Topology control is a crucial process for an efficient operation of a Wireless Sensor Network (WSN). The usage of WSNs in the Internet of Things (IoT) emerges new research challenges and novel applications. Recent WSNs proposals enhanced with Software Defined Networking (SDN) practices introduce new innovative network control strategies and protocols based on central control logic. This paper introduces...
Software Defined Networking (SDN) provides a simpler and more efficient approach to manage computer networks. This is achieved by decoupling the control functionality from the forwarding elements, and placing it into a logically centralised controller. This centralised architecture makes SDN susceptible to a range of Denial of Service (DoS) attacks. In this paper we investigate a range of DoS attacks...
