Abstract
Problem statement: Wireless technology has far growing with an increa sing demand of the Wireless networking technologies recent years. The wireless access network and cellular networks are being used to support their need. It is usually con nected to a wired backbone network. TCP is used to handle the congestion in wired network. However, it is not well suited for hybrid network consisting o f wired and wireless networks. Packet loss occurs in wireless network mostly due to high bit error rate, varying in transmission length, or link failure. Th ese scenarios are always misinterpreted by conventional TCP as a congestion loss. Hence, TCP sender performs congestion control which is unnecessary and leads to a poor network performance. Approach: A new algorithm proposed in this study is to differentiate the types of packet loss accurately. The algorithm will classify the packet loss and invoke proper correction mechanisms. Results: Our simulation results show the improvement of TCP performance as compared to the existing Selecti ve-TCP and TCP NewReno. Conclusion: The proposed algorithm on classifying packet loss shows the improvement of TCP performance.

Summary
To the dynamic network topology and host mobility (Leung and Li, 2006)-( Mondal and Luqman, 2007). The same effect is on a new packet loss differential algorithm to improve experienced as long as it requires retransmission TCP performance over hybrid wired/wireless networks. We propose an end-to-end solution to improve TCP performance over wired/wireless networks This is based on detecting the type of losses at the TCP receiver. The slow start threshold and The sender performs bulk data transfer (assume all congestion window size are not reset unnecessarily, packets are same size) and the routers or base station at resulting in better bandwidth utilization Congestion info stores the bandwidth measured at Fig. 6: Wireless loss differentiation over inter arrival the receiver when a packet loss is detected.
