This is a implementation of Samsung's patented swam-based content downloading algorithm.

• app.js: contains the code for state diagram and the flow of the algorithm from start to end through all the states.
• broadcast_utils.js: contains the UDP broadcast function.
• device_utils.js: contains the class function for device information that will be shared among the devices.
• udp_server.js: contains the code for udp server which hears the broadcasted info and updates the devices db in every device.

• Include xstate module into this project using npm i xstate

• run app.js in three terminals (3 devices) using:

  • node app.js 3000 1
  • node app.js 3001 1
  • node app.js 3002 1
  • Note: first argument is the port used by the udp server and the second argument is the schedule id required by the device.

• Working demo of the algorithm when the leader selection is done after the grouping.
