Spring 2002

Introduction

Tennessee TechUNIVERSITY

USF EEL 4935/TTU ECE 4720SPECIAL TOPICS: WIRELESS SENSOR SYSTEMS


Course Description

USF/TTU - This course satisfies the Senior Design Project Requirement (3 Credit Hours). It can be taken either as a senior level elective OR as the senior design project.

Objectives Hands-on design experience Coverage of emerging wireless and sensor system

technologies Interdisciplinary, collaborative project development (USF

and TTU)



Course Format

Students will work in small teams to design and implement separate sub-systems of a wireless sensor system

Students will also work in larger teams to perform system level work (power bus, system test (including FCC guideline check), packaging/integration, CAE simulation, signal processing/RF link)

Weekly, 1-hour tutorials will cover fundamental and advanced topics in wireless sensor systems

Tutorials will originate alternately from TTU and USF Weekly informal team meetings with instructor to cover subsystem specifics

USF: TBD, Wednesday 4-5, Friday 11-12 TTU: MWF 0900-0950, BN 303 or Telecom Lab

Format for Progress Reports

Brief project description and purpose (1-3 sentences) Objectives for the current reporting period (2-3 sentences) Progress for the current reporting period (2-3 paragraphs; use figures and

graphs where needed - they can be reused in your final project report) Plans for the upcoming project period (2-3 sentences) Revised Project Schedule

Keep in mind that the peer(s) who review your report may not be intimately familiar with your project, so you need to clearly explain the objectives and outcomes.



Peer Review Process

Grading criteria: Clarity of report Level of progress made during reporting period Clear goals for upcoming project period

You are required to turn in reviews for two peer reports that will be assigned to you. You should include brief comments/suggestions and an overall grade of G (good), P (passing), and U (unsatisfactory). Hand-in the reports with your name attached, but NOT written on the report (the reviews are anonymous). Two “U” grades from peers will result in a loss of credit for the student, unless overridden by the instructor(s).

WebBoard

Very user friendly means of putting information on a web-site for the project.

Items that will be posted during this course Reports for peer review (.doc) Tutorial presentations (.pdf) Interim student presentations (.ppt) Any information that needs to be shared within and

between teams Link: http://webboard.tntech.edu:8080/~ee-projects



Assignment 1

Visit the course WebBoard site (USF students: send Frolik name and email address)

Post a Word .doc with a short bio and hours of availability (e.g., reply to TTU Teams/TTU roster post or USF Teams/USF roster )

Learn how to use NetMeeting

BEFORE BREAK: FINALIZE TEAMS FILL OUT MATRICES



Comments

The success of the project (i.e., course) depends on the efforts of all students

Subsystems must work closely to ensure interface requirements are properly defined and met

Need to establish contacts in other groups, ASAP!

Schedule is aggressive: Work early and often!



Alternative Project

The success of the wireless sensor project depends on the timely efforts of all students

A completely acceptable alternative 4720 project is to fully develop four ECE 3760-type labs using newly acquired test equipment.

Any team member not fully participating in wireless sensor project will be removed from project and will be graded on this alternative.
