Problems solved by technology

However, the process and thread concurrency model currently used in general embedded systems is too expensive for extremely limited tiny nodes.
In conclusion, the design of the concurrency model is a core and difficult problem for the operating system of the small node of the wireless sensor network sensor

Embodiment Construction

[0026] The purpose of the present invention is to provide an operating system for small sensor nodes of a wireless sensor network. The operating system implemented according to this system meets the special needs of wireless sensor networks: such as limited hardware resources, the adequacy of the hardware resources ranges from extremely small to the general resources of our ordinary embedded devices, and generally needs to give full play to the limited resources To maximize the utilization rate, it is also necessary to ensure the real-time performance of the system response, and at the same time meet the diverse needs of applications, and provide good support for those applications or tasks that do not require real-time performance. Neither the event-driven concurrency model nor the process and thread concurrency models of general embedded devices can meet the requirements.

[0027] Task scheduling is the core issue of the operating system and the key to solving task concurren...

Abstract

The invention provides a novel concurrent model, specifically a micro-program concurrent model, for meeting special requirements of an operating system of small nodes of a wireless sensor network, and solves key mechanisms of task concurrency, synchronous mutex and task to task communication by implementing the scheduling based on the micro-program concurrent model. In consideration of the problem of limited resource and the feature of concurrency of a sensor system, the micro-program is a task, is an execution process of one or a series of open program segments and is one of basic scheduling unit of the operating system. The micro-program must be continuously executed in the program segment and is not allowed to enter a blocked state, but the process between the program segments can be blocked. By configuring the tasks supporting different grades, different types of resource limited sensor hardware can be effectively adapted.

Description

[0001] technical field [0002] The invention relates to an operating system of a wireless sensor network sensor small node supporting a micro-program, and belongs to the technical field of computers. Background technique [0003] In the context of ubiquitous computing, wireless sensor networks have greatly shortened the distance between people and the physical world, and can collect information about the physical world anytime and anywhere, and exercise proper control. At the same time, the emergence and development of wireless sensor networks is of great significance to promote ubiquitous computing. After decades of development, wireless sensor network technology and applications have gradually become popular, and have played a very important role in many fields. However, due to the current highly application-related problems, most wireless sensor systems have no operating system and no software platform. Although the application system has accumulated some experience in...
