键技术研究与演示验证”的一部分。
[Abstract]:Compared with traditional network, ubiquitous network has a large number of devices, complex types, and many data source networks are in unattended working state for a long time. The storage and computing capability of ubiquitous equipment is more limited than traditional networks. At present, most of the data source networks are generally isolated and can not be used in a wider range of Internet applications. Interaction and communication with users, the services provided by the equipment are not fully utilized, so it is not conducive to the development of the industry in the business environment. The ubiquitous objects in the pan network are integrated into the Internet which is closer to the users, shielding the differences between devices, expanding the scope of service and service capacity of the equipment to realize people The interactive information mode between objects and objects, objects and objects needs to be designed for their access to a set of easy to implement, widely accepted aggregation and open architecture to achieve the purpose of promoting new business generation and innovation.
The research contents of this paper include the following aspects:
The difference between the equipment of the ubiquitous equipment and the traditional network is compared and analyzed. The difference between the application mode based on the object and the environment and the traditional vertical application mode in the business environment is different. From this, the design goal of the capability converging and open architecture platform in the ubiquitous business environment is summed up. On this basis, a low coupling and extensible energy is designed. The open platform architecture provides a framework and access protocol that enables a wide range of awareness layer networks to converge into the platform in an extensible manner, and provides open, unified and accessible interface supply systems, supporting users to participate in application research and development so that they can fully benefit Intelligent devices are generated by using context information provided by sensing devices in ubiquitous environment.
An automatic address configuration method for data source network nodes in a ubiquitous business environment is proposed. This method is mainly applied to a tree topology network based on IEEE802.15.4. The address allocation scheme has the characteristics of distributed collaboration and has good scalability. According to the communication and application requirements of the data source network, the address of the node is addressed. It is divided into three levels, the local address of the node, the internal address of the network and the full network address, which has good adaptability for the multi class communication requirements of the data source network in the pan network. In addition, the internal address of the network can provide the routing function more succinctly and intuitively in the network communication process.
In order to verify the feasibility and effectiveness of the proposed capability aggregation and open system architecture and extensible address allocation scheme, this paper introduces the implementation and department process of a capability convergence and opening demonstration system from the project background, requirement analysis, system structure and characteristics. "Web based wireless ubiquitous business environment architecture, key technology research and demonstration" is part of the new generation broadband wireless mobile communication network.
