School 360
(Daffodil International University, 2019-12) Rahman, Sazzadur
This project titled “School360 - A Complete School, College, Madrasah, Coaching Center Management System” which can help the School, College, Madrasah, Coaching Center management to maintain their all activities. School360 is a large database system which can be used for managing your school's day to day business. School360 allows users to store almost all of their school's information electronically, including information on students, properties, teaching meteorites etc. Most importantly, this information can be easily shared with authorized users, records can be easily searched, and reports can be easily generated. School360 is software which is helpful for students as well as the school authorities. In the current system all the activities are done manually. It is very time consuming and costly.
Study Of Proxy Mobile IPv6
(Department of Computer Science and Engineering, Military Institute of Science and Technology, 2013-12) Sharmin Afroze, Lt; Sharmin, Nusrat; Rahman, Sazzadur
A network-based mobility management protocol called Proxy Mobile IPv6 (PMIPv6) is being actively standardized by the IETF NETLMM working group, and is starting to attract considerable attention among the telecommunication and Internet communities. Unlike the variousexistingprotocolsforIPmobilitymanagementsuchasMobileIPv6(MIPv6),which are host-based approaches, a network-based approach, PMIPv6 has salient features such as support for unmodiﬁed mobile nodes, support for both IPv4 and IPv6, efﬁcient use of wireless link and improved handover performance. In this thesis, we have explained the architecture of PMIPv6 with its detailed signaling diagram. We have compared PMIPv6 with MIPv6 in term of some characteristics and performance aspects and identiﬁed some drawbacks of PMIPv6. We have also presented handover latency calculation of MIPv6, HMIPv6 and PMIPv6 based on an analytical model. The results show that PMIPv6 has superior performance to other two protocols(MIPv6 and HMIPv6).
Study on Microwave Life Detection System
(Department of Computer Science and Engineering, Military Institute of Science and Technology, 2012-12) Wasim Azad, Md.; Prosad Roy, Bipul; Rahman, Sazzadur
Thousand of persons are being killed as a cause of earthquake. The disaster in the Dhaka City may claim thousands of lives due to Earthquake. It is said if survivors are found and rescued earlier the numbers of victims will be lower. There is no end to the number of lives lost as the result of such disasters as landslides, collapsed tunnels and avalanches. The microwave life detection system is developed for the search and rescue of victims trapped under the rubble of collapsed building during the earthquake or other disasters. TheproposedsystemutilizesL-bandfrequencywhichisabletodetectrespiratoryandheart ﬂuctuations. TheoperationprincipleisbasedonDopplerfrequencyshiftoftheelectromagnetic wave reﬂected from the buried victim. The schematic diagram of microwave Transmitting/Receiving (T/R) and clutter cancellation subsystem are included in this report. In this report various parts of a microwave life detection system such as antenna, directional coupler, and splitter has been discussed. By advent of this system the world death rate as a cause of an earthquake may decrease to greater extent.
