Title:
RESOURCE ALLOCATION METHOD ORIENTED TO COEXISTENCE OF MULTIPLE LINEAR TOPOLOGY INDUSTRIAL WIRELESS NETWORKS
Document Type and Number:
WIPO Patent Application WO/2020/181827
Kind Code:
A1
Abstract:
The present invention relates to wireless network resource allocation technology, and specifically relates to a resource allocation method oriented to the coexistence of multiple linear topology industrial wireless networks. The present invention takes the problem of the coexistence of multiple TDMA-based linear topology industrial wireless networks into consideration, and comprises three parts, i.e. a scheduling delay lower bound analysis, an inter-network resource allocation algorithm and an intra-network resource allocation algorithm. In the method, when a delay lower bound is analyzed and a resource allocation algorithm is designed, an overall scheduling delay and a resource utilization rate are taken as measurement indexes, and an optimal node combination is selected in each slot in order to occupy as many channel resources as possible, thereby improving the resource utilization rate and reducing the overall scheduling delay.
