3 doc.: IEEE Submission ETRI May 2013 Definition of the Peer Aware Communication peer-to-peer wireless personal area network –each device in the network can act as a client or server for the other devices in the network –allowing shared access to various resources such as configuration or control information, location information, sensing data, advertisement, multi-media contents, social contents, … –P2P WPAN provides the distributed physical network on top of which resource sharing applications is built scope of MAC for the P2P WPAN –infrastructure-less coordination –peer aware link establishment –group communication on the peer-to-peer links Slide 3

4 doc.: IEEE Submission ETRI May 2013 PAC enabled Networks (I) networks with the PAC enabled devices –networks of the PAC enabled devices only PAC WPAN –networks of the devices equipped with the PAC PAC enabled X-network (e.g. LTE, Ethernet, WiFi, … ) –hybrid networks of the PAC WPAN and the PAC enabled X- networks hybrid PAC network Slide 4 PAC WPANPAC enabled X-networkHybrid PAC Network PAC enabled device X-network device

5 doc.: IEEE Submission ETRI May 2013 PAC enabled Networks (II) PAC WPAN –fixed PAC WPAN –mobile PAC WPAN –fixed & mobile PAC WPAN PAC enabled X-network –as secondary network for the fixed X-network –as secondary network for the mobile X-network Hybrid PAC network –fixed PAC WPAN + mobile PAC enabled X-network –fixed PAC enabled X-network + mobile PAC WPAN Slide 5

6 doc.: IEEE Submission ETRI May 2013 PAC enabled Networks (III) possible network configurations with the PAC enabled networks –one PAC WPAN –multiple PAC WPAN –one PAC WPAN & one X-network –one PAC WPAN & multiple X-network –multiple PAC WPAN & one X-network –multiple PAC WPAN & multiple X-network Slide 6 PAC WPAN 1 PAC WPAN 2 PAC WPAN 1 X-network 1 PAC WPAN 1 X-network 2 PAC WPAN 2 PAC WPAN 1 X-network 1

7 doc.: IEEE Submission ETRI May 2013 Intra-less Coordination (I) Infra-less ? –free of the PAN coordinator –not singular PAN configuration –closed network, not connected to the world –not persistent network, disposable network Questions on the architecture of the PAC WPAN –who configures the network ? –who commences the network formation ? –who authenticates the PAC devices requesting to join the network ? –how identifies the PAC devices as peers ? what means peer-aware ? Slide 7

8 doc.: IEEE Submission ETRI May 2013 Intra-less Coordination (II) Possible usage scenarios of the PAC WPAN –peer network for all the devices in a space to produce periodic information –multiple peer networks which a device serves concurrently –peer network for a certain device formed by inviting the peer devices Slide 8 thing 6 wireless device6 thing 1 wireless device1 thing 5 wireless device5 thing 4 wireless device4 thing 2 wireless device2 thing 3 wireless device3 P2P network 1 P2P network 3 P2P network 2 space A thing 6 wireless device6 thing 1 wireless device1 thing 5 wireless device5 thing 4 wireless device4 thing 2 wireless device2 thing 3 wireless device3 P2P network 1 P2P network 3 P2P network 2 space A wireless device7 P2P network 4

9 doc.: IEEE Submission ETRI May 2013 Intra-less Coordination (III) Different from the already known WPAN –any device can be a client of the peer network, the client needs to be the host of the peer network –multiple peer networks might be collocated, a device can be a peer of multiple peer networks concurrently –peers are identified by the mission of the peer network, peer aware devices do their assigned job to carry out the mission –according to the mission of the peer network, infra-less peer network may be persistent network or disposable network –peer aware network may not need a connection to the world mostly Slide 9

10 doc.: IEEE Submission ETRI May 2013 Peer Aware Networks in the PAR PAC features –discovery signaling rate 100Kbps number of devices in the network get peer information without association relative positioning –coordination fully distributed, infrastructure-less membership in multiple groups, up to 10 multi-hop relay –transmission below 11GHz bands scalable data transmission rates, up to 10Mbps Slide 10

11 doc.: IEEE Submission ETRI May 2013 P2P WPAN Features (I) PHY supports for –transmitter below 11GHz scalable 100Kbps ~ 10Mbps relative positioning MAC supports for –access control fully distributed coordination multiple group coordination peering, information exchange without association multi-rate link connection –link layer networking localization location based networking multi-hop relaying Slide 11

12 doc.: IEEE Submission ETRI May 2013 P2P WPAN Features (II) Infra-less coordination –define the mission –set the specification of peer device and P2P network –search peers –start the formation of network –host peers –maintain P2P session –release the peers specification of the PAC coordination –peer profile peer group mission, member of peers capabilities of peer session P2P network identifier –peer-to-peer connection peer-to-peer link peer group casting –peer connections to multiple PAC WPAN multiple links from a peer n-m group casting Slide 12 PAC WPAN 1 HPD PD peer group casting PAC WPAN 1 HPD PD PAC WPAN 2 HPD PD n-m group casting

15 doc.: IEEE Submission ETRI May 2013 PAC WPAN Architecture (II) communication resources of the PAC WPAN –links between each components of the PAC WPAN –controlled objects of the PAC WPAN MAC RF channels and time allocated for the links unit timeslot measured by transmission time for some number of MAC frames PAC WPAN MAC –how long time to be allocated for the each type of links –how to resolve the contention –how to support a single P2P network, peer group casting –how to support multiple P2P network, n-m group casting –how to extend the P2P network, relaying Slide 15 host-proxy host linkpeer group linkhost-guest linkrelay linkpause unit timeslot host proxy host proxy host host host guest proxy host guest guest peer P2P groupguest peer host/proxy host host/proxy host guest peer guest peer host/proxy host host/proxy host guest peer number of MAC frame

16 doc.: IEEE Submission ETRI May 2013 PAC WPAN MAC (I) PAC WPAN MAC must support the various experience of service quality of higher layer TG8 might not need to be aligned with the 15.4 the MAC resources have to be customized to the mission of the P2P WPAN –configurable resource allocation along the life cycle of P2P network hosting phase, P2P phase, handshaking phase –configurable resource allocation for the each phase host, group, guest, relay, pause Slide 16

17 doc.: IEEE Submission ETRI May 2013 PAC WPAN MAC (II) configurable steps for supporting the life cycle of the P2P network –host broadcasts peer connection request with the peer profile –peers who listen the host broadcast peer connection request –host forms a peer network based on the localization of peers –maintain peer session or prolong the P2P session phase –meet the host, send data Slide 17 hosting phase P2P phase hosting phase (a) hosting phaseP2P phase EOPEOP (b) handshaking phase (c) handshaking phaseP2P phase (d) P2P phase EOPEOP
