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

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 ?

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

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

Design Goals of IEEE 802.15.8
• Design considerations on PAC WPAN
– need to interpret the higher layer service in view of MAC and PHY
– support the interfaces to the X-network
– form a peer network for persistent use and for temporary use
– harmonize co-located multiple peer networks

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

P2P network• hosting phase, P2P phase, handshaking phase
– configurable resource allocation for the each phase• host, group, guest, relay, pause

– 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
