We identify the properties of typical WWANs based on studies on the CDPD (Cellular Digital Packet Data) network, simulate (ns-2) the environment and design our protocol (WTCP) in this simulation environment to compare it with TCP-NewReno, TCP-Vegas, and Snoop-TCP. We also evaluated an implementation of the protocol in the CDPD network and found substantial performance improvements over an off-the-shelf TCP. For ad hoc networks, we propose and evaluate (using ns-2 simulator) a congestion control mechanism which uses hop-by-hop rate control with back-pressure. We show that our protocol has improved fairness properties compared to TCP based protocols. Made available in DSpace on 2015-09-25T20:19:16Z (GMT).
