The Transmission Control Protocol (TCP) was designed to provide reliable transport services in wired networks. In such networks, packet losses mainly occur due to congestion. Hence, TCP was designed to apply congestion avoidance techniques to cope with packet losses. Nowadays, TCP is also utilized in wireless networks where, besides congestion, numerous other reasons for packet losses exist. This...
Among transport layer protocols Nandita et al, in their work has shown that rate control protocol (RCP) is superior in its performance as compared to Transmission Control Protocol (TCP) and explicit control protocol (XCP), and emulates processor sharing in a much better way. A lot of work has been done for the improvement of RCP but the performance improvement for lossy networks is still an open issue...
In this paper, we present a implicit encoding technique that makes use of lower-layer packet reordering to superimpose covert messages onto a reliable data stream. In particular, since the TCP layer provides a reliable in-order data stream over the unreliable network layerpsilas IP datagram service, we can encode covert messages by artificially permuting IP packets before they leave the source and...
