Method for providing mobility of device in wireless sensor network based on 6LoWPAN

摘要

PURPOSE: A mobility of a device which moves to a mobility network supporting method in a 6LowPAN(IPv6 Low-power wireless Personal Area Network) based wireless sensor network is provided to support the mobility of the device by separating location information from an identifier of the device. CONSTITUTION: A sensor node transmits a registration request message to a mobile router(S1). The mobile router transmits the registration message to a gateway(S2). The gateway transmits a location update request message to a home mapping server(S3). In case the identifier of a mobile sensor node is not registered in the home mapping server, the home mapping server transmits a search request message to a device management server(S4). The device management server transmits a search response message to the home mapping server(S5).
