Wireless Sensor Networks (WSNs) are used in variety of fields which includes military, healthcare, environmental, biological, home and other commercial applications. The adoption of WSNs by specific applications that require complex operations, ranging from health care to industrial monitoring, has brought forward a new challenge of fulfilling the Quality of Service (QoS) requirements of these applications. However, providing QoS support is a challenging issue due to highly resource constrained nature of sensor nodes, unreliable wireless links, dynamic network topology and distributed architecture. They explore QoS challenges and perspectives for wireless sensor networks, compare the current QoS research issues and classify the state of the art QoS-aware protocols to understand the properties and limitations of existing protocols.
