Efficiency through Eavesdropping: Link-layer Packet Caching
... RTS-id adds 32 bits of overhead to the small RTS packets. On links in which RTS-id does not provide benefit, this cost may loom large, because 802.11 transmits RTS/CTS packets at the lowest possible rate, 1 Mbps, while the data may be sent at higher rates. Moreover, for networks that would not otherw ...
