(3) An association relationship model between the capability factors is defined.

In step 2, integrated networking and modeling are carried out on heterogeneous communication resources based on “VTP-VHP”, which are namely a virtual terminal processer and a virtual host processer. Various communication resource factors are classified into a backbone network, a tactical network and an edge network according to a technical system, a throughout capacity, a response time and other indexes, wherein the backbone network comprises a satellite trunk, a broadband microwave, laser communication, and other factors, the tactical network comprises a JTIDS data link, a V / U data link, and other factors, and the edge network comprises an inter-flight data link, a maritime formation cooperative data link, and other factors. Resource decoupling, resource opening and cross-platform dynamic restructuring are carried out on the task system of the platform and the communication resource factor, so that the platform without enough or suitable communication resources can access the network by “channel borrowing”, and the problem that the Internet of Things system realizes ubiquitous interconnection based on the heterogeneous network is solved, which specifically comprises the following steps. (1) Resource decoupling: a technology of “the virtual terminal processer - the virtual host processer (VTP-VHP)” is designed, the VTP (Virtual Terminal Processer) centrally indicates various communication resources to dock with the task systems of the platforms, and the VHP (Virtual Host Processer) centrally indicates the task systems of the platforms to dock with the communication resources, so as to realize resource decoupling of the communication resources with the task systems of the platforms. The VTP-VHP are a computing entity loaded with an address and a behavior, may communicate with the outside through message delivery, and may concomitantly execute an action. (2) Resource opening: a unified bearer network of an IP protocol is constructed for a backbone node with a broadband communication resource, the VTP-VHP are linked in a cross-platform manner, so as to support opening of the communication resources of the platforms to the outside, and an association relationship between multiple independently operated tactical / edge networks can be established by interconnecting the backbone nodes, so as to support cross-network task coordination. (3) Demand-based aggregation: when one platform has multiple categories of communication resources (such as a node A shown in FIG. 1), the communication resources are virtualized into “one network” by the “VTP-VHP”, so as to provide a single interface and a multi-link distribution service of information for the task system of the platform; and when one platform does not have enough or suitable communication resources, the backbone network may be utilized to log on to other platforms to access the required tactical / edge network by “channel borrowing”, so as to realize the dynamic restructuring of the task system of the platform and the communication resources. (4) Network management: because mobile platform networking exists for one or a series of tasks in a specific region, after the tasks are completed, the platform is landed and the network is dissolved, so that dynamic network planning and management are needed, which are undertaken by the network management system in the networking service capability factor, thus carrying out planning and designing, definition with software, dynamic adjustment and independent maintenance on the association relationship between various factors. The integrated networking model of the heterogeneous communication resources based on the “VTP-VHP” is shown in FIG. 1. In step 3, an incremental integrated architecture of unified networking service-oriented system / platform is designed. Aiming at different systems / platforms of land, sea and air and various communication resources, a general integrated architecture and a modular and combinable networking service unit are designed, and the problem of unified networking service of the Internet of things system is solved by an incremental embedded integrated mode, which specifically comprises the following steps. (1) The general integrated architecture is constructed. A unified communication resource integrated architecture is constructed for various systems / platforms according to a three-layer structure of “application, service and resource”, wherein the application layer consists of one or more task systems on the platform; the service layer consists of functional units, such as the VTP, the VHP, an IP gateway and security exchange; and the resource layer consists of various broadband and narrowband communication resources.

(3) Incremental integrated application is realized. According to a difference of the capability factors of the platforms and different types of the communication resources possessed, networking service modules are selected as needed and the modules are combined into the networking service product adapted to the specific platform, and the task system of the platform and the communication transmission resources are integrated by the incremental embedded integrated mode. A horizontal aggregation of the networking service units of all platforms is equivalent to forming a “wide-area bus”, which refers to realizing ubiquitous interconnection of the Internet of Things system. The incremental integrated architecture of the unified networking service-oriented system / platform is shown in FIG. 2. In step 4, a networking service operation mechanism of an information-centered Internet of Things system is designed. A traditional address-centered communication mode is changed, an information-centered multi-topological structure integrated cross-layer networking protocol is designed to form the networking service operation mechanism, so as to meet cross-platform sharing of the communication resources in the Internet of Things system and a requirement of automatic distribution of information between multiple networks, which comprises the following steps. (1) A task community is planned and designed. When multiple systems / platforms need to be connected together for a certain task to be operated cooperatively, task requirement decomposition is carried out by the network management system to decompose a total task into multiple sub-tasks, so as to form multiple independent task groups, the association relationship (NR) between the corresponding task network and the platform factor is established through network planning and designing, which is loaded as the initialization parameter (M-S) of the networking system, and the initialization parameter is distributed to the networking service unit of each platform. (2) The task community is defined with software. After the networking service unit of the platform receives the initialization parameter (M-S) of the networking system, the initialization parameter is distributed between internal modules, wherein the VTP converts the initialization parameter into the relationship (PR) between the task system of the platform and the communication transmission factor of this platform / other platforms, which is maintained independently during network operation, and the VHP converts the initialization parameter into the relationship (NR) between the communication transmission factor and this platform / other platforms, which is maintained independently during network operation, relevant information of the broadband transmission factor is extracted by the IP gateway, and address management and mapping are carried out, so as to generate a unified IP bearer backbone network. (3) An integrated cross-layer networking protocol is designed. According to an information distribution protocol: the VTP is a unified entrance for the task system of the platform to access various networks, when the task system needs to exchange information with members in the community, the information is sent to the VTP in a unified manner, the VTP decides which link / links of which platform are used for addressing / broadcasting according to information of the relationship PR, and attaches a “link code” label to the information to send to the VHP of the corresponding platform, and the VHP executes a corresponding link interface protocol according to the “link code”, so as to realize automatic distribution of the information between multiple networks. According to an information receiving protocol: the VHP is a unified entrance for transmitting information of multiple networks to the task system of the related platform, the information landing from any network is sent to the VHP in a unified manner, the VHP decides the task system of which platform the information is sent according to information of the relationship NR, and sends the information to the VTP of the corresponding platform by addressing, and the VTP carries out deduplication, integrity integration, and the like on the information. According to an information forwarding protocol: the VTP sends all the integrated information to the task system of the platform, forwards broadcast information in the integrated information to other links according to a preset forwarding and filtering rule, automatically generates a machine response to the addressed information, and returns by an original path, thus improving reliability of wireless transmission.
