Congestion Control for a Fair Packet Delivery in WSN: From a Complex System Perspective

Table 1

Complex systems concepts and their equivalences for the proposed WSN model.

Concept	WSN equivalent
Agent	Data packet
Goal	Arrive to the sink with minimum delay
Satisfaction^1	0 if data packet does not arrive to the sink, 1 if it arrives to the sink within minimum time
Behavior	Packets travel across the network to the sink
Friction	An increase on the incoming traffic (throughput), reduces the outgoing traffic (goodput)
System’s satisfaction	Can be evaluated from the outgoing traffic
Mediators	Nodes
Mediator’s role	To execute a (distributed) algorithm that prevents congestion and maximizes the outgoing traffic

¹Notice that satisfaction and friction are user-defined measures and they can change if required.
