Abstract: Focusing on the bandwidth limitation of transmission between Internet and WSN (wireless sensor network), a multi-core embedded gateway was designed. The gateway was designed using dual-ported memory CY7C026 as the public memory block, ATmega128(L) as the processor module, RTL8019AS as the full-duplex Internet controller, and CC2420 RF chip as the wireless communication module. Nut/OS was utilized to reduce network protocol. Using multiple chips for parallel processing, seamless link could be enforced between Internet and WSN. The experimental results show that the system can provide high stability and improve the transmission bandwidth.
