摘 要：this paper presents the design and realization of wireless sensor network gateway nodes based on s3c2410 Processor.And introduced the design of gateway hardware and software.Also introduced the implementation method of software.A new data transmit protocol was designed to eliminate the differences between ZigBee protocol and TCP/IP protocol,and this paper also designed a data transmit management module and data communicate module.This gateway can convert the data between ZigBee wireless sensor network and internet.This gateway has a good extensibility.
