Sensing network control layer, sensing network architecture and construction method thereof

Abstract

The invention discloses a sensing network control layer, a sensing network architecture and a construction method thereof. The sensing network control layer is arranged in a physical network sensing layer; all nodes of an Internet of Things sensing layer communicate with a physical network gateway through the sensing network control layer; the sensing network control layer comprises: a plurality of control nodes; the control nodes are all screened out from the nodes of the Internet of Things sensing layer; the links between the control nodes are all screened ou from the links of the Internetof Things sensing layer; the screening of the control nodes and the links satisfies the following conditions: the energy of each control node is greater than a set energy threshold; the moving speed of each control node is less than a set speed threshold; the total number of control nodes is less than a set number threshold; non control nodes of the Internet of Things sensing layer communicate with the physical network gateway through the control nodes; and if a link is added to the sensing network control layer, the link is connected, and the two nodes of the link are also in the sensing network control layer.

Description

technical field [0001] The invention belongs to the field of Internet of Things and cloud computing, and relates to a perception network control layer, a perception network architecture and a construction method thereof. Background technique [0002] The rapid development of information and communication technology has promoted the development of smart devices such as RFID, Bluetooth and embedded systems. These smart devices can communicate with each other through the network, and then complete tasks such as automatic recording and automatic processing, which leads to the emergence of new services and applications. The concept of Internet of Things (IoT) came into being. At present, a large number of IoT devices are connected to the Internet in different ways. It is estimated that by 2020, the number of smart devices connected through the Internet of Things will reach 50 billion. However, because the current IoT devices are often configured according to their specific appl...

Problems solved by technology

However, the integration of the Internet of Things and cloud computing introduces additional communication overhead, which is not conducive to the development of real-time services in the Internet of Things. At the same time, placing the network controller in the cloud increases the communication delay between nodes and controllers and reduces network performance.
