MOBILE ROUTER FOR SUPPORTING NETWORK MOBILITY OF SENSOR NETWORK BASED ON 6LOWPAN OR ZIGBEE NETWORK COMMUNICATING WITH IPV6 NODE

摘要

A mobile router for supporting network mobility of a sensor network based on 6LoWPAN(IPv6(Internet Protocol version 6) over LoWPAN(Low-Rate Wireless Personal Area Network)) and a Zigbee network communicating with an IPv6 node is provided to support NEMO(Network Mobility) through a NEMO protocol although an IPv6 sensor node of a communication network or a Zigbee device does not have mobility. When a sensor network including 6LoWPAN-based sensor nodes or a Zigbee network including Zigbee devices move from a home agent of an IPv6 network to an external agent, a network layer(22) provides NEMO of the sensor network or the ZigBee network. An application layer(23) allows the sensor network and the IPv6 network to interwork, and combines or disassembles IPv6 packets transmitted and received between the sensor nodes of the sensor network and the IPv6 network. A MAC/PHY layer 24 includes an Internet interface providing mobility of the sensor network or the Zigbee network while communicating with the IPv6 network, a 6LoWPAN interface allowing communication between the sensor nodes of the sensor network, and a Zigbee interface allowing communication between Zigbee devices of the Zigbee network.
