Energy efficient protocol is very important in Wireless Sensor Networks (WSNs) because the nodes in WSNs are usually battery operated sensing devices with limited energy resources and replacing the batteries is usually not an option. The authors propose a class of algorithms that enforce differentiated routing based on the congested areas of a network and data priority. The basic protocol, called Congestion-Aware Routing (CAR), discovers the congested zone of the network that exists between high-priority data sources and the data sink and, using simple forwarding rules, dedicates this portion of the network to forwarding primarily high-priority traffic.
