We overview selected research developments obtained recently in our group that relate to cross layer networking across infrastructure and mobile ad hoc wireless networks. Topics are selected form the following developments:
a. Networking across mobile ad hoc wireless networks through the use of our Mobile Backbone Network (MBN) techniques. Algorithms and protocols have been developed and studied to dynamically synthesize a mobile backbone topology and to enable QoS routing across such an hierarchically constructed network.
b. Cross-layer operations across mobile wireless networks. Techniques for the combined selection and setting of modulation/coding schemes, transmit power levels, rate adaptations, MAC scheduling and routing procedures. We have been applying such studies to a wide range of networking systems, including WLAN, WMAN and cellular architectures. Energy aware operations have also been extensively studied, with applications to networks whose subscribers use energy limited devices, such as sensor networks. Fundamental performance bounds that involve code, rate and power adaptations have been attained.
c. Traffic and routing management of multi-segment networks in which gateway end nodes may employ multiple simultaneous routes to navigate traffic across different media. Utility oriented optimal traffic distribution across terrestrial and space based network segments.
