Split Connection Approach: Advantages
nBS-MH connection can be optimized independent of FH-BS connection
–Different
flow / error control on the two connections
nLocal recovery of errors
–Faster
recovery due to relatively shorter RTT on wireless link
nGood performance achievable using appropriate
BS-MH protocol
–Standard
TCP on BS-MH performs poorly when multiple packet losses occur per window (timeouts can occur on the BS-MH
connection, stalling during the timeout interval)
–Selective
acks improve performance for such cases
