Abstract:To solve the issues of low-price, low-power and real-time in transmission process of the wireless network, this paper designed the low-power wireless hardware circuit which is based on the MSP430 and CC2420. In this paper,we take many measures in hardware, software and network topology optimization to obtain this performance. By taking experimental verification, the system can collect the signal in time. Besides, in most industry environments.we can meet the requirement of the low-power These nodes can manage the site by ways of networking technology and routing protocol, with the advantages of monitoring industry site real-timely, optimizing the network structure and reducing power consumption..
