Abstract
• We propose a universal approach that can simultaneously achieve both inter- and intra-piconet relaying.
• Our scheme can inter-relay packets across piconets without knowing the locations of the devices.
• Our scheme is backwardly compatible to IEEE 802.15.3 draft standard.

New Packets: Broadcast piconet info
• Sent by a PNC to the relaying DEVs to inform other PNCs about the DEVs under its converage
• Relay address : once a intermediate relaying node receive this packet, it overwrite its address onto this field.
• Max hop no. : the maximum number of hops allowable.
• Hop no. count : the number of hops the packet experienced.
• DEVn life time : the time that the relay node is anticipated to stay in his piconets
