An enhanced tree based key management scheme for secure communication of wireless sensory network
(BRAC University, 2010-04)
Wireless sensor networks (WSN) are mobile ad hoc networks in which sensors have limited resources and communication capabilities. Secure communications in some wireless sensor networks are critical. Key management is the ...
Efficiency of IPS and its effect on Bangladesh Power systems
(BRAC University, 2010-08)
Shortage of energy has always been a part of our life for many years in Bangladesh. Every year, the situation becomes more and more dire. In order to adjust with this, a some of us procured Instant Power Supply (IPS) to ...
Performance analysis of a multi-carrier CDMA wireless communication system with channel impairment
(BRAC University, 2010-04)
Analysis of the Bit Error Rate (BER) will be carried out for a Multi Carrier CDMA wireless communication link considering the effect of channels limitations like fading, delay spread etc. Different schemes of MC-CDMA will ...
Mobile robotic ARM manipulation
(BRAC University, 2010-04)
In this modern era, robotics has brought a revolutionary success in technology. In our thesis, we are going to implement a mobile robotic arm manipulator. The arm manipulator will perform embedded actions using microcontroller. ...
Design and development of a QPSK modulator
(BRAC University, 2010-04)
QPSK or Quadrature Phase-Shift Keying is a higher order modulation scheme used in digital modulation. In this project, we will be implementing a QPSK modulator for a wireless communication link. The carriers will be chosen ...
A multitasking PC based robotic ARM manipulator control system in RT-Linux environment
(BRAC University, 2010-04)
Automation in industries helps in achieving the target of quality standardization and process visibility. In overseas the industries are automated using different robots which work efficiently. But in a developing country ...
Design of an often cost affective wind power system for a remote Bangladesh locality
(BRAC University, 2010-12)
Demand for Energy is increasing day by day because of population increase and industrialization but we have very limited resources. In this critical stage of energy crisis, renewable energy is one of the most important ...
Performance analysis of a DWDM optical transport network with crosstalk
(BRAC University, 2010-04)
