Wireless Sensor Networks Gateway with Multi-Communication Methods

For the Wireless Sensor Networks (WSNs), gateway equipment connecting with other networks is needed to realize the long distance transmission of the information from the sink nodes. The gateway with only single communication method is difficult to accommodate the practical applications. Therefore, a WSNs gateway by which data can be transmitted with Ethernet, PSTN and GPRS communication methods is designed and implemented. The S3C44B0X MCU of ARM7 series and μClinux embedded operating system are used to construct the gateway. Meanwhile, multithreading technology is utilized to manage the parallel communication.
