Zigbee modular Star topology of wireless transmission protocol is the simplest of the three types of topology , Including a Co-ordinator(zigbee Central coordinator ) Network nodes and multiple enddevice(zigbee Module terminal ) Network nodes . Every endevice(zigbee Module terminal ) Network nodes can only be connected to co-ordinator(zigbee Module coordinator ) Network node link communication , other endevice(zigbee terminal ) Network nodes cannot be linked . If you need to be in two endevice( terminal ) Network nodes communicate with each other , Must be linked co-ordinator(zigbeee Module coordinator ) Network nodes receive and forward information .
Zigbee There is a defect in the complementary structure of modular wireless transmission technology ： The wireless transmission mode between network nodes has only one unique route .Co-ordinator（ The coordinator ） The status of network nodes may become the influence point of the whole network . The network implemented by star network topology does not need to use Zigbee Network layer wireless transmission protocol of the module , because IEE802.15.4 The protocol layer has been implemented on the basis of star topology , But this adds more work for developers in the application layer , Including information receiving and forwarding .
