Networking method and wireless communication device of a hybrid access mode multi-hop network

Abstract

The invention discloses a networking method of a multi-hop network with hybrid access modes. The network comprises three kinds of logic nodes consisting of gateway nodes, relay nodes and terminal nodes, wherein the terminal node and the gateway node perform communication by establishing direct connections or indirect connections, the access mode of accessing the gateway node by the direct connection is different from the access mode of accessing the gateway node by the indirect connection; and furthermore, the different access modes can be used when the relay node in the network accesses the gateway node, the relay node accesses the upper-level relay node, the terminal node accesses the relay node, or the terminal node directly accesses the gateway. According to the method, the hops of the multi-hop network are allowed to use different access modes instead of the traditional single access or connection mode adopted by a traditional mesh network, wide area network coverage and access of lots of connections based on the multi-hop network are achieved, and unnecessary spectrum resource and battery energy consumption overheads are avoided.

Description

technical field [0001] The present invention relates to a networking method for a multi-hop cellular Internet of Things with a hybrid access mode, in particular to a networking method for an Internet of Things cellular with a multi-hop network formed by three logical nodes: a gateway node, a relay node and a terminal node Networking method. Background technique [0002] Mesh Networks is the most common IoT, or multi-hop ad hoc network. Each node in the mesh network can be used as a message forwarding node, and each message forwarding node is called a "hop". The coverage of the mesh network can theoretically be extended infinitely through the increase of nodes or "hops", because newly added nodes can forward data through adjacent "one-hop" nodes, so as to realize the connection with any node in the network communication. In a traditional mesh network or a multi-hop network, a single access method is uniformly adopted between adjacent nodes, or between a downstream node and...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, aiming at the limitations of the traditional multi-hop network and mesh (mesh network) network in the actual application of a single access method in the whole network, especially, for wide coverage, To solve the problem that the unified single access mode of the whole network is not flexible enough to carry a variety of IoT networks with various applications, a hybrid access mode multi-hop cellular IoT networking method and a tree-like multi-hop support method are provided. The wireless communication device of the relay node in the network allows completely different access modes between the upstream and downstream nodes of each hop in a multi-hop network, so that the two types of goals of reducing access overhead and access conflict probability can be achieved in Implemented in different areas of a network or in different applications
