A method for supporting multi-homing in a sensor network in the Pan
2011
The present invention proposes a method for the pan supports multi-homing in a sensor network. In this method, the sensor transmits a configuration request to the network gateway sensor network controller, the configuration request is used to query whether the network gateway of the sensor network sensor network supports multi-homing; Then, the gateway receives the sensor profile from the sensor network controller the configuration file for indicating whether the sensor network supports multi-homing; when the sensor network supports multi-homing, to the sensor network controller transmits a binding update message, wherein the binding update message contains the identifier of the sensor network, and a sensor for indicating that the network supports multi-homing indicator. According to the present embodiment of the invention, the sensor or sensor network nodes can simultaneously access a variety of ways to interface to the Internet.
