Error recovery:
Freeze-TCP -> avoids timeouts by sending a ZWA from receiver.
TCP probing :)
TCP Santa Cruz
TCP-Real
DAKS delayed acks
fast retransmission
TCP New Reno
TCP-SACK selective

No interest in proxy-based approaches:
Indirect-TCP
MTCP
Explicit Bad State Notification
WTCP
Snoop

Protocol Strategy
PROBING!
high goodput, energy-efficient

Read 'An End-to-End Transport Protocol for Extreme
Wireless Network Environments' (2006)

it extends TCP-sacks technique by incorporating:
ECN -> so the routers/base stations must be ECN enabled
uses FEC (Forward error correction) -> add redundant data into packet.
changing MSS (Maximum segment size) -> cwnd
