Software Defined Wireless Sensor Networks (SDWSN): A Review on Efficient Resources, Applications and Technologies

Wireless Sensor Networks (WSNs) play a greater role in short range communication networks. Their application adoption to mission critical systems has increased tremendously in the past decades, due to their deployment simplicity and reasonable implementation costs. However, these technologies have a number of limitations subsequent to their computing capacities. Hence a lot of past research approaches have tried to improve their capabilities in terms of processing, communication, resilience, etc. One approach is to implement WSNs that support some level of Quality of Service (QoS) guarantee in their applications, since it is difficult to provide the desired QoS results on them due to their dynamic architectural nature. However, this is difficult since efficient resource management is key to achieve the desired QoS in WSNs. This paper provides a review on QoS provision in WSNs particularly for mission critical applications. The review focuses on QoS metric implementation, QoS challenges and improved communication opportunities in WSNs. The paper, further proposes Software Defined Wireless Sensor Networking (SDWSN) strategies for efficient resource management and guaranteed QoS support to improve network performance. The proposed strategies are aimed at simplifying QoS provisioning for these constrained technologies using programming methods to advance WSNs applications and their implementations.
