摘要：Wireless Sensor Network (WSN) comprise of group of tiny sensor nodes that are deployed for collaborative missions such as environmental monitoring, target tracking and surveillance. In this paper we just stress in to Providing QoS in such network mean that set of service requirements to be met by network while transporting a packet stream from source to destination. We look at some of the existing QoS mechanisms, node localization, controlled mobility and data aggregation. We also discuss some problems to provide the QoS, and we then identify some key performance metrics for WSN QoS and outline some mechanisms to achieve QoS in the sensor network. Finally we meet the framework to enhance QoS in wireless sensor network.
