ABSTRACT

Error control mechanism carries vital importance in research aspects of Wireless Sensor Networks (WSNs) due to its limited energy constraints and minimal support for power communication. The survey and analysis provides a comprehensive comparison of FEC / ARQ and hybrid ARQ schemes in WSN. This paper proposes an adaptive QoS routing scheme called SEMU, to support in routing 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. The test results show that SEMU performs to a scalable effective QoS compared to hybrid ARQ schemes and LEACH schemes with minimal latency and delay.
