- Wireless 1394 over IEEE802.15.3 must allow a data reserved for delivery over a wired 1394 network to be delivered over an IEEE802.15.3 wireless network through bridging IEEE 1394 to IEEE802.15.3. Isochronous transfers on the 1394 bus guarantee timely delivery of data. Specifically, isochronous transfers are scheduled by the bus so that they occur in every 125 μs and require clock time synchronization to complete the real-time data transfer. IEEE1394.1 and Protocol Adaptation Layer for IEEE1394 over IEEE802.15.3 specify clock time synchronization for a wired 1394 bus network and wireless 1394 nodes, which are IEEE802.15.3 nodes handling 1394 applications, over IEEE802.15.3. Thus, legacy clock time synchronizations are best fit for a homogeneous network environment like IEEE 1394 or IEEE802.15.3 only. This paper proposes enhanced clock time synchronization method between IEEE 1394 and IEEE 802.15.3. In legacy synchronization between IEEE1394 and IEEE802.15.3, one of wireless 1394 bridge portals has to be wireless 1394 coordinator for IEEE802.15.3 network, but, in an enhanced method, one of wireless 1394 bridge portals doesn't have to be wireless 1394 coordinator. Any node within IEEE802.15.3 network side can be wireless 1394 coordinator. This may improve network flexibility effectively because the location of wireless 1394 coordinator dose not to be fixed. © 2006 IEEE.
