Design And Implementation Of ZigBee Wireless Sensor Network Based On CC2530

At present，the wireless sensor network has become a research hotspot around theworld. And ZigBee technology with its low complexity，low cost，low powerconsumption and other advantages，is widely used in wireless sensor network. Thispaper implements a wireless sensor network based on CC2530and ZigBee protocolstack.Firstly，this paper introduces the characteristic，network topolopy and protocolanalysis of ZigBee technology. Secondly，the structure of system is proposed ingeneral，and ZigBee node is designed in hardware based on main chip CC2530andradio frequency chip CC2591. Then it describes ZigBee protocol stack，discusses thesoftware flow charts of coordinator，routing node and sensor node，and establishes asensor network in mesh topology. Finally，the established network is tested by serialdebugging tools，and the test emphasized on the network construction，the node net andthe data transmission of sensor node. In addition，in order to detect the performance ofnetwork，the distance between two nodes is also tested.Experimental results show that sensor node can transmit information of monitoringregions to coordinator and a sensor network in mesh topology is achieved.
