Abstract:

Communications techniques and performance models are devised for communications networks in which mobile platforms, volatile traffic patterns, and interference are significant features. The main focus is on network organization and control configurations that support communications among semi- autonomous mobile platforms. Example platforms can support data gathering sensors and communications equipment aboard guided or maneuverable space vehicles satellites, aircraft, ships or grounded vehicles or persons. Network configurations with limited andor shared communications resources are considered. Analytical models are devised to characterize major performance issues. Matters of concern include maintaining network connectivity with mobile platforms that have active communications links, methods for allocating communications resources to gateways, dynamic assignment of resources and access rights. Topics investigated have included acquisition of spread spectrum signals, low-delay channel access protocols, call hand-off schemes, telecommunications traffic performance of mobile networks, computation vs. communication considerations, high speed packet switching, and aspects of self- organizing communications networks.
