Embodiment Construction

[0037]image 3 Shown is the traditional service discovery method. Two nodes establish a physical connection through a wireless channel, realize node discovery based on the link layer, establish a routing relationship through the network layer, and then initiate the application layer to synchronize the service catalog to achieve inter-node communication Service discovery, you need to complete access to the service catalog>Get the address of the node where the service is located>Steps such as accessing the node where the service is located to obtain the service, the whole process requires multiple interactions. Limited by low-quality wireless network conditions, such as the narrow bandwidth and unstable connection of the wireless connection, it will cause problems such as a certain node to occupy more resources when accessing other nodes, time-consuming access, and high error probability.

Abstract

The invention provides a service ad hoc network method based on service discovery data synchronization, and the method comprises the steps: extracting service description information needed by servicenetworking discovery as service discovery data, combining the service discovery data with networking data of a wireless communication network, synchronizing the service discovery data with the networking data of the wireless communication network between nodes, and after the wireless network completes the ad hoc network, the node can discover the service provided by each node in the network according to the synchronized service discovery data so as to realize service discovery and calling and realize the ad hoc network of the service level. Based on the method, low-consumption and high-reliability synchronization of the service information among the multiple nodes under the wireless network can be realized, quick discovery of the service among the multiple nodes is realized, the problemsof complex synchronization steps, more invalid data and the like existing in a traditional service directory synchronization mode are avoided, and the method is more suitable for a low-bandwidth communication scene of the wireless network.

Description

Technical field[0001]The invention relates to the field of data information systems, in particular to a service self-organizing network method based on service discovery data synchronization.Background technique[0002]In a system oriented to SOA (Service-Oriented Architecture), various functional units are split to form services with specific functions. These services are connected through interfaces and protocols to form a system. At present, the discovery between services is generally achieved through a service catalog. The description information of various services is registered on the service catalog. A certain service can discover other services in the system through the service catalog and call it through the service description information.[0003]Under the condition of multiple nodes in the wireless network, if a node in the wireless network accesses other nodes through a service directory, it will cause problems such as occupying more resources, taking a long time to access, ...
