Ad-hoc networking and routing method implemented by logical area coordinates for wireless Internet of things

Abstract

The invention discloses an ad hoc networking and routing method implemented by logical area coordinates for wireless Internet of things. The method comprises the following steps: building network connection architecture; marking network connection entities with the logical area coordinates in logical areas; building a routing path of new network connection entities; and maintaining routing tables between adjacent points. In the ad hoc networking and routing method implemented by the logical area coordinates for the wireless Internet of things, node position information is marked on the basis of dynamic logical abstract coordinates relevant to application semantics rather than physical static coordinates. The method can be used in a way of being bound with a plurality of different physical address coordinate systems. Meanwhile, a hybrid routing algorithm based on the logical area coordinates proposed in the method supports routing / forwarding of a hierarchical area, and supports a sparse Mesh topology among different areas at the same time, so that a system topology with a large number of nodes is effectively supported, and the effectiveness of a forwarding path is considered at the same time.

Description

technical field [0001] The invention relates to the technical field of networking and communication methods of a wireless Internet of Things system, in particular to a self-networking and routing method of a wireless Internet of Things using logical area coordinates. Background technique [0002] In IoT applications, most sensor-connected entities are based on wireless connections. These connections have the following characteristics: [0003] 1. The number of Internet connection entities is huge, often reaching thousands / tens of thousands, such as lighting management in residential quarters and enterprise floors; [0004] 2. Due to mobility and short life cycle, network connections are dynamic and temporary; [0005] 3. The network connection has a one-to-many or many-to-many relationship; [0006] 4. The Internet of Things business has a strong location-based feature (Location-based), but indoor sensing equipment does not have a GPS positioning system; [0007] 5. Most...
