Wireless Sensor Network (WSN) is often outlined as a network of devices. Devices are denoted as nodes, which may sense the surrounding and communicate the data gathered from the surrounding in wireless way. In WSN, the QoS requirements can be determined as performance measurements, such as, delay, reliability, throughput or jitter. The different applications which run on WSN can have different QoS requirements. The dynamic routing algorithm called Integrity and Delay Differentiated Routing (IDDR) is used to differentiate the packets with different QoS requirements. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol has been used to make the clustering and cluster heads are chosen based on the highest energy.
