Mobile Computing

Lecturer of this course was my Professor (i should pay more attention 😀 ). He used Introduction to Wireless and Mobile System 2nd edition by Dharma P. Agrawal and Qing-An Zeng as text book. That book explains how wireless system works, how mobility is supported, how infrastructure underlies such a systems and what interaction is needed among different functional component. Some of the chapter are : Probability, Statistics and Traffic Theories, Cellular concept, Mobile communication system, Ad hoc and sensor networks, Wireless Mans, Lans and Pans etc. This text book tell us basic concept (not in detail) of mobile system works. When we need more detail explanation about each chapter we should find another references related.

This tentative mark for this course was divided into three main parts. Home works, Final exam and Final project. I have done well for the home works and final exam… now i’m waiting for the result of my final project. The final project was about reviewing some papers related to the course topic and wrote down our report.

Multimedia Wireless Networks

Hohohoho… this course was very difficult to me. Prof Ray used Multimedia Wireless Networks – Technologies, Standards and QoS from A Ganz and Z Ganz as the text books. But for this semester we just finished until chapter four from that book. The book tell us about Wireless networks including QoS (Quality of Services) mechanism based on related technology. Almost a semester we studied about Standards and QoS in IEEE 802.11 family, IEEE 802.16e (the main part). The text book only used as reference, basic material came from papers and another people research. So, actually i should take the another prerequisite course before take this course. Prof Ray also teach us about  recent technologies in wireless multimedia networks. One of the class material was come from conference. We should go to Taipei WiMax Showcase and Conference to learned about recent technology in WiMax.

This course gave use two major point for the result. Final exam and Final project. I’m not satisfied with my ability in both of that categories. I have bad performance in presentation for the final project and i loss my final exam (may be only half from the max value 😦 ). Hope i will pass this course. Amin.

Chinese Course

Finally… this was my course that excluding from my credits. This course just for having fun. Basic Chinese Listening and Speaking level 1 was the name of this course. I went to the class twice a week, on tuesday and thursday night. Almost the student from this class came from Indonesia. So, when the Wang Chen-chen laoshi (teacher, red) tell us in chinese… we (yinni ren) make some chit chat in Indonesian language 😀 . This course is very useful for me, i know how to spell a word in chinese and how to count for buying something 🙂 .

Wang Laoshi divided the course exam in three ways. Midterm exam, Final Exam and Oral presentation. Midterm and Final exam was writing exam and for the oral presentation we should tell some speech in Chinese. I get good result for this course (bashiqi) 😀 . Practical Audio-Visual Chinese was our text book for this course.

*bashiqi = eighty seven

Two days ago (Thursday, red) was my last day in this semester. At that day I had my last exam in computer networks course for this semester. For this semester I took five course (Computer Networks, Mobile Computing, Multimedia Wireless System and Thesis, Disertation Presentation and Tehcnical Writing), four is the principal course and the last one was Chinese course (exclude from my credits). But, in the middle of the semester I withdraw thesis, disertation presentation and technical writing.

Computer Networks

This course taught basic concepts of computer networks. Prof Chen used Computer Networks 4th edition from Tanenbaum – Prentice Hall as text book. Actually that book is familiar to me, because i have already get computer networks in under graduate school with the same text book. But, at that time… i knew nothing at all. Came to the class, feel as sleep… and so on 😀 . All the chapter in this book tell the story of computer networks in basic network protocol. The chapter is arranged by the OSI reference model from lowest layer to the uppest layer. This course is really interesting for me, except the exam. I enjoy all the concept story and every mechanism in network protocol.

I think i will not get good mark for this course… i had only 65 in my midterm. Thats unfortunate for me… i missed another two problem at that midterm. Miss understanding about the problem and forget one notation for the formula… hiks, and for the final exam, i do not know yet… hope for better result.
