摘要：In the Wireless Sensor Network (WSN), nodes are used to observe the surroundings like temperature, humidity, pressure, position, vibration, sound etc. The Quality-of-Service (QoS) is an important issue in order to ensure its effectiveness and robustness. Besides its undoubtedly services and contributions in monitoring systems, WSN’s limited resources can severely degrade the QoS in applications. Congestion in WSN will further reduce the expected QoS of the associated applications. In this case, efficient use of the scarce resources is important to ensure seamless data transmission. The power consumption of a sensor node can be reduced by reducing the rate of packet retransmission which is caused by congestion. In this paper, a selective packet discarding method which is known as Packet Discarding based Node Clustering (PDNC) is introduced. All nodes deployed in the targeted area will be clustered into several groups and a cluster head will be selected at a time. The packet discarding process will then be carried at each node to reduce the number of packets contributing to congestion.
