Design and implementation of gateway based on Zig Bee wireless sensor networks

Design and realization scheme of sink node in Zig Bee wireless sensor networks is proposed.The embedded CPU ARM966E-S is the core of sink node,which has the uC/OS—Ⅱ embedded operation system,the interface of GPRS model with TCP/IP and wireless transfer model CC2420.Experiment results show that the gateway works well.The needs of the lowpower and real-time can be met.
