Abstract: |
From a patient safety perspective, time-consuming searches for life saving equipments
or drugs have been the subject of a hazard report. In addition to yielding significant
time saving Asset Tracking Systems (ATS) ensure all assets tracking. In this work,
an Ultra Wide Band (UWB) tracking system will be developed, that will automatically
captures the movement of in-house patients and clinical stuff. In addition to helping
staff locate equipment, our ATS will facilitate the use and distribution of inventory
by collecting and facilitating the analysis of data on equipment location over time
and hence prone to be tampered. |

|
Abstract: |
On-site building material and construction tools management offers a big challenge
to traditional asset tracking systems. In the same vein, when construction machinery
mobility is very frequent, data collection is often onerous for busy construction
crews. Construction managers determine the best way to track building material,
construction tools and equipment to rationally layout the most cost-effective plan
and schedule for completing the project. In contrast to conventional asset tracking
schemes such as Radio Frequency IDs (RFID), Infra Red IDs (IRID), Tagged IDs (TID)
to name a few, we will use Ultra Wide Band (UWB) technology in our project, that
is relatively new and gaining researchers interest in imaging as well as in tracking.

|
Abstract: |
Breast cancer is the most frequent malignancy among women in Pakistan. About half
(43.7%) of all breast cancers are locally advanced accounting to 40,000 deaths per
year. Due to the low contrast between cancer and normal tissue observed in X-ray
imagery, mammography has a high false negative rate (4% - 34%) and a high false
positive rate (70%). Thus, techniques that image other physical tissue properties
are vital to explore. This project aims at investigating microwave imaging for early-stage
Breast Cancer Detection (BCD). |

Abstract: |
Radio Frequency Identification (RFID) is the advance automatic techniques which
use RF waves for Identification of multiple objects at a time; hence along with
increase in range, object count per unit time also increases. We shall implement
a flexible system called Testbed with the help of rapid prototyping approach, which
utilizes high speed DSP kits, Reconfigurable IO boards i.e. FPGA boards, ADC boards
etc. Various Testbeds are developed by different universities and companies like
University of Vienna Austria (Flexible Dual frequency (LF and UHF) Testbed for RFID,
Testbed to assess new antenna design for tag by Georgia Institute of Technology
USA. In collaboration with these research labs, we shall implement a Dual Frequency
Testbed (UHF and Microwave) which will incorporate generic features for e.g., microwave
standards, ISO standards conformance tests, Interrogator transponder protocols etc. |

Abstract: |
Traditional networks use point-to-point channels for the cost effective communication,
but they perform poorly wherever dynamic topologies are appeared. To make a transmission
successful interference must be avoided or at least controlled. The channel then
becomes the shared resource whose allocation is critical for proper operation of
the network. Such access schemes are called multi-access protocols. We implemented
various Anti-collision protocols successfully in Matlab to investigate their performance.
These techniques are Pure ALOHA, Slotted ALOHA, non-persistent CSMA and slotted
np-ISMA. Some more advance protocols like tree based protocols and collision avoidance
protocols will also be implemented in Matlab. Currently the FPGA implementation
of these Matlab implemented protocols is in progress. |

FoTON: Fault Tolerant Optical Network in The Last Mile |

Abstract: |
Many new applications and services have emerged amidst the rapid growth of internet
and telecommunications industry demanding high speed connectivity till the first
/ last mile. So to cope with this rising demand more and more companies are deploying
optical fiber networks till the client’s premises. The main issue with optical networks
in the developing countries like Pakistan is the network failure due to fiber cuts.
In metropolitan area ring networks are deployed so that the traffic can be rerouted
in case of fiber cuts thus reducing the network restoration time but in the last
mile deploying a ring network might not be feasible in all cases, due to congested
urban environment and associated high costs of optical fiber deployment. So another
feasible alternative is to provide an optical wireless link to clients that require
high availability and reliable service at all times. In case of any link failure
due to fiber cuts, the network traffic would be rerouted instantaneously to the
optical wireless link. Our research is directed towards the design and placement
of these optical wireless links so that the network may recover instantaneously
from any failures and provide reliable high speed connectivity. |

