In Wireless networks nodes send information from one point to another by using electromagnetic waves without relying on any physical connection. The main benefit of mobile wireless networks is access to the application from anywhere and at anytime. The wireless network is preferred because the cost of wired network is expensive due to the high cost of Ethernet cables, hubs and switches. Wireless networks based on IEEE 802.11 allow seamless access to organization network. The most widely used wireless standard is IEEE 802.11b which is a moderate-range, moderate-speed technology. It extends throughput up to 11Mbps using the same 2.4GHz as IEEE 802.11. TCP is a transport protocol used by the applications which require guaranteed delivery and best suited for applications which require high reliability and whose transmission time is relatively less critical. TCP guarantees that the data transferred arrives in the same order in which it was sent. TCP connection involves negotiating the parameters and establishing the connection. Once the connection is created then the data transfer will begin. After transmission of data the connection will be terminated. TCP [1] transfers a continuous stream of octets between its users in each direction by grouping some number of octets into segments through the internet system. TCP must recover data from damage, loss, and duplicate by the internet communication system. This is achieved by assigning a sequence number to each octet transmitted and
