Heterogeneous networks for public safety applications
Summary
I have been conducting research on wireless ad hoc and sensor networks for public safety applications in the following two aspects and graduated five Ph.D. students and supervised one postdoc.
(i) Technologies supporting network substrate: Since broadcasting is a major way of communications in public safety applications, we have investigated its related medium access control problem. Considering harsh working and communication environments where public safety applications may run, we have also studied failure-resilient unicast and disruption-tolerant multicast routing schemes. As network management is important for distributed collaborations in heterogeneous networks supporting public safety applications, we have also studied applications of ontology in hierarchical, multi-tier networks for network management in wireless ad hoc and sensor networks.
(ii) Middleware enabling application adaptations: As the performance of public safety applications running across wireless ad hoc and sensor networks is challenged by the physical limitations and the dynamic availability of resources in mobile devices and wireless networks, we have investigated adaptive and reflective middleware that enables application adaptations.
