Characteristics of ZigBee network topology.
Type
Typical characteristics
Credibility (%)
Safety (0-1)
Star topology
Including a coordinator and multiple terminal devices, the network structure is easy to maintain and has good real-time performance, but there is only one data transmission path, the coordinator may affect the transmission of network data, which can be used in data transmission small scene
99.6
0.9
Cluster topology
The structure is complex, and the network can be transmitted in a multi-hop form; it has the performance characteristics of self-organization and self-coordination
99.5
0.89
Mesh topology
The information is sent in time, the stability is good, and the storage space required is large. At the same time, the cost of maintaining the network is more than more expensive, it can be used in places where the designed ZigBee network is more complicated
