Mobile applications must operate in environments which experience rapid and significant fluctuations in the quality of service (QoS) offered by their underlying communications infrastructure. These fluctuations may be the result of explicit changes between networks, increased competition for network resources or degradation of service due to environmental factors. In order to continue to operat...

Photonic networking technologies have the potential to revolutionise future military aircraft data communications, delivering substantial improvements in networking performance, reliability, cost and security. More particularly, wavelength division multiplexing (WDM) can provide a huge bandwidth-to-weight ratio as well as enhanced routing flexibility, connectivity and network survivability. In ...

Effective response to natural or man-made disasters (i.e., terrorism) is predicated on the ability to communicate among the many organizations involved. Disaster response exercises enable disaster planners and responders to test procedures and technologies and incorporate the lessons learned from past disasters or exercises. On May 31 and June 1, 2002, one such exercise event took place at the ...

The next generation of military communications satellites may be designed as a fast packet-switched constellation of spacecraft able to withstand substantial bandwidth capacity fluctuation in the face of dynamic resource utilization and rapid environmental changes including jamming of communication frequencies and unstable weather phenomena. We are in the process of designing an integrated sche...
