摘要：With the proliferation of mobile and wireless computing devices, the demand for continuous networkconnectivity exits for various wired-and-wireless integrated networks. Since Transmission Control Protocol(TCP) is the standard network protocol for communication on the Interne, any wireless network withInternet service need to be compatible with TCP. TCP is tuned to perform well in traditional wirednetworks, where packet losses occur mostly because of congestion. However cellular wireless networksuffers from significant losses due to high bit errors and mobile handoff. TCP responds to all losses byinvoking congestion control and avoidance algorithms, resulting in degraded end-to-end performance. Thispaper presents an improved Explicit Loss Notification algorithm to distinguish between packet loss due tocongestion and packet loss due to wireless errors and handoffs. Simulation results show that the proposedprotocol significantly improves the performance of TCP over cellular wireless network in terms ofthroughput and congestion window dynamics.
