“…It maintains its own timers for retransmission of buffered packets, implements selective transmission etc. by this way snoop hides loss of packets from FH, by not propagating duplicate acknowledgments, and thereby it prevents further invocations of congestion control mechanism [5].…”

Abstract-Computer networks have experienced an explosive growth over the past few years, which has lead to some severe congestion problems. Reliable protocols like TCP works well in wired networks where loss occurs mostly because of congestion. However, in wireless networks, loss occurs because of bit rates and handoffs too. TCP responds all losses by congestion control and avoidance algorithms, which results in degradation of TCP's End-To-End performance in wireless networks. This paper discusses different issues and problems regarding use of TCP in wireless networks and provides comprehensive survey of various schemes to improve performance of TCP in Wireless Networks.Index Terms-TCP, mobile-IP, wireless networks, protocol design.

“…An extension proposed to random delay detection (RED) is Explicit Congestion Notification (ECN) [5]. RED is an active queue management mechanism in routers, it detects congestion before the queue overflows and provides an indication of this congestion to the end nodes.…”

“…The snoop protocol developed by Berkeley is an example of a TCP-Aware link-layer protocol [10].It is a hybrid solution which uses concepts from the link-layer schemes and the split connection approaches. Unlike the other solutions discussed, the basic snoop protocol is specifically designed for data transfers from the fixed host to the mobile host.…”

“…The Snoop Protocol [3] was designed to solve the burst/intermittent packet loss due to high bit error rates and short temporary disconnections experienced by TCP in wireless link. The Snoop agent is designed to reside on the router between the wired and wireless link, referred to as the gateway, or base station (BS).The role of the snoop agent is to monitor the TCP packets transmitted from a fixed host to a mobile host and vice versa.…”

Providing Internet services over wireless links has grown rapidly in recent years. TCP (Transmission Control Protocol) has been performing well over the traditional wired networks where packet losses occur mostly because of congestion, it cannot react efficiently in wireless networks, which suffer from significant non-congestion-related losses due to reasons such as bit errors and handoffs. The paper shows how Explicit Congestion Notification (ECN), Snoop protocol and their combination can be used to improve the performance of TCP in Wi-Max network, ECN will help in congestion control and SNOOP will retransmit the packets that are lost from nodes in between, saving nearly half the retransmission time and avoiding the decreasing in transmission speed. This paper investigates the performance of above mentioned protocols over Wi-Max wireless scenario which improves the various parameters of TCP such as throughput. The results of the same can be demonstrated on NS2 simulator (WiMax module ns-nist-wimax.tgz).
