Dispatching communication method and device in industrial wireless sensing network

Abstract

The invention discloses a dispatching communication method in an industrial wireless sensing network and aims at realizing the dispatching communication and the resource distribution in the industrial wireless sensing network. The method comprises the following steps that the updated transmission route information of an industrial wireless sensing network route is obtained; a downward management route from a gateway to node equipment is selected according to the transmission route information; one management link in the downward management route is selected according to the direction of the selected downward management route; time slots are reserved according to preset intervals, and a plurality of available time slots are determined; and whether channels in the available time slots are idle or not are sequentially inquired according to the time slot sequences and the channel sequences in the time slots, if so, the channels in the time slots are distributed to the selected management link, and if not, whether the channels in the available time slots are idle or not are sequentially inquired according to the time slot sequences and the channel sequences in the time slots. The invention also discloses a dispatching communication device in the industrial wireless sensing network.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method and device for dispatching communication in an industrial wireless sensor network. Background technique [0002] Industrial wireless technology is a new wireless communication technology in the 21st century, which is oriented to short-range and low-speed information interaction between devices. It is suitable for use in harsh industrial field environments. It has technical features such as low energy consumption and real-time communication, and has the advantages of good scalability and low installation and maintenance costs. It is a functional extension of the existing wireless technology in the direction of industrial applications. [0003] In the prior art, for scheduling communication problems in traditional multi-hop wireless networks, the network is usually modeled as a multi-objective optimization problem, and a particle swarm optimization (PSO) or heuri...
