The purpose of the lab is to provide resources to undergraduate and graduate students to conduct research in the Telecommunications area. It also provides help to students who wish to complete their senior projects and MS projects in the Networking and Communication area. The lab has the following tools: OPNET Modeler, OPNET MPLS Model, OPNET Wireless module, ILOG CPLEX (solver), and ACC and ACC (a homegrown simulator for MPLS TE). The lab serves the following courses: Computer Networks, Network Protocols and Standards, Topics in Internet Research, Advanced Networks, Multimedia Communications, Optical Networks, Analog and Digital Communication, and Network Security.

Preemption in DiffServ awar MPLS Traffic Engineering Architecture
Investigator: Dr. Zartash Uzmi/Shahab Baqai
Project Duration: September 2005 - April 2006
Funded by LUMS ( Rs. 120000 )
Bandwidth allocation for different traffic types is a fundamental problem for network service providers. This problem is further intensified when the requested bandwidth exceeds the available unused bandwidth, thereby resulting in not all requests being complete served. In a DiffServ context, where tere are different traffic types. preemption of lower priority requests can lead to greater placement of higher priority requests. The choice of requests to be preempted is an open research problem and therefore has been the focus of many studies. Wth the integration of MPLS with Diffserv, new issues for preemption have arisen.

With the rapid growth of Internet, customers are demanding multimedia applications such as telephony and video on demand, to be avilable on the Internet. The greatest challenge facing providers of these services is the provisioning of Quality of Service (QoS). The best effor service provided by IP layer fails to provide the desired level of QoS guarantees. The key requirements of multimedia traffic are low packet loss and bounded jitter. These constraints require the network to provide badwidth and delay guarantees. The ability to differentiate and subsequently route traffic based on its required constraints is the key to providing a guaranteed service. Therefore, recent advances in Diff-Serv aware MPLS traffic engineering promises to provide a scalable architecture for the provisioning of QoS for real time applications.
Energy Efficiency in Wireless Sensor Networks
Investigator: Dr. Zartash Uzmi
Project Duration: January 2005 - January 2006
Funded by LUMS ( Rs. 180000 )
Advances in IC fabrication, RF design, and MEMS-based technology have made it possible to integrate DSP and sensing in a single chip with low development cost. These chips or sensor observe a physical phenomena and report data about that phenomena to the interested observer. A sensor generally consists of sensing hardware, memory, battery, embedded processor and transceiver.
Optimized Explicit Routing in a Mesh
Investigator: Dr. Zartash Uzmi
Project Duration: September 2004 - February 2005
Funded by LUMS ( Rs. 90000 )
The traffic engineering problem can be defined as an optimization problem as follows: Given a fixed topology and a fixed source-destination matrix of traffic to be carried, what routhing of flows offer the best overall performance? For a specific network the objective function must represent the goals of the network administration. But generally the question is, "how does one make the most effecitve use of the available bandwidth?"
Restoration Routing using Diff-Serv aware MPLS Traffic Engineering
Investigator: Dr. Zartash Uzmi
Project Duration: September 2004 - February 2005
Funded by LUMS ( Rs. 90000 )
In this project we propose a restoration routing framework which uses Diff-Serv aware MPLS traffic engineering [5]. Restoration routing implies setting up bandwidth guaranteed backup paths which are link and node disjoint from their corresponding primary paths. Provisioning restoration routing - in the presence of bandwidth guarantees - is essential.
