Embodiment Construction

[0042] The present invention will be further described below in conjunction with drawings and embodiments.

[0043] XMPP-based wireless sensor network firmware update management method, its management structure is as follows figure 1 shown. The methods supported by the management objects in this figure are shown in Table 1. In this table, the system management objects can support all of the methods and data services, but the device nodes in the network can only support some of the methods and data services. .

[0044] Table I

[0045]

[0046] For the single-point management and multi-point management transmissions in Table 1, they will be introduced separately below.

[0047] (1) Single point management transmission

[0048] Single-point management transmission means that at a certain moment, one manager only manages one node device. In the system where XMPP is applied to WSN, the single-point management transmission is mainly realized through a request-response mecha...

Abstract

The invention provides a wireless sensor network firmware updating method based on an XMPP, and relates to the technical field of wireless sensor networks. According to the wireless sensor network firmware updating method, on the basis of an XMPP series protocol standard, corresponding expansion is carried out on a core protocol of the XMPP; a manager system is designed to be provided with a system management object according to application requirements of an industrial wireless sensor network and by means of characteristics of the object; each equipment node in the wireless sensor network is provided with a firmware updating management object and management of the network is achieved through a mode of operating the management object. The wireless sensor network firmware updating method can effectively guarantee real-time performance of the industrial wireless sensor network and improve overall management quality and efficiency of the network.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to an XMPP-based firmware update method for wireless sensor networks. Background technique [0002] With the rapid development of wireless sensor network technology, its application has also received extensive attention from all walks of life. At present, in the application system of the wireless sensor network, the server and the sensor node contain various firmware programs, and these firmware programs need to be updated under certain circumstances. In order to achieve these goals, the current firmware update function is mainly to install an update tool on each server, and then update the firmware on each server. This firmware update method is not only time-consuming and labor-intensive, but also prone to errors. For example, during the update process, the server often misses updating the firmware. Contents of the invention [0003] The purpose of the present ...
