Abstract
A wireless hybrid network consisting at least one satellite and a plurality mobile ad hoc nodes . The nodes are assumed to be clustered into mobile groups within the footprint of the satellite , and the objective is to enable reliable communications between the various nodes . At least one relatively powerful gateway , also mobile, is deployed for each cluster of nodes to facilitate communication with a LEO or GEO satellite . The environment is characterized by the presence of terrestrial barriers or other severe channel impairments. One of the goals of the invention is to provide a mechanism by which a mobile gateway can change its position or define its trajectory based on the position and loading of the nodes in an ad hoc network, so as to optimize certain pre-defined performance criterion, such as power, overhead, throughput.
