Abstract

Resource limitations of sensor nodes are the main weakness of wireless sensor networks (WSNs). This problem is difficult to alleviate in traditional ad-hoc networks, where each node participates in decentralized routing process and independently determines the next-hop to send data towards the destination. In that regard, this paper presents WSN architecture based on principles of software defined
networking (SDN), which enables automatic network reconfiguration and optimal management of energy constrained sensor nodes with limited communications abilities. We discuss implementation challenges and the key benefits of softwaredefined WSN design, with a special emphasis on advantages offered by centralized routing algorithms.
