Network optimization method based on LTE (Long Term Evolution) wireless and ultra-low-power wide-area network Internet of Things wireless convergence

Abstract

The invention relates to the technology field of Internet of Things, and particularly discloses a network optimization method based on LTE (Long Term Evolution) wireless and ultra-low-power wide-areanetwork (LPWAN) Internet of Things wireless convergence. The method comprises the following steps of: introducing a token mode to simplify a complex protocol; adopting a hardware decoding mode to improve the speed of a network protocol conversion; using a caching mechanism to avoid data fragments in the LPWAN network to improve the schedulability; establishing a routing stress model for LPWAN multi-hop communication based on a traditional radio frequency model; regarding the communication route between a source node and all multicast nodes as a multicast tree, wherein the multicast tree with the smallest integrated routing pressure is the optimal path under the constraint condition; determining the optimal number of communication nodes; and establishing a set of access routing alternativepaths between the multicast source nodes and all multicast nodes. According to the inherent relationship between the LTE wireless and the ultra-low-power wide-area network (LPWAN) Internet of Things wireless system, the software/hardware method is used to improve the network convergence tightness, and a wireless network routing node pressure model is established, thereby optimizing the pressure ofrouting nodes, improving the response speed of an important data network, and significantly improving the working efficiency of a wireless network.
