METHOD FOR NODE IDENTIFICATION AND SERVICE ADVERTISEMENT IN COMMUNICATION NETWORKS

WIPO Patent Application WO/2017/121134

A1

Communication networks and methods for optimized node identification and service advertisement in said networks using a single message procedure are disclosed. The present invention is a mechanism in a 6LoWPAN having at least one sensor node 502, at least one 6LoWPAN router 504, and at least one 6LoWPAN border router 506, for verifying IP address/Host name of said sensor node and updating service provided by said sensor node using at least one neighbor solicitation (NS) message and at least one duplicate address registration (DAR) message. The present invention provides a technique of adding 2 new options, one for carrying host name and another for carrying service advertisement information. The 2 additional options are included in the same set of messages which are used for duplicate address detection. Once, the messages reach the 6LoWPAN border router, the content of these options are parsed and checked for duplication of Host Name.
