In this paper, we propose two simple and practically feasible countermeasures to address the Route Spoofing and Resource Exhaustion attacks in Software Defined Networking (SDN) scenarios. For Route Spoofing attack, we introduce a new technique called “selective blocking” which blocks an adversary node to use a genuine user's active routes, and for Resource Exhaustion attack, we propose a “periodic...
Nowadays, the wireless sensor networks have critical applications in the environmental monitoring, medical, security, industrial and military fields. The forest fire detection as a monitoring network is one of these applications. Sensors collect dynamic changes such as temperature, humidity, smoke, atmospheric pressure and forward those to a single node or a base station. These informations are sent...
Network Survivability is defined as the ability of a network to support the committed Quality of Services (QoS) continuously in the presence of different failure scenarios. Both availability and performance degradation of a system in presence of failure are integral components of survivability evaluation. Therefore, a composite model is presented for network survivability that includes system availability...
