METHOD FOR CONNECTING AN IP-BASED USN WITH AN EXISTING IP NETWORK, CAPABLE OF ASSIGNING INTRINSIC IP ADDRESSES TO EACH SENSOR IN A USN

摘要

PURPOSE: A method for connecting an IP-based USN(Ubiquitous Sensor Network) with an existing IP network is provided to enable sensor nodes in an IP-based USN system to have intrinsic IP addresses, thereby enabling a user to obtain desired information and service from any external network.;CONSTITUTION: Intrinsic IP addresses are respectively assigned to sensor nodes(S110). The sensor nodes broadcast their location information. An IP-USN router stores the broadcast location information in its own table. The IP-USN router broadcasts its own existence information to update the location information stored in the table.;COPYRIGHT KIPO 2010