Abstract: |
The growing customer demands for bandwidth intensive services are accelerating the
need to design an efficient “last mile” access network in a cost effective manner.
Thus, besides its enormous transport capacity, today’s access infrastructure should
bring operational efficiencies and the convenience of mobility to end users. In
this scenario, Urban Optical Wireless Communication (UOWC) Network is a prime choice
as an effective means of transferring data at high rates in the first / last mile.
In UOWC Network light beams propagating through the atmosphere carry the information
from the transmitter to the receiver. UOWC boasts many advantages over its rivals.
Notably, UOWC facilitates rapidly deployable, lightweight, high-capacity communication
without licensing fees and tariffs. However, UOWC still faces many challenges, including
how to improve communication performance in adverse weather conditions (like fog)
or during wind sway. Our research is focused on presenting and evaluating novel
approaches on network level to deal with these issues and enable UOWC Network to
bridge the last mile gap. |

Wavelength Division Multiplexing – Passive Optical Network |

Abstract: |
To support the introduction of new high-speed services and the consequent growing
bandwidth demand, operators are moving to the adoption of a fiber-based access network.
Multimedia and video services to residential users (broadcast, on-demand, or interactive
high-quality video services), applications such as users-provided contents and other
interactive applications – such as entertainment/gaming, educational services and
so on – need a bandwidth (in terms of both peak and guaranteed bandwidth) and a
quality of service that can only be guaranteed by an optical access network. The
passive optical network (PON) is an optical fiber based network architecture, which
can provide much higher bandwidth in the access network compared to traditional
copper-based networks. Incorporating wavelength-division multiplexing (WDM) in a
PON allows one to support much higher bandwidth compared to the standard PON, which
operates in the “single – wavelength mode” where one wavelength is used for upstream
transmission and a separate one is used for downstream transmission. The WDM – PON
is a revolutionary and scalable broadband access technology that will provide much
higher bandwidth to end users. There is a broad consensus on WDM – PON as the target
structure to provide an ultra-fast and reliable access to Internet and other shared
network resources, but the huge investments needed has until now slowed down its
introduction, limiting massive deployments of WDM – PON and pushing for the research
and development of a cost efficient WDM – PON Network architecture and protocol. |

Abstract: |
Modern automobiles have typically hundreds of sensors for different tasks, such
as safety, navigation and engine condition monitoring. However to collect data using
typical wired sensor networks has always been expensive, as the installation and
maintenance costs are very high. A typical advance automobile has many kilometers
of cables to connect the sensors. WSN (Wireless Sensors Network) is a term used
to describe an emerging class of embedded communication products that provide redundant,
fault-tolerant wireless connections between sensors, actuators and controllers.
Compared to wired networks WSNs can provide better Ability to withstand harsh environmental
conditions, node failures, mobility of nodes and can have a large scale of deployment.
In an automobile a WSN must be able to provide several types of technical information
to the user, the technical data can include fuel consumption, identification of
wrong tire pressure, acknowledgment of illumination failures (turn lights, brake
lights and front lights etc). For the transmission and processing of the signals
MICAz ZigBee (MPR2400) operating at 2.4GHz will be used along with the TinyOs. TinyOs
is an open source operative system developed for WSNs. It is of small size and is
already been used by crossbow to trace automobile parts for the industry purpose.
The MIB510 interface board will be connected to a computer by using the serial port,
and the MICAz MTS310 sensor node will be used to connect the sensors that are not
on the board via the Digi-Key H2163-ND connector. The tire pressure sensor, light
sensor, temperature sensor and the acceleration sensors will be used, and all the
data will be finally monitored by the computer. |
