PROJECT UNDER
PROGRESS
1. A Trustworthiness-based QoS Routing Protocol for Ad Hoc Networks
A comparison study on the
performance of an SRP (Secure routing Protocol), called Trustworthiness-based
QoS Routing (TQOS), to the commonly used ad hoc routing protocols, including
AODV and DSDV. Different scenarios are designed to test the attack-detection
capability of the SRP and the resulted performance. By using the OPNET
simulator, the SRP will be evaluated against the attacks of packet dropping,
selected forwarding, and Byzantine failures. After a thorough study has been
completed, critical changes in TQOS will be made to improve its performance in
both security and QoS.
2. Dynamic Channel Allocation Strategies in WLANs with Multiple APs
Recently, we have developed a few
new methods to dynamically allocate the radio channels in WLANs with multiple
APs. The goal is to improve channel efficiency and to minimize the co-channel
interferences at the same time. The existing software packages such GloMoSim
and NS-2 have limitations for us to quickly simulate our scenarios in order to
demonstrate our channel allocation methods. We have found that OPNET is an
excellent choice for our purpose of simulating channel allocations in WLANs.
The learning curve for the students is short due to the easy interface provided
by the software. The wireless modules provided by OPNET are very impressive by
its capabilities to handle all our simulation problems in this project.
COURSES USING
OPNET
The
graduate courses include EEL-5784:
Computer Network Design and Analysis and EEL-6xx: Computer Networks II.
The
first one focuses on the following topics - include theoretical basis for data communications,
transmission media; data link layer, medium access control sublayer, routing
algorithms and protocols, protocol modeling and performance analysis, typical
applications including the Internet, introduction to mobile and wireless
networks, network traffic, quality of service (QoS), security issues, and other
related areas. OPNET will be used to demonstrate the concepts and methods used
in the network design and analysis.
The
second one concentrates on the following - modeling and management of
interconnected networks, including an IP backbone network, WLANs, and wireless
ad hoc networks. Topics include: a) routing protocols: OSPF, BGP, MPLS,
on-demand routing; b) QoS: IntServ, DiffServ, QoS routing; c) security:
cryptography, PKI, IPsec, secure routing; d) management: fault management,
intrusion detection, traffic modeling and performance evaluations. OPNET will
be used to study the protocol performance, including MAC and routing protocols
with different enharncement.
Other
courses that also use OPENT include EEL-5591:
Wireless Communications and EEL-5xxx:
Advanced Topics in Computer Networks (offered once in a two-year plan).
