Our work explores the impact of aggressive/conservative congestion control strategies on the fairness and efficiency of reliable transport protocols, in a wired/wireless environment. Based on experiments, we study the behavior of congestion control mechanisms in response to wireless errors, and transient congestion caused by a small number of competing(More)
Mobile networking devices autonomy can be prolonged by condensing sporadic traffic at the last hop, allowing the receiver to sleep during idle intervals. We claim that Delay Tolerant Networking principles are a natural fit for this application and, along with a novel rendezvous mechanism, employ DTN to achieve energy efficiency. The effectiveness of the(More)
