Conclusions
- Wireless data communication is clearly here to stay
- GSM,CDPD, and CDMAone are widely deployed
- Lots of interest on third-generation wireless: IMT-2000, UMTS
- Wireless communication and portable devices enable new visions (“paradigms”) of mobile computing: (ubiquitous computing, nomadic computing, ....)
- Our research interest: how to facilitate design, implementation and deployment of new and innovative PCS services (resource-intense, multi-medial)
- emphasis on transparently overcoming resource limitations and variances in available resources (power, bandwidth, memory, CPU speed)
- resource variations exist during executions as well as between executions (cellphone vs. palmtop vs. laptop)
- explore mobile code as unifying framework to investigate resource tradeoffs
- current status: developed a few applications, progressing towards building presented architecture, supported by Canadian cellular operator
