Adaptive error control code implementation framework for software defined wireless sensor network (SDWSN)

摘要

We propose an adaptive error control implementation framework for software defined wireless sensor network (SDWSN). This scheme exploits the features provided by both software defined network (SDN) and forward error correction (FEC). The framework supports adaptability at both transmitter and receiver. Additionally, the scheme allows using different FECs in different sections of a network or a link. Therefore, the framework is flexible to support heterogeneous wireless sensor networks (WSNs). The adaptability and flexibility offered by the proposed scheme lead to reduce energy consumptions at energy-constrained nodes in WSN. The scheme also exploits energy-constrained properties of nodes in data-centric storage network. The framework offered to use both iterative and non-iterative codes depending on the demand. The use of iterative codes provides more flexibility and adaptability than non-iterative codes due to features provided by iterative codes.
