Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] In the present invention, when scheduling and distributing wireless sensor network connections, the middleware has both connection forwarding and connection scheduling functions, and the system structure involved is as follows: figure 1 and figure 2 As shown, the specific implementation process is as follows:

[0027] In order to realize the reasonable scheduling of the wireless sensor network connection by the middleware, it is necessary for the IoT message receiving server to communicate with the middleware, and to inform the middleware of the load capacity and other performance of the message receiving server. In order to maintain the IoT message receiving server table, it is necessary to regularly check whether the IoT message receiving server information is consistent with the message receiving server table. In order to achie...

Abstract

The invention discloses a connection allocation and scheduling method of a sensor network in the Internet of things, and belongs to the technical field of wireless communication technology and wireless sensor networks. The connection allocation and scheduling method of the sensor network includes the steps that communication with a message receiving server of the Internet of things is achieved to obtain information of the message receiving server of the Internet of things, a proper connection allocation and scheduling algorithm is established according to the obtained information of the message receiving server of the Internet of things, and when a wireless sensor network requests to be connected with the message receiving server, the connection is allocated to the proper message receiving server of the Internet of things according to the established connection allocation and scheduling algorithm. By means of the connection allocation and scheduling method of the sensor network in the Internet of things, good operation of a high-concurrency and large-throughput large project of the Internet of things can be achieved; the optimal connection scheduling algorithm can be selected according to the situation of the message receiving server of the Internet of things, and thus the most reasonable load balance of the message receiving server of the Internet of things is achieved.

Description

technical field [0001] The invention relates to wireless communication technology and wireless sensor network technology, in particular to a sensor network connection allocation and scheduling method in the Internet of Things. Background technique [0002] The wireless sensor network is composed of a large number of micro sensor nodes with perception, computing and communication capabilities placed in the monitoring area. Its purpose is to collaboratively monitor, collect and process the information of the monitored objects in the network coverage, and send it to the observation server. These sensor nodes have the characteristics of small size and long use time. The sensing data information collects relevant information of the surrounding environment through the cooperation between network nodes, and after simple data processing, the information is transmitted to the message receiving server by a certain communication method for further processing. analysis and processing. ...
