Mobile Phone Programming
multi modality example
•Using GPRS and Bluetooth for cooperation among two terminals for
file sharing
•N70 Mobile Phones
•Symbian/C++ implementation
•Tit for Tat Strategy
•Benefit in the download time
(reduced by a factor of two), the energy (going down to 56%) and
(perhaps) reduced service costs
•Fit with analytical results
