Quality of Service Based Error Handling Scheme for Streaming Applications in Wireless Sensor Networks
Download this article as:
In wireless sensor network a Quality of Service (QoS) guarantee is essential for successful delivery of multimedia over network traffic. Challenges in media streaming WSN include high bandwidth on demand, consumption of high energy, quality of service provisioning, data processing/compressing techniques and cross layer design. This paper proposes an adaptive QoS based error handling scheme called QUES, to support in error handling for each variable service sessions based on policy-control rules in order to control transmission errors for different applications such as streaming content delivery over WSN networks using route metrics. A real time test bed approach along with a case study is adopted to test the data error during transmission along with its effective delay and latency.
