2. In stadium, e.g a football match, some friends invite you to participate in voting for best player of the match.

3. Motivation and requisites
A group of connected handheld device users wants to vote for a certain event: best player, best favorite song,… based on a given list of candidates.
There’s no centralized device to calculate voting results. All is totally distributed computing.
After a while of iterations, each device has the similar voting results.
Requisites:
Devices participating in voting form a connected graph.
Disconnected sub-network will only have local voting results based on votings of its nodes.
Device only exchanges messages with its one-hop neighbors.
Old voting applications: Online voting, voting by SMS message.

4. Solution proposal Using: Message passing mechanism.
Asynchronous Distributed Averaging algorithm.

5. Thank you!
