摘要：Wireless Sensor Network (WSN) is often outlined as a network of devices. Devices are denoted asnodes, which may sense the surrounding and communicate the data gathered from the surrounding in wireless way. InWSN, the QoS requirements can be determined as performance measurements, such as, delay, reliability, throughput orjitter. The different applications which run on WSN can have different QoS requirements. The dynamic routingalgorithm called Integrity and Delay Differentiated Routing (IDDR) is used to differentiate the packets with differentQoS requirements. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol has been used to make theclustering and cluster heads are chosen based on the highest energy. The cluster heads with minimum distance are usedto transmit packets to sink node. The routing algorithm differentiate the packet according to weight present at headerand send the delay sensitive packet along shortest path and data integrity packets along sub optimal path. Data integritypackets are encrypted using homomorphic encryption technique in order to provide security. The performance metricslike energy consumption, average packet drop, packet delivery ratio, queue length are considered. The simulationresults show that proposed method is much efficient when compared with MinRoute protocol.
