EEL 6788 - Advanced topics in wireless networksFocus on urban sensingLotzi B¨ol¨oniSchool of Electric Engineering and Computer ScienceUniversity of Central Florida- Orlando, FLJanuary 9, 2010Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 1 / 16Welcome to EEL 6788 - Advanced topics in wirelessnetworksThis class is a vehicle for students to immerse themselves into currentresearch topics in wireless networks.To clarify a misunderstanding caused by the EEL prefix: this is not anelectrical engineering class. Our perspective is computer sciencecomputer engineering: software, networking protocols, somehardware. We are not interested in antennas, signal processing etc.IEE majors are, of course welcome to the class.Every year, we choose a different topic. Previously we had:IAd hoc networksISensor networksISensor networks from an agent perspectiveLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 2 / 16This year’s topic: urban sensingHow to use the ubiquitous personal devicesIbest example being smartphonesI... but also cameras, watches, personal health monitors etc.to sense our environmentcollect, validate, integrate and securethe dataand deliver it to interested customers, either centralizedor distributed.Also known as participatory sensing, urban computingetc.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 3 / 16Example 1: real time distributed environment monitoringmonitor the level of allergens in areas around the cityuse the cell phone’s sensor to sense the datadistribute the informationIto centralized locations where a map is createdIpeer to peer to people who are interestedChallengesHow do we know that people are interested?What is the motivation in sending?IFree-rider problemLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 4 / 16Example 2: citizen sciencesetting up a study which monitors some environmental valueimportant to the communityIe.g. noise, pollution, vibration caused by trucks, water qualityreal world studies are very expensiveuse cellphones to record data, send it to a central locationChallengesDo we trust the data?ICan we prevent malicious users to distort the values?IWhat about recording errors?IThe issue of motivationLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 5 / 16Example 3: price arbitrageprices of products show a variation across storesstores rely on the fact that comparison shopping is expensiveItimeIfuel costIattention spanuse peer-to-peer networks to record / take a picture of pricesdistribute it to interested parties.ChallengesMotivation, free-riders, trustConflict of interest: do I want to share the deal I found?IIdea: prospect of mutual benefitLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 6 / 16Who is interested in urban sensing?IndustryIMicrosoftINokiaAcademiaIUCLAIDartmouthIMITStartup companiesLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 7 / 16About the instructorLotzi B¨ol¨onihttp://www.eecs.ucf.edu/~lboloniHEC-319, [email protected] (preferred), phone: (407) 243-8256(google voice)Background: BSc in Romania (Tech. Univ of Cluj), PhD Purdue2000, Sillicon Valley startup gig (CPlane, network mgmt), joined UCFin 2002.Research interests:Iautonomous agents, especially coordination, teamwork, culturalmodels, etc.Imobile computing, sensor networks etc.Idistributed systems, scheduling etc.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 8 / 16Class organizationIt is a research class. Goal is to collectively explore an interestingnew domain.Strong emphasis on student participation.The culminating experience (and determining factor of the grade) isthe projectIreal world smart-phone application (Android, iPhone, WebOS etc)Ireal world PC-simulated smart-phone application (eg. Androidemulator)Inetbook appsIsimulation of urban sensing scenarios (YAES etc.)IsurveysProjects with programming components can be 1-2 persons, surveyprojects are 1 person only.Objective: projects as scientific papers.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 9 / 16Class deliverables and gradingPresentation (20%)Project (60%)Homeworks (20%)Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 10 / 16PresentationResearch a topic in urban sensing and present it in class in a 20 minpresentation.IThe goal is to be able to cover more material than if I would have tolecture.IThe goal of the presentation is to teach us.It is usually centered around a single application. I would expect it tobe a bit more than summarizing a paper: you need to read thebackground of the persons, the circumstances etc.Example: CenceMe from Darthmouth. Yes there is a paper whichdescribes the Nokia N900 version. But there is also a later iPodapplication, it might be that there is a small company as well etc.I will put up a series of suggested topics, you can come with your own.Send me the presentation in Powerpoint, OpenOffice or PDF ahead oftime such that I can put it on the webpage.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 11 / 16ProjectReal world application using a smartphone platform (Android, iPhoneetc.)–//– with smartphone emulated on a PC (eg. Android emulator)–//– simulated on a PC (eg. YAES ...)Netbook apps (preferable using peer-to-peer wireless)SurveysProgramming projects 1-2 person, surveys 1 person only.You can get away without programming, but you then you need toread a lot.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 12 / 16Project as paperCheck the website for the exact deliverables of a project.They are structured such that you can send the project to aconference / journal.... and I think you should... consider it as an exercise in a research projectLotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 13 / 16Homeworks: reading assignmentTwo or three reading assignments on papers relevant to the topic.Deliverable: 500 word summaries on the papers.Lotzi B¨ol¨oni (School of EECS) Introduction January 9, 2010 14 / 16Timeline (approximative)January 25: Send your choices of presentationFeb 8: Decide on the project, assemble the teams.IMake sure you have a half page description about the specification ofthe project: what tools are you going to use, what functionality do youexpect to work at the end of the project.March 8: Half time report of the projectISome code should be working... Ideal report: we have done most of thefunctionality, but we need some debugging.IThe final report is already
