1. Introduction 1. Introduction
NFC is a set of short-range wireless technologies, typically NFC is a set of short-range wireless technologies, typically
requiring a distance of 10 cm or less. NFC operates at 13.56 MHz on requiring a distance of 10 cm or less. NFC operates at 13.56 MHz on
ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to
424 kbit/s. NFC always involves an initiator and a target; the 424 kbit/s. NFC always involves an initiator and a target; the
initiator actively generates an RF field that can power a passive initiator actively generates an RF field that can power a passive
target. This enables NFC targets to take very simple form factors target. This enables NFC targets to take very simple form factors

4.5. Neighbor Discovery 4.5. Neighbor Discovery
Neighbor Discovery Optimization for 6LoWPANs ([RFC6775]) describes Neighbor Discovery Optimization for 6LoWPANs ([RFC6775]) describes
the neighbor discovery approach in several 6LoWPAN topologies, such the neighbor discovery approach in several 6LoWPAN topologies, such
as mesh topology. NFC does not support a complicated mesh topology as mesh topology. NFC does not support a complicated mesh topology
but only a simple multi-hop network topology or directly connected but only a simple multi-hop network topology or directly connected
peer-to-peer network. Therefore, the following aspects of RFC 6775 peer-to-peer network. Therefore, the following aspects of RFC 6775
are applicable to NFC: are applicable to NFC:
o In a case that an NFC-enabled device (6LN) is directly connected o When an NFC-enabled device (6LN) is directly connected to a 6LBR,
to a 6LBR, an NFC 6LN MUST register its address with the 6LBR by an NFC 6LN MUST register its address with the 6LBR by sending a
sending a Neighbor Solicitation (NS) message with the Address Neighbor Solicitation (NS) message with the Address Registration
Registration Option (ARO) and process the Neighbor Advertisement Option (ARO) and process the Neighbor Advertisement (NA)
(NA) accordingly. In addition, if DHCPv6 is used to assign an accordingly. In addition, if DHCPv6 is used to assign an address,
address, Duplicate Address Detection (DAD) MAY not be required. Duplicate Address Detection (DAD) MAY not be required.
o In a case that two or more NFC 6LNs meet within a sigle hop range o When two or more NFC 6LNs meet, there MAY be two cases. One is
(e.g., isolated network), one of them can become a router for that they meet with multi-hop connections, and the other is that
6LR/6LBR. If they have the same properties, any of them can be a they meet within a sigle hop range (e.g., isolated network). In a
router. Unless they are the same (e.g., different MTU, level of case of multi-hops, all of 6LNs, which have two or more
remaining energy, connectivity, etc.), a performance-outstanding connections with different neighbors, MAY be a router for

have the same properties, any of them can be a router. Unless
they are the same (e.g., different MTU, level of remaining energy,
connectivity, etc.), a performance-outstanding device can become a
router. Also, they MAY deliver their own information (e.g., MTU
and energy level, etc.) to neighbors with NFC LLCP protocols
during connection initialization.
o For sending Router Solicitations and processing Router o For sending Router Solicitations and processing Router
Advertisements, the NFC 6LNs MUST follow Sections 5.3 and 5.4 of Advertisements, the NFC 6LNs MUST follow Sections 5.3 and 5.4 of
