Re­search­ing ex­cel­lence

The Star Malaysia - Star2 - - HIGHER EDUCATION -

SUN­WAY Univer­sity Depart­ment of Com­put­ing and In­for­ma­tion Sys­tems as­so­ciate dean and head ( Aca­demic) As­so­ciate Prof Dr Lau Sian Lun re­cently won Best Pa­per at the sixth In­ter­na­tional Con­fer­ence on Cloud Sys­tem and Big Data En­gi­neer­ing held at the Amity Univer­sity, Noida, In­dia, in Jan­uary.

The re­search pa­per ti­tled “Wi- Fi Fin­ger­print Lo­cal­i­sa­tion us­ing Den­sity- based Clus­ter­ing for Pub­lic Spa­ces: A Case Study in a Shop­ping Mall” was co- au­thored with Cor­nelius Toh, a Mas­ter of Sci­ence ( MSc) in Com­puter Sci­ence ( By Re­search) stu­dent, and Yasir Saleem, a re­search as­sis­tant.

The pa­per in­ves­ti­gated in­door lo­cal­i­sa­tion us­ing ex­ist­ing Wi- Fi in­fra­struc­ture and com­mer­cial off- the- shelf ( COTS) smart­phones. Dr Lau pre­sented their find­ings on the lo­cal­i­sa­tion ac­cu­racy us­ing two den­sity- based clus­ter­ing al­go­rithms as well as dif­fer­ent im­prove­ments on the lo­cal­i­sa­tion al­go­rithm.

“I started the re­search in in­door po­si­tion­ing us­ing un­ob­tru­sive ap­proaches back in 2010 with a Masters stu­dent at my pre­vi­ous univer­sity. I wanted to con­tinue when I joined Sun­way Univer­sity in 2013 and was for­tu­nate to re­ceive a grant from Sun­way Group in July 2014 to re­search on Wi- Fibased lo­cal­i­sa­tion tech­nol­ogy,” said Dr Lau, who teaches var­i­ous sub­jects re­lated to pro­gram­ming, soft­ware de­sign and net­work­ing.

On his co- au­thors, Dr Lau said, “Cor­nelius was one of our first class hon­ours BSc ( Hons) in Com­puter Sci­ence grad­u­ates in 2015. I taught Cor­nelius dur­ing his se­cond year and found him an in­tel­li­gent and hard­work­ing stu­dent. He is tech­ni­cally equipped and in­de­pen­dent. Yasir was also one of our MSc in Com­puter Sci­ence stu­dents. Af­ter he sub­mit­ted his MSc the­sis and prior to his grad­u­a­tion, I ap­proached him to join my team. He proved to be a great as­set. Yasir, who also grad­u­ated in 2015, is now a re­search en­gi­neer and PhD can­di­date at Tele­com SudParis in France.

“We were also very for­tu­nate to have a group of un­der­grad­u­ate stu­dents who helped in data- col­lec­tion through­out 2015. Part of the data col­lec­tion soft­ware was de­vel­oped by Tey Kai Yik, BSc ( Hons) in Com­puter Sci­ence grad­u­ate and Ron­ald Chia, a fi­nal year BSc ( Hons) In­for­ma­tion Tech­nol­ogy stu­dent, both from Sun­way Univer­sity.”

The re­search aims to pro­vide an ac­cu­rate tech­nol­ogy that re­lies on com­mer­cial- off- theshelf ( COTS) devices and ex­ist­ing in­fra­struc­ture, such as Wi- Fi ac­cess points and smart­phones. Through self- learn­ing tech­niques, such as a clus­ter­ing al­go­rithm, the sys­tem can build the knowl­edge of in­door lo­ca­tions by col­lect­ing Wi- Fi in­for­ma­tion us­ing smart­phones from the users in that par­tic­u­lar en­vi­ron­ment. This may be­come an at­trac­tive al­ter­na­tive to cur­rent in­door lo­cal­i­sa­tion tech­nol­ogy, if not a brand new so­lu­tion.

Also as one of the in­vited key­note speak­ers at the con­fer­ence, Dr Lau had the op­por­tu­nity to share his re­search on crowd­sourced- based open data for fu­ture smart cities.

Sun­way Univer­sity aims to make a real im­pact in the world. As such, the univer­sity places em­pha­sis on the de­vel­op­ment of its re­search pro­file.

“The Depart­ment of Com­put­ing and In­for­ma­tion Sys­tems un­der the Fac­ulty of Sci­ence and Tech­nol­ogy is con­stantly look­ing out for good and mo­ti­vated stu­dents to join our re­search and projects. For can­di­dates in­ter­ested in pur­su­ing a Mas­ter of Sci­ence ( MSc) or Doc­tor of Phi­los­o­phy ( PhD) at Sun­way Univer­sity, con­tact me to ex­plore pos­si­ble sup­port to be­gin the new jour­ney af­ter your un­der­grad­u­ate de­gree”, said Dr Lau.

The Fac­ulty of Sci­ence and Tech­nol­ogy at Sun­way Univer­sity of­fers stu­dents an ex­cel­lent ed­u­ca­tional ex­pe­ri­ence where they are en­cour­aged to im­merse them­selves in an open aca­demic en­vi­ron­ment through col­lab­o­ra­tions with the aca­demic and re­search team with em­pha­sis on build­ing a strong life­long foun­da­tion for suc­cess­ful ca­reers and last­ing friend­ships.
