In WSN, the sink is only interested in collective information of sensor nodes within the event radius and not in their individual data. It is insufficient for end-to-end network QoS parameters to measure the QoS support in WSNs. We propose event QoS parameters into WSN for non-end-to-end applications. The event QoS parameters reflect the actual need of applications in WSN. Moreover, we present IDQS a queuing algorithm to provide service differentiation for WSNs based on event QoS parameters by setting different packet's lifetime. We find the relationship between packet's lifetime and event QoS parameters. By using the strategy the sink can detect the urgent event reliably and in time. The result of simulation verifies the effectiveness of our approach.
