Abstract
A network communication system includes a ZigBee network being defined based on IEEE 802.15.4, a plurality of IP (Internet Protocol) networks being defined based on IP, and a plurality of gateways available for protocols of the ZigBee network and the IP networks, wherein the plurality of IP networks is connected to the ZigBee network via the plurality of gateways, and a ZigBee frame that is based on the network layer of ZigBee is transmitted in the network communication system, the ZigBee frame storing an IP packet that is based on IP in a part of the ZigBee frame. The gateway includes a hop-limit control section for decrementing a hop number of a packet that passes through the gateway while regarding the ZigBee network as one hop in the IP network.
