Agenda

4

Offline – Why?

Why do we need a P2P data-sync? In a harsh env like above (Bushfire 2014 – Australia, Vic (Grampians)), there is no internet connection in such remote areas, yet emergency personnel still need to be able to sync data and coordinate rescue effort.

5

Offline – Why?

Our client tells us that these rescue team members need to drive sometimes for 100kms or more to be able to sync data with the server and other devices.

6

Offline – Why?

Another similar scenario that our client has was the ability to sync data across multiple devices for mining field operators. We cannot guarantee any internet connection in a mining field 500+ ft underground.

7

ConnectivityWe cannot assume that internet conn is always available

ReliabilityNo Single point of failure

Time and LatencyLess time to connect and transfer data

CostSave cost on data bandwidth

Improved SecurityYour Data is not accessible by everybody (on internet)

Cross-Platform SolutionsBluetooth LE (4.0)iOS and Windows already support BLE, Android support is upcoming.

Wifi DirectAndroid and Windows already support Wifi Direct, iOS 8 is said to support Wifi Direct too.

Bonjour / ZeroconfigAll three major platforms support zeroconfig (ie: dataSync.tcp.local)

Socket-based NetworkingLower level of networking could be used on all major platforms.

• Stop relying on internet connectivity, spending much money and data bandwidth

• Start building apps that are IoT-ready (AllJoyn).• Many solutions are available for easy P2P

connections• P2P apps are on the rise (Relay Rides $56M, P2P

lending crosses $1B)• There are already many apps that are P2P (ie

Scatter, FireChat)
