Problems solved by technology

[0007] (2) In order to achieve offline analysis, some methods do not mainly focus on efficiency and real-time issues
[0008] (3) All instance points cannot be determined in real time, so the decision of some instance points has to be postponed
This kind of marking and rollback makes the information collection logic of dynamic analysis tightly coupled with the instance identification logic, which makes dynamic analysis too complicated and error-prone

Embodiment

[0069] This embodiment discloses an identification method of an event process instance (abbreviated as an instance) in a WSN program, wherein the WSN program refers to a TinyOS program, that is, a program programmed and run in the TinyOS operating system; events in the TinyOS program are divided into interrupt events And non-interrupt events, the lowest hardware interrupt event triggers the execution of the interrupt processing module (InterruptHandler), and the interrupt processing module can trigger high-level non-interrupt events during execution. The following definitions are made for non-interruption events and interruption events:

[0070] Suppose I is an interrupt event, and IH is the event processing module of I, then there are three definitions as follows.

[0071] Definition 1-1: The event procedure (Event-Procedure) of IH is composed of the static codes of the following three nesC modules: IH, the module called by IH, and the task of IH. Among them, (1) the module ...

Abstract

The invention discloses an event process instance (instance for short) identification method in a WSN program, a medium and equipment. The method aims at examples of interrupt events and non-interruptevents. Firstly, key execution points in an instance are defined, and a data structure is set; according to the embodiment of the invention, when each instruction is executed in the running process of the WSN program, the instance information can be updated according to the key execution point to which the instruction belongs, so that the instance information corresponding to the currently executed instruction is obtained in real time, the instance to which the current instruction belongs is judged, and higher real-time performance is achieved. In the instance recognition process, only several proper key execution points need to be used, no extra system operation hypothesis needs to be made, and therefore universality can be effectively improved. Besides, instance identification is realized by only needing several data structures to dynamically store a small amount of execution point information and track switching of the instances in real time without utilizing a list to store and search a large amount of information, so that the space-time overhead can be obviously reduced by the method disclosed by the invention.

Description

technical field [0001] The present invention relates to the technical field of software testing, in particular to a method, medium and equipment for identifying event process instances (instances for short) in WSN programs. Background technique [0002] The Internet of Things is a major change in the field of information technology. Wireless Sensor Networks (WSN), referred to as WSN, is an important means of sensing things and transmitting data in the Internet of Things. A large number of sensors deployed in the monitored area form a WSN, and these sensor nodes form a multi-hop self-organizing network through wireless communication. These nodes cooperatively perceive, collect and process the monitored object or environmental information, and send it to the monitor through WSN. [0003] As an important part of the Internet of Things (IoT) ecosystem, WSN is increasingly used in various application fields. It can help humans enhance perception, improve health, protect the env...
