Abstract
Disclosed is a network interworking system and method. That is, a header size is minimized through a fragment of an IPv4 packet based IP packet and a header compression and it is implemented such that the IPv4 is loaded in an IEEE 802.15.4 MAC/PHY packet having a small payload, so that it is possible to efficiently transmit an IPv4 packet by using an IEEE 802.15.4 based WPAN. Further, various applications can be executed using the IPv4 while using an IEEE 802.15.4 technology, which is a low power communication technology, in a mobile device.
