摘要：To provide trustworthy and timely information is the most important tasks of wireless sensor networks. Providing quality of service (QoS) to satisy the end users and matching WSN constraints, has become an significant research work. Nevertheless, majority of research in this area has overlooked the fact that ensures the QoS requires a cross-layer approach straddling through all layers of the protocol stack. Transmission of data in this scenario requires both energy and QoS aware network management in order to ensure efficient usage of the sensor resources and effective access to the gathered measurements. In this paper we highlight the architectural and operational challenges of handling of QoS traffic in sensor networks and to increase the energy efficiencyof the sensors.
