Split Connection Approach: Advantages
n BS-MH connection can be optimized independent of FH-
BS connection
Different flow / error control on the two connections
n Local recovery of errors
Faster recovery due to relatively shorter RTT on wireless link
n Good 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
