<p>A wireless hybrid network consisting at least one satellite 118 and a plurality mobile ad hoc nodes 104. The nodes 104 are assumed to be clustered into mobile groups 102 within the footprint of the satellite 118, and the objective is to enable reliable communications between the various nodes 104. At least one relatively powerful gateway 110, also mobile, is deployed for each cluster 102 of nodes to facilitate communication with a LEO or GEO satellite 118. The environment is characterized by the presence of terrestrial barriers 100 or other severe channel impairments. One of the goals of the invention is to provide a mechanism by which a mobile gateway 112 can change its position or define its trajectory based on the position and loading of the nodes 104 in an ad hoc network, so as to optimize certain pre-defined performance criterion, such as power, overhead, throughput.</p> |
