4.After the RPR ( Resilient Packet Ring ) protocol draft has been proposed, RPR promptly becomes a hotspot of research. But the special RPR chips are not commercialized.
6.AIr is the base protocol of infrared wireless LANs. AIr adopts No Packet Level Acknowledgement Protocol(NoPLACK),Packet Level Acknowledgement Protocol,SW-ARQ in AIrMAC,AIr Link Control,and AIr Link Manage.
8.By sending Address Resolution Protocol(ARP)packet using the Network Driver Interface Standard(NDIS)protocol driver to the destination computer and parsing the ARP packet with the NDIS protocol driver can detect the link status quickly. The ARP packet and the structure of NDIS are introduced.
10.A novel automatic repeat request protocol called cooperative ARQ protocol was studied, which exploited cooperative diversity. A relay terminal was requested to retransmit an erroneously received packet in the proposed protocol.
