Which among the following does not cause performance degradation on TC

1.	Which among the following does not cause performance degradation on TCP level?(a) Link error(b) Packet loss(c) Admission control(d) Access delayI have been asked this question in a national level competition.My question is based upon Next Generation Wireless Network in chapter Next Generation Wireless Network of Cognitive Radio
Answer» Right option is (d) Access delay The best I can EXPLAIN: Transmission Control Protocol is a connection oriented, reliable, END to end protocol of the transport layer. TCP generally exhibits performance degradation in wireless networks due to a high packet loss rate. COGNITIVE radio introduces NEW challenges such as interruption due to loss of availability of a channel.
