4 Common discovery mode for PAC WPAN Common MAC/PHY for PAC discoveryis different from the communication mode.should be simple and energy-efficient.provides fast and scalable PD discovery mechanism.NHLMACCommon ModeMACCommunication ModePHYCommon ModePHY 1PHY 2PHY 3
5 Illustration of PD discovery PD ADiscovery-RequestTCSPD BPD CAsynchronous Request command Tx:PDs do not need to be synchronized.But, TR > TCS
6 PD discovery via common mode Simple but fast discovery procedure:Asynchronous channel accessNot passive PD discovery (listening/scanning the channel)Active PD discovery using request commandLow power operation:Every PD shall sample the channel periodically.PD that wishes to discover neighboring devices sends request command longer than the channel sample listening period.Scalable discovery :Response only to the appropriate PD discovery requestAvoid collision due to responses from unnecessary PDsSave power consumption due to unnecessary Tx/RxDiscovery request includes IDs to discover.
