A Robust Routing Algorithm with Fair Congestion Control in Wireless Sensor Network

There has been a growing interest in wireless sensor networks (WSNs). Considering the limited energy, memory and computational capacity of the sensor nodes, it becomes necessary to ensure rational use of their resources. The fairness and congestion control are also need to be taken into account. It is in this context that a robust routing algorithm with fair congestion control in wireless sensor network (called RRA- FCC) is proposed. RRA-FCC performs a low cost and robust routing based on dividing the monitoring region into several subareas initially. Furthermore, RRA-FCC provides a fair congestion control, which improves the whole network fairness in congestion. The simulation results show that RRA-FCC performs well in the throughput of Sink nodes, energy consumption and the whole network fairness in congestion.
