Comparative Study of QoS-aware Network Coding Protocols in WSNs

For Wireless Sensor Networks (WSN), quality of service (QoS) can be defined as the quantity and quality of information that is extracted from data collected in the en-vironment where the sensors are deployed. The level of QoS can be measured by a set of parameters, such as throughput, delay, packet loss, energy efficiency, and reliability. Network Coding (N C) is a promising method that can be applied to solve several shortcomings of WSNs to support QoS. In this paper, a comparative study of some protocols based on NC in WSN is provided. We show that the Network Coding based Duty Cycle Learning Algorithm (NCDCLA), which we proposed in a previous work, outperforms all its predecessors.
