Abstract: Provided is a method and device for low power networking based on near field communication (NFC). The device for low power networking based on NFC may include an adaptation layer for the NFC configured to request a link layer node identification (ID), and a logical link layer including a binding to NFC for returning the link layer node ID to the adaptation layer for the NFC to secure an internet protocol (IP) connectivity in response to a request for the link layer node ID.

Abstract: Provided are a method of transmitting an Internet Packet version 6 (IPv6) packet over near field communication (NFC) and a device for performing the method. The method of transmitting an IPv6 packet over NFC includes receiving the IPv6 packet through a Logical Link Control Protocol (LLCP), and transmitting the IPv6 packet to an Information Field in Protocol Data Unit (I PDU) of the LLCP, and transmitting the IPv6 packet through an adaptation layer for IPv6 over NFC, wherein the maximum number of octets in the I PDU is determined based on a Maximum Transfer Unit (MTU).

Abstract: Provided is a method of defining an interface identifier (IID) of an Internet Protocol version 6 (IPv6) address and devices operating the same, wherein the method includes defining a first IID and a second IID in an IID based on a predetermined value at a predetermined location in the IID of an IPv6 address, assigning, based on an node identification (ID), a first node ID to the first IID and a second node ID to the second IID; and assigning information on a network connecting condition of a communication device to at least one of a first sub-IID corresponding to an area excluding the first node ID in the first IID and a second sub-IID corresponding to an area excluding the second node ID in the second IID.
