Routing in Wireless Sensor Networks |
This project, funded by
Enterprise Ireland, is part
of a wider project, involving two other research groups, for which Dr.
Collier is the PI. The routing element of the project is addressing the
design of energy-efficient routing protocols for WSNs.

Security in Wireless Sensor Networks |
This project is run in conjunction with
Dr. Mike Scott of
the School of Computing. We are
looking at the overhead associated with using elliptic curve cryptography on
WSN nodes, and the applications that are feasible, given this overhead.

Large-Scale Repackable Networks |
This project is funded by
Science Foundation Ireland under its Research Frontiers Programme. It is
looking at how a large-scale switching network may be built efficiently
using a multi-stage architecture. The wrinkle in this project is that the
switch is analog(ue), precluding the use of the classical Benes
network architecture (which breaks all the connections during
rearrangements).

Optical Burst Switching |
We've developed a novel reservation mechanism for OBS,
and are comparing its effectiveness to existing approaches in the
literature.

Routing in IP networks |
We've developed a new technique for load balancing in IP
networks using multiple routing tables. Such tables are available, for
example, in the Linux IP stack. Each table is populated using shortest-path
algorithms, but using a different view of the network. Our approach
inter-operates with MPLS, but requires no label management, and so lends
itself to supporting best-effort traffic in an MPLS cloud,

Properties of Multistage Networks |
| Dr. Collier's ongoing personal research addresses the
topological and routing properties of multistage networks.
