TCP Vs. UDP Performance Evaluation For CBR Traffic On Wireless Multihop Networks
White Papers More precisely, TCP and UDP are studied as different transport layer alternatives and their performance is evaluated with respect to QoS (i.e.mean/instant throughput as well as max and mean delay) and power behavior under multimedia-like streaming...

Interaction Between TCP And UDP Flows In Wireless Multi-Hop Ad Hoc Networks
White Papers The interaction between TCP and UDP flows are examined experimentally in simple scenarios, involving between three and four nodes. Early results show that TCP's congestion control is not tuned to wireless multi-hop settings, resulting in...

NUTSS: A SIP-Based Approach To UDP And TCP Network Connectivity
White Papers So far, this work has been limited to UDP because of the assumed impossibility of establishing TCP connections through NAT, and because of the difficulty of predicting port assignments on certain common types of NATs.
