Abstract

In wireless sensor networks (WSNs), packet loss occurs due to congestion. It reduces the lifetime of WSNs due to energy consumed by these transmissions. Successful event detection in Wireless Sensor Networks (WSN) requires reliability and timeliness. When an event occurs, the base station (BS) is particularly interested about reliable and timely collection of data sent by the nodes close to the event, and the data sent by other nodes have little importance. Data generated in wireless sensor networks may not all be alike: some data may be more important than others and hence may have different delivery requirements. We address differentiated data delivery in the presence of congestion in wireless sensor networks. 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.Fair Share rate is calculated in Fairness aware congestion control to improve the energy conservation in WSN. The Fair share rate is allotted to all nodes in the network to achieve reliability and timeliness.
