A Cross-Layer Based Improved TCP Protocol for Multi Hop Wireless Ad Hoc Networks
The congestion handling is the biggest single issue that makes the traditional Transmission Control Protocol (TCP) a poor choice for ad hoc wireless networks. In wireless ad hoc networks, if the packet loss occurs frequently for any reason, the size of TCP congestion window will stay at very low level most of the times, which naturally decreases the throughput of the network significantly. In this paper, the authors propose to develop a cross-layer based improved TCP protocol which ensures fair throughput and reliability. In this protocol, for any TCP connection, the data path is segmented and representative nodes are maintained in every segment.
