| The wireless sensor network is located in the perception layer of the ubiquitous network, whichbelongs to the endings of ubiquitous network. It has been widely used in the military, environmentalmonitoring and forecasting, health care, building condition monitoring, urban traffic, largeworkshop and warehouse management, and safe monitoring about airport, large industrial park andso on. With the development of ubiquitous network, the technology o f wireless sensor network willhave great significance in the society and economy of the entire country, even in the lifestyle of thefuture of humanity.One kind of unicast discovery routing algorithm is proposed on the hardware platform ofCC2530based on the analysis of the ke y techonology of ZigBee network. And this algorithm takeslow-power design as the target. According to the characteristics of ZigBee network routing, thealgorithm is designed and implemented from the aspects of routing policy, frame definition andframe processing. And then building network is tested by the pictures of network topology whichobtained by PC software. After that, for the sake of network convergence, the paper carries on theinteroperability between ZigBee network and the Cellular network, and the ZigBee-GPRS gatewayis developed. From the point of the application of the interconnection, application scenarios isanalyzed. Combining with the principles of the ZigBee stack, the feature of GPRS Modemcommunication data protocol and the requirement of the functional applications, the functionalmodules and system are designed, the data protocol is defined, and the processing of the concretedata packets is stated. Finally, the function of the network interoperability is tested and validatedby the serial-port assistant as well as the user hand-held terminal. A large number of test resultsshow that the designed ZigBee-GPRS gateway works stably, and meet the requirements of theinteroperability between the ZigBee network and the Cellular network. |
