I am looking for new graduate students (see the announcement)
Future military missions will extensively use networked
devices along with wireless mobile ad hoc
and sensor networks, e.g., troops exchanging
strategic information, (un)manned vehicles/devices exchanging command-control messages,
critical audio/video streaming between soldiers etc. Clearly, such military applications are in
nature mission-critical and require
various levels of quality-of-service (QoS) and
security supports along with robustness and scalability. Providing such
supports is essential to the success of future military missions.
Realizing the importance of providing such supports, the
research community has been investigating various QoS
and security issues while calling for simpler but yet the-state-of-the-art mechanisms
for providing the desired levels of QoS and security.
Moreover, most studies are done within idealized simulation environments; thus,
it is not clear what will really work in practice. With these in mind, we are
mainly targeting the general area of providing QoS
support in wireless networks and planning to make our research as experimental
as possible
by implementing and testing our
ideas or other promising ideas using the wireless laptops and sensors that will be purchased through this grant. Experimentations will deepen our
understanding of the theoretical and practical limitations of wireless networks
and allow us to develop practical QoS mechanisms.
Taking the concerns due to dynamics of wireless networks into account, we
propose a reservationless, prioritization-based QoS support scheme and plan to develop necessary mechanisms
across the network and data link (MAC) layers.
Specifically, we plan to explore our recently proposed
distributed prioritization scheduling mechanism at the MAC layer along with new mechanisms
at the network layer such as determining
and maintaining QoS-based paths without requiring
global state-information. In addition, we plan to extend our proposed
mechanisms to
multi-radio, multi-channel wireless
networks to further increase the capacity.
While providing the envisioned reservationless,
prioritization-based QoS support, it is important to
consider unauthorized nodes that may not respect the underlying QoS mechanisms and degrade the QoS
capabilities through various attacks (e.g., DoS,
unauthorized access to the network, delete messages, inject false packets, or
impersonate a node). Accordingly,
our second important task in this project is to develop necessary security
mechanisms and integrate them into our QoS mechanisms
so that various attacks/intrusions can be detected and avoided while
maintaining the QoS-based operation of the network.
In addition to research, this project targets to
quantitatively and qualitatively improve the participation of minority students
in computer science while enriching the process of learning and discovery for
all students. Although our university is a Hispanic-dominated minority-serving
institution, the participation of these students in graduate level education is
very low. I believe the experimentation component of our research and the
fellowships that will be offered through this grant will attract many of these students
and allow us to involve all interested students in our
research through various educational activities such as independent studies, weekly seminars, outreach efforts, and mentoring.
