چکیده
Wireless Sensor Networks (WSN) is a key area of new investments and investigations. It promises a new domain on the way computers and humans interact with our environment. It serves a large number of applications that can be very critical to the extent of saving human life. Therefore, serving reliable and timely information is a key demand to any WSN. Quality of Service (QoS) in WSN discusses some techniques and requirements to provide such reliable and trusted service. In this survey we will trace the efforts to develop QoS-enabled models on WSN networks. First, an introduction to QoS in traditional networks stating its parameters and techniques is presented followed by introductory review of WSN and its unique characteristics such as severe resource constrains ending by a review of QoS implementations in protocol layer stack of WSN.
