ABSTRACT
Universities and Institutions these days’ deals with issues related to with assessment of large number ofstudents. Various evaluation methods have been adopted by examiners in different institutions to examiningthe ability of an individual, starting from manual means of using paper and pencil to electronic, from oralto written, practical to theoretical and many others.There is a need to expedite the process of examination in order to meet the increasing enrolment of studentsat the universities and institutes. Sip Based Mass Mobile Examination System (SiBMMES) expedites theexamination process by automating various activities in an examination such as exam paper setting,Scheduling and allocating examination time and evaluation (auto-grading for objective questions) etc.SiBMMES uses the IP Multimedia Subsystem (IMS) that is an IP communications framework providing anenvironment for the rapid development of innovative and reusable services Session Initial Protocol (SIP) isa signalling (request-response ) protocol for this architecture and it is used for establishing sessions in anIP network, making it an ideal candidate for supporting terminal mobility in the IMS to deliver the services,with the extended services available in IMS like open APIs, common network services, Quality of Services(QoS) like multiple sessions per call, Push to Talk etc often requiring multiple types of media (includingvoice, video, pictures, and text). SiBMMES is an effective solution for mass education evaluation usingmobile and web technology.In this paper, a novel hybrid component based development (CBD) model is proposed for SiBMMES. AComponent based Hybrid Model is selected to the fact that IMS takes the concept of layered architectureone step further by defining a horizontal architecture where service enablers and common functions can bereused for multiple applications. This novel model tackle a new domain for IT professionals, its ideal tostart developing services as a small increments using the component and then adding new functionalitiesand improvements over time. The proposed novel model will be highly customizable for any university whoacquired to adopt similar IMS based mass examination system. This model will be compatible with thetraditional question-answer style examination and could meet the requests of the mass examination, such asuniversity entrance exam, International Computer Driving License exam, etc.
