Method of supporting multi-homing in a ubiquitous sensor network

摘要

Method of Supporting Multi-homing in a Ubiquitous Sensor Network The present invention provides a method for supporting multi-homing in a ubiquitous sensor network. In the method, a sensor network gateway sends a configuration request to a sensor network controller, the configuration request being for querying whether a sensor network governed by the sensor network gateway supports multi-homing; then, the sensor network gateway receives a configuration file from the sensor network controller, the configuration file being for indicating whether the sensor network supports multi-homing; when the sensor network supports multi-homing, a binding update message is sent to the sensor network controller, wherein the binding update message comprises an identifier of the sensor network and an indicator for indicating that the sensor network supports multi-homing. By adopting the solution of the present invention, the sensor node or sensor network is enabled to simultaneously access to the Internet in a multi-interface manner.

1. A method of supporting sensor network multi-homing in a sensor network gateway, comprising:
sending a configuration request to a sensor network controller, wherein the configuration request comprises a query as to whether a sensor network governed by the sensor network gateway supports multi-homing; receiving a configuration file from the sensor network controller, wherein the configuration file comprises an indicator that indicates whether the sensor network supports multi-homing; when the sensor network supports multi-homing, sending a binding update message to the sensor network controller, wherein the binding update message comprises an identifier of the sensor network and an indicator for indicating that the sensor network supports multi-homing.
