AI Technical Summary

Problems solved by technology

The self-organizing network has a dynamic topology, and the nodes are dynamic and unstable. When an agent is selected for service synthesis, the agent itself may fail, thus losing contact with the request source, resulting in service synthesis failure.

Embodiment Construction

[0049] The following describes the entire implementation method in combination with specific examples.

[0050] In an ad hoc network, node 1 needs to complete a synthetic service S, which is completed by 5 atomic services. It is assumed that each atomic service is executed on a different node.

[0051] Step 1: Node 1's executive agent evaluation and self-organizing network evaluation.

[0052] Node 1 initiates a process of evaluating the executive agent and the self-organizing network, inquires about the status of all neighboring executive agents, selects a number of reference targets, and periodically tests the status of the reference targets to determine the state of the self-organizing network, that is, computing Get the K value that meets the service composition requirements and the μ(CM i )value.

[0053] Assume that node 1 obtains the situation of each candidate execution agent as shown in Table 1.

[0054] Table 1 Information of each candidate execution agent on nod...

Abstract

The invention relates to the self-organization network technology field, in particular to a reliable agent execution method. The method includes the following steps: a request origin understands states and abilities of each execution agent by an execution agent assessment and self-organization network assessment; the execution agent of the request origin is selected, and when the selection of theexecution agent is finished, an compounded service of the request is moved to the execution agent to begin an execution; the execution agent is carried out an execution and an error processing. The invention is able to improve a success rate of the service compounded execution and shorten the time of the service compounded execution. Besides, the invention better fits a dynamic characteristic andinstability of the self-organization network node, thus improving practicality of the service compounded in the self-organization network.

Description

technical field [0001] The invention belongs to the technical field of ad hoc networks, and in particular relates to a method for reliably executing composite services on ad hoc networks. Background technique [0002] Self-organizing network is one of the current research hotspots, and it is also a technical field with promising development prospects. Service computing is also a current research hotspot. Currently, service computing is applied in the wired network field. In the wireless network environment, specific to Service computing in the ad hoc network environment is currently a blank in the world. The present invention involves the intersection of the above two fields. Specifically, when the user gives a request for a combined service on the ad hoc network, the ad hoc The organization network selects the appropriate execution agent to improve the success rate of service execution and the quality of service execution. [0003] Some scholars have proposed an agent exec...
