This work studies centrality metrics as forwarding load predictors, for both unicast and multicast traffic, within dynamic ad hoc network topologies. We present results from a series of emulation experiments based around an emergency response mobile network scenario. From collected temporal topological and traffic data, we calculate a rank correlation measure between predictive centrality metrics...
This paper describes a new implementation of the Elastic Multicast (EM) protocol including new design enhancements for improved dynamic operation. The paper also presents additional performance data collected from emulation-based mobile network experiments. EM is a low complexity extension to Simplified Multicast Forwarding (SMF) that adds group-specific dynamic pruning of the SMF-based multicast...
This work presents new experimental results examining the loss tolerant unicast congestion control behavior of the NACK-Oriented Reliable Multicast (NORM) transport protocol documented initially as Internet Proposed Standard, Request for Comments (RFC) 5740. While RFC 5740 specifies a reliable multicast UDP-based transport protocol, NORM also has the ability to provide loss tolerant UDP unicast reliable...
