Research on resource allocation strategy of industrial wireless heterogeneous network based on IEEE 802.11 and IEEE 802.15.4 protocol

With the rapid development of wireless communication technology, its flexibility, low cost, easy to deploy features make more and more industrial applications began to deploy industrial wireless network. Industrial wireless networks typically use ISM bands defined by the International Telecommunication Union (ITU-R), which is an open band and therefore we need to consider the resource allocation problem among different wireless network systems. In this paper, we will analyze the resource allocation problem between industrial wireless heterogeneous networks based on IEEE 802.11 and IEEE 802.15.4 protocols in detail, and propose a radio resource allocation system model and a multi-dimensional resource allocation strategy (MRAS) to meet the different business requirements of industry, simultaneously, improve the utilization of wireless network resources.
