Abstract

Transmission Control Protocol (TCP) is working well in wired networks. TCP needs modification to work well in wireless networks. This work analyses the performance of the proposed two TCP cross layer flavours, namely the TCP-AL and TCP-WPAL. The cross layer interaction (TCP-WPAL) produces better performance than the TCP-AL. The PDR (Packet Delivery Ratio) of the TCP-WPAL is increased, and the delay and jitter of the TCP-WPAL are decreased in multihop wireless networks. Keywords: TCP, Wireless networks, TCP-AL and TCP-WPAL
