Ubiquitous resource polymer layer is organized the ubiquitous resource of isomery, shields the isomerism that ubiquitous resource provides equipment.Support IPv6 and wireless telecommunications, introduce the 6LoWPAN technology, and carry out the wireless telecommunications of low-power consumption based on the IEEE802.15.4 standard.To the processing that unitizes of off-gauge lightweight IPv6 data, convert 6LoWPAN IPv6 packet the IPv6 packet of standard into through ubiquitous network gateway middleware, the IPv6 service of standard is provided for upper layer application.
The 6LoWPAN data conversion that ubiquitous network pass middleware goes out the ubiquitous resource transmission of isomery is the IPv6 data.The wireless transmission of ubiquitous resource adopts the 6LoWPAN technology, and the IPv6 message is compressed slicing transmission, and it can be run on the IEEE802.15.4 agreement effectively.
The transport layer protocol that uses in the ubiquitous resource node protocol stack is a udp protocol, and this moment, UDP datagram was compressed to the form that is fit to the 6LoWPAN transfer of data equally.Owing to reasons such as performance, efficient and complexity, the transport layer in the lightweight IPv6 addressing is not used Transmission Control Protocol.The ICMPv6 agreement is mainly used in control messages, as ICMP reset, purpose is unreachable and neighbor discovery messages.
Standard I Pv6 and the format conversion of simplifying IPv6 are positioned at the border in 6LoWPAN territory, i.e. ubiquitous network gateway, and the ubiquitous network gateway need connect the communication network that uses standard I P agreement, comprises a standard I Pv6 protocol stack.Simultaneously, ubiquitous network gateway middleware is responsible for handling the conversion between 6LoWPAN and the standard I Pv6, and 6LoWPAN neighbours' discovery feature, and the realization heterogeneous wireless network is found and disposed automatically and serve for the upper strata provides unified IPv6.
The professional ability of the differentiation that the professional ability polymer layer is unified, the ubiquitous resource of management (handle the concrete ability of using in upper strata, comprise hardware structure and software logic), the isomerism of shielding wireless device (RFID, sensing equipment, wireless network node etc.).Ubiquitous resource authentication and access control middleware through in the service resources comprehensive management platform carry out authentication, mandate, management to ubiquitous resource, for upper layer application provides stable ubiquitous resource and reliable access mode.
As shown in Figure 3: the professional ability polymer layer is made up of following components: application entity, application server, service capability server, service resources comprehensive management platform framework.
Service capability server is used to provide business interface, a series of basic service functions that this type API can the access service server be provided, as set up or discharge route, with user interactions, send user message, set QoS rank etc.Service provider can call to realize different service them according to the different service logic.
Framework server is used to provide framework interface, and all application programs, at first just need be registered on framework server if will call service resources comprehensive management platform interface with professional.Framework server provides essential safe, management to support to business interface, like service registry and discovery, authentication, service order, Integrity Management etc.

2) adopt the 6LoWPAN technology that data are carried out packing, and carry out the forwarding of IPv6 packet through the 2.4G radio band based on the IEEE802.15.4 agreement.
3) the ubiquitous network gateway receives the 6LoWPAN packet, with its IPv6 packet that resolves to standard, go forward side by side walking along the street by.The ubiquitous network gateway is by realizing that any PC that has relevant ability also can serve as the role of ubiquitous network gateway through embedded Linux system.
2, professional ability polymerization
When 1) inserting first, the ubiquitous network gateway sends the request of access to the service resource management platform, and the service resources comprehensive management platform arrives the ubiquitous network gateway according to ubiquitous state of resources loopback authenticating result in the service capability server.Otherwise turn to 4)
2) whether the ubiquitous network gateway allows this resource to insert according to the Authentication Response decision of service resources comprehensive management platform, if allow, then sends the user to ubiquitous resource and inserts response.
3) ubiquitous resource is after receiving that the user inserts response; Send affirmation to the service resources comprehensive management platform and insert message; Service capability server is preserved relevant authentication, the access information of ubiquitous resource, and in the service resources comprehensive management platform, safeguards ubiquitous resource state information.
4) the service resource management platform transfers to application server with application data, and application server is used to service aggregating and generated platform transmission data.
3, service aggregating
1) receives the data that lower floor sends; The content that is provided by application server has 3 types usually; Be respectively data type, applied logic type and user interface type; Correspondence provides data, applied logic function and GUI respectively, the retrieval of data for ease, and the supplier can externally provide the content of oneself through the Web agreement usually.
2) service aggregating is used the generation platform and is sent initial interface to the user, and the latter sends the content of calling with after the retrieval renewal.These call and can directly mail to the third party source or beam back initial server from the user, and initial server is as the agency of third party's content.
3) service aggregating is used and is generated the polymerization that platform is served; The polymerization methods of content is divided into two kinds; The one, directly use the dynamic content generation technique of server end; Realize the application program of similar traditional Web like JSP, PHP or Ruby, the 2nd, directly in user interface, generate through client script or applet.
4) with patterned mode to the user appear application program and with user interactions takes place, show rich UI ins conjunction with the Ajax technology, and use is in position carried out self from the asynchronous content that retrieves of multiple source.
