There can be two type of nodes in network
- Broadcaster node
- Listener node
If Bnode (Broadcaster node) joins:
- Register to DB
- Add listener on Bnode to listen to peer-connection by Lnode.
- On connection with Lnode, call the Lnode with audio stream
If Lnode (Listener node) joins:
- Register to DB
- Add listener on Lnode to listen to call by Bnode.
- On stream available:
- Create audio node and provide this steam as source to it.
###Mongo DB
{
id : String,
type : String,
coords : {
x: Number,
y: Number,
z: Number
}
}####Methods
- insertrNode
- getNearbyBnode
- updateNode
###Audio node
Nearby broadcasters stream are sourced to client using audio node.
####Methods
- setListenerOrientation : Set location of listener.
- listenToAll : Split gains among nearby Bnodes in ratio of their distance to Lnode
- listenToOne : Set gains of all other to 0.
###Broadcaster node
####Methods
- notifyServer : Take broadcasters id and coords as Param
- notifyConnectedPeers : Take array of peer ids and current coords as arguments.
###Listener node
####Members
- threshold : Maximum distance between listener and nearby broadcaster
####Methods
- distance : Same as on server side, calculate distance between two coords.
- isInRange : Return true if distance between source and listener is less than equal to threshold.
- refreshSources : On being notified from broadcaster, call isInRange
- select : On Tap, call listenToOne method of Audio node.
- unselect : On Tap again, call listenToAll method of Audio node.
###Geo location
####Methods
- getDistance : Returns distance between two nodes
- watchPosition : On location change
- Broadcaster notifies server and connected peers about location change
- Connected listeners refresh its source based on new coords.
