【摘要】：相比傳統(tǒng)網(wǎng)絡,泛在網(wǎng)中設備數(shù)量眾多,種類繁雜,且許多數(shù)據(jù)源網(wǎng)絡長期處于無人值守的工作狀態(tài)。泛在設備的存儲和計算能力相比傳統(tǒng)網(wǎng)絡也更加有限,當前,大多數(shù)數(shù)據(jù)源網(wǎng)絡之間一般彼此孤立,不能夠與更大范圍內(nèi)的互聯(lián)網(wǎng)應用和用戶進行交互和通信,設備的所提供的服務沒有得到充分利用,因此不利于無線泛在業(yè)務環(huán)境下的產(chǎn)業(yè)發(fā)展。將泛在網(wǎng)中廣泛存在的物融合進與用戶更為親近的互聯(lián)網(wǎng),屏蔽設備間的差異,擴展設備的服務范圍和服務能力,以實現(xiàn)人與物、物與物之間泛在交互的信息模式,需要為它們的接入方式設計一套易于實施、可以被廣泛接受的聚合和開放架構,以達到促進新型業(yè)務生成和創(chuàng)新的目的。 本文的研究內(nèi)容主要包含以下幾個方面： 對比分析了泛在設備與傳統(tǒng)網(wǎng)絡中設備的差異、泛在業(yè)務環(huán)境下基于物與環(huán)境的應用模式和傳統(tǒng)的垂直型應用模式的不同,由此總結出泛在業(yè)務環(huán)境下能力匯聚與開放架構平臺的設計目標。在此基礎上,設計了一種低耦合、可擴展的能力匯聚與開放系統(tǒng)架構。開放的平臺架構提供了能夠使泛在環(huán)境中大量的感知層網(wǎng)絡以可擴展的方式聚合進平臺的框架機制和接入?yún)f(xié)議,并提供開放統(tǒng)一且易于訪問的接口供應用系統(tǒng)使用,支撐用戶參與應用研發(fā),使它們能夠充分利用到感知設備在泛在環(huán)境中提供的上下文信息生成智能化的應用。 提出了一種泛在業(yè)務環(huán)境中數(shù)據(jù)源網(wǎng)絡節(jié)點的地址自動配置方法。該方法主要適用于基于IEEE802.15.4的樹形拓撲網(wǎng)絡,地址的分配方案具有分布式協(xié)作的特點,具有較好的可擴展性。根據(jù)數(shù)據(jù)源網(wǎng)絡的通信和應用需求,網(wǎng)絡中節(jié)點的地址分為三個層次,分別為節(jié)點的局部地址、網(wǎng)內(nèi)地址、全網(wǎng)地址,對于泛在網(wǎng)中數(shù)據(jù)源網(wǎng)絡的多類通信需求具有較好的適應性。此外,在節(jié)點的網(wǎng)內(nèi)通信過程中,網(wǎng)內(nèi)地址能夠較為簡潔直觀的提供路由功能。 為了驗證所提出的能力匯聚與開放系統(tǒng)架構和可擴展地址分配方案的可行性和有效性,本文最后從項目背景、需求分析、系統(tǒng)結構和特點等方面來介紹了一種能力匯聚與開放演示系統(tǒng)的實現(xiàn)與部署過程。該項目為國家科技重大專項“新一代寬帶無線移動通信網(wǎng)”中“基于Web的無線泛在業(yè)務環(huán)境體系架構、關鍵技術研究與演示驗證”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.
