This paper investigates the deployment of an SDN-based UAV network providing communication service. Such a network is extremely useful in emergency scenarios. In such a network, the mobility of UAVs is minimal. We consider the placement of the SDN controller and its implications in terms of communication overhead and end-to-end delay of the control packets exchanged between the UAVs and the controller...
This paper presents signaling architecture models and protocol procedures for SDN-based wireless access networks with Media Independent Management (MIM) capabilities. Three models are described for the framework of SDN and MIM controls, which are decoupled interworking, loosely-coupled integration, and tightly-coupled integration between SDN and MIM controls.
In Software Defined Networking (SDN), connections between the controller and the switches are maintained in two ways: out-of-band and in-band. In out-of-band controlling, the control channels are constructed via separate links. However, due to several reasons, sometimes in-band controlling is needed instead of out-of-band controlling. In in-band controlling, the data paths are used for control channels...
Critical Infrastructures such as transportation or energy systems are central to the existence of modern societies. Due to the expected level of performance and developments like the shift towards renewable, fluctuating energy generation in Smart Grids, advanced monitoring and control systems are required for stable operation. This in turn increases the dependence on robust communication technology...
This paper proposes the service discovery and the remote control for Internet-of-Things (IoT) devices based on the Constrained Application Protocol (CoAP) and Domain Name System (DNS). As the number of devices increases, the manual configuration of domain names and services might be unmanageable for users. A legacy DNS Name Autoconfiguration (DNSNA) for IPv6 networks can be used to register the DNS...
