Review of MDR Prototype Specs

• Develop Working Java Program to Store and Graph
  Power Consumption Data from iPAQ
• Create a multithreaded chat program to
  wirelessly communicate between multiple iPAQs (or
  PCs)

8
iPAQ Power Monitoring Program

• Use of System Calls to get Hardware Data
• Stores Data in a File
• Can hold multiple data collections
• Use of GNUplot to graph data
• Easily expanded
• Statistical Functions
• Graphing Options
• Robust

Linux
GNUplot
Step 1 PowerCheck class sends apm command to
Linux
Step 2 apm command returns a value (minutes) to
PowerCheck class
Step 3 PowerCheck Class takes the returned
value and stores it in a file
Step 4 PowerCheck executes GNUplot command to
read file and plot data

Wireless Communication Prototype

• Java based Socket Program
• Multiple threads allow several clients to
  communicate with server iPAQ (PC)
• Flexible
• Can accomplish many functions using this means of
  communication
• Will transfer data files, execute commands
  remotely
• Can be used as Instant Messenger program to
  chat with other iPAQs in the local network

12
Flow Chart for Server/Client Program
Step 1 Run server - Create a socket - listen
for Client request
Client 1
Step 2 Run Client 1 - waiting for server
Step 3 Connect Client 1 to server -
Server creates a thread for client 1
Step 4 Run Client 2 - waiting for server
Client 2
Step 5 Connect Client 2 to server -
Server creates a thread for client 2

Problems Encountered

• Inability to Implement Java capability on Linux
  for iPAQ
• Not enough memory to build JRE on iPAQ
• Linux unable to utilize Secure Digital Memory
  Card
• Windows still far more popular than Linux
• Solutions mainly developed for Windows Pocket PC
  Edition
• No cross compiler available working for Java
• Solution Purchase CompactFlash Memory Card
• Allows ample space for JRE installation

15
Road Plan for the Future

• Link Server/Client Program with Power Monitoring
  Program
• Add more functionality
• CPU usage
• Network Performance
• Develop GUI
• Use Hardware Monitoring Tools
• Test Power Consumption under varying conditions
• Test other hardware functions

16
Conclusions

• Feasible to design
• Need additional hardware (i.e. Memory Card,
  Additional iPAQ)
• Able to Meet MDR Specifications
• Follow Road Plan for Next Semester
