This paper surveys various techniques for improving the performance of TCP in CDMA cellular networks. The two major issues that affect the performance of TCP in cellular networks are high packet loss rates due to physical layer impairments in the radio environment, and intermittent connectivity losses due to handoffs. TCP has been designed and tuned to perform well in traditional wired networks and is not well suited to handle either of the above two issues. Various techniques surveyed in this paper are classified into three categories depending upon the protocol layer (physical, link or transport) at which they are predominantly implemented.
