Abstract: Autoband's distributed networking intelligence provides a novel architecture capable of dynamically reconfiguring communications pathways consisting of links whose transmission media are opportunistically and dynamically selectable. At least one constituent node in such automatically configurable transient pathways is mobile, for example, information (source) server, intervening router node(s), gateway server and/or client device. Additionally, Autoband's ad hoc communications pathways may seamlessly and dynamically integrate (i.e., “graft”) into standard fixed node networks such as terrestrial networks, other wireless networks or combinations thereof. These communications may consist of point-to-point or multicast links. An economic market-based approach further assures allocation of available network resources (i.e., bandwidth and processing) needed to achieve the most optimally resource efficient communications pathway configurations for the totality of communications.
