Challenges – Tech Expedition Data Packet lost Packet lost Corrupted data Corrupted data Data synchronization Data synchronizationModeling Glacier activity model Glacier activity model Climate model Climate modelTransportation Commute to research site Commute to research site Heavy tools – drilling machinery Heavy tools – drilling machinery

Mobile Networking - Pros Convenience No wires No wires Easier networking between probes Easier networking between probes Better than traditional wired instruments Useful to study volcanic activities and early warning system Tsunami detection

Mobile Networking - Cons Power 3.6V Lithium battery – life 3.6V Lithium battery – life Restricted use of Probes – 6 times a day Restricted use of Probes – 6 times a dayCost Mobile devices Mobile devicesDistance Transmission range Transmission range Data transfer speed Data transfer speed Data transmission water vs. ice

Future Improvement Making probes exchange data among themselves Ad hoc mesh network Helps transmit the data if probe is out of the range from receiver Helps transmit the data if probe is out of the range from receiver Allow probe to report their location Allow probe to report their location

Conclusion Precise prediction of what Earth’s ice will do in future?! Development of Mobile Communication Safety – Alarm system for natural disasters Questions
