Periodic time slot allocation method for wireless network

Abstract

The invention provides a periodic time slot allocation method for a wireless network. The method cocmprises the steps of: connecting the plurality of nodes through a wireless network; constructing a time slot parameter set of wireless network nodes and an interval array between time slots of each node; calculating an acceptable total time interval of each node in a wireless network, selecting the node with the minimum acceptable total time interval in the wireless network as a time slot allocation node, further allocating a time slot for each time slot demand of the time slot allocation node, and allocating a time slot for each time slot demand of the remaining nodes except the time slot allocation node for the remaining nodes in the wireless network; and carrying out delay detection and judgment on time slot distribution. According to the method, quantitative calculation and analysis of node parameters during allocation are realized, and fairness can be considered while the allocation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wireless network time slot allocation, in particular to a wireless network-oriented periodical time slot allocation method. Background technique [0002] The rapid development of wireless network technology enables people to access and obtain Internet resources anytime, anywhere, quickly and freely, which has greatly changed communication and life style. With the rise of concepts such as "Internet +" and the Internet of Things, communication is not limited to people and people, but also extends to people and various hardware devices. [0003] Wi-Fi equipment adopts the IEEE802.11 protocol, and the carrier sense and collision avoidance (Carrier Sense Multiple Access / Collision Avoidance, CSMA / CA) mechanism adopted by the MAC layer of the protocol will lead to uncertainty of transmission delay. This problem is particularly prominent in fields that require high real-time performance, such as the Internet of ...

Problems solved by technology

Therefore, the IEEE802.15.4 protocol widely used in industrial control networks obviously cannot meet the design requirements of high-speed and high-real-time performance in hybrid networks in new scenarios.

[0006] Therefore, in the channel time slot allocation of the current Wi-Fi wireless network, there are shortcomings such as low real-time performance and uncertain delay.
