TCP in Wireless Networks<br />
● Theoretically the transport layer protocol should be independent of lower<br />
layers<br />
● But TCP is optimized for wired networks<br />
● TCP assumes that packet loss is due to congestion in the network<br />
● In wireless networks packet loss occurs due to the medium<br />
● Thus, performance of TCP in wireless networks is poor<br />
● Many approaches to solve the performance problem<br />
● Indirect TCP (as an example)<br />
● The end-to-end connection is broken in two parts<br />
