Research on Scalable Zigbee Wireless Sensor Network Expansion Solution

Abstract

Zigbee technology has a wide range of applications in constructing wireless sensor networks which can increase the number of nodes in the Zigbee network that can be accommodated and expand the wireless sensor network’s network size and monitoring range. TI’s Z-Stack network protocol stack is used as the carrier for Zigbee technology. On the one hand, the information transfer strategy of the network is improved to increase the capacity of a single network. On the other hand, a multiple Zigbee network cooperative communication scheme is proposed which jointly build a scalable, high-capacity wireless sensor network. Test results on the CC2530 chip show that the actual capacity of a single Zigbee network can be improved and multiple Zigbee networks can be collaborated with each other. It is verified that the scheme not only improves the Zigbee network’s overall capacity, but also can flexibly expand, increase or delete Zigbee network size and capacity.
