Container-based virtualization offers several advantages such as high performance, resource efficiency, and agile environment, which can make IoT device management easy. Though previous studies introduce container-based virtualization to IoT devices, they do not address different network modes of containers and the performance issues. Because the network performance is an important factor in IoT,...
In the near future, Peer-to-Peer (P2P) energy trading is expected to contribute potentially in expanding popularity of small-scale Distributed Energy Resources (DERs). This will arguably create new markets (a new business model). Storing energy for future use is still considered to be an expensive solution. Therefore, establishing a cooperative network among the energy producers and consumers would...
Most of IoT applications include large number of distributed sensors which are interesting in specific geographical area. A large number of IoT entities have multiple relations and dynamic connections with each other. And there are many group communication requirements. Flexible multicast mechanism will be essential in such environments but it is difficult to satisfy verious requirements by means...
Distributed Denial of Service (DDoS) attack has been bringing serious security concerns on banks, finance incorporation, public institutions, and data centers. Also, the emerging wave of Internet of Things (IoT) raises new concerns on the smart devices. Software Defined Networking (SDN) and Network Functions Virtualization (NFV) have provided a new paradigm for network security. In this paper, we...
Making the data plane of a SDN flexible enough to satisfy the various requirements of heterogeneous IoT applications is very desirable for Software Defined IoT (SD-IoT) networking. The network device having programmable data plane provides an ability to add new packet and data processing procedures dynamically to the IoT applications. Previously proposed solutions for adding programmability to the...
Quantum key distribution (QKD) enables two authenticated parties to share secret keys with the ability to detect any attempts to eavesdrop the keys theoretically. Currently, QKD systems can be categorized by its source of uncertainty in nature; single photon or coherent light. As coherent light is harnessed, the overall cost for composing systems drops in general. However, more elaborate post processing...
A unidirectional security gateway is a network system in which data can travel in only one direction. Therefore, the system are used in protecting the safety and reliability of various critical infrastructures. Most of all, it has to be deployed with send and receive transceivers disconnected for one direction to ensure information security. In this paper, we introduce a unidirectional security gateway...
This paper proposes a radio resource management scheme for the multi-RAT (Multiple Radio Access Technology) unit based MHN-E (Mobile Hotspot Network Enhancement) network that provides a millimeter-wave (mmWave) backhaul link of high-speed railway communications. We designed when multi-RAT unit configuration procedure is triggered and how it works, also explained detailed multi-RAT unit bearer configuration...
Existing DR(Demand Response) protocols are designed with the most successful and popular application layer protocol, HTTP. However, due to the rapid development of the Internet-of-things (IoT) protocol, DR messaging technology based on the IoT(Internet of Things) protocol to be used for light energy devices is highly required. In this paper, we extend the existing DR protocol using CoAP which inherited...
The present paper allows to energy information collecting agent for IoT BigData system. Energy management system (EMS) is computer-based platform to monitor and control energy usage at a smart home and building. There are several model EMS — centralized and distributed. This paper suggested hybrid architecture of EMS for efficiently energy management.
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.
With the increase in population and automobiles, the traffic jam in urban areas is becoming a critical issue. These traffic jams especially at the intersections not only increase the delay for drivers, but also increase fuel consumption and the air pollution. The fixed-time traffic light controller is one of critical factors that affect the traffic flow at intersections. This paper proposes a new...
This paper considers a fast fading wireless powered wiretap channel, where an energy constrained information source, powered by a dedicated power beacon, sends a secret message to a legitimate user using the artificial noise (AN) scheme in the presence of a passive eavesdropper. Based on a two-phase time division protocol, the ergodic secrecy throughput is derived. Furthermore, the optimal time-switching...
As the use of IoT devices is explosively increasing in everyday life, OCF has tried to make a specification to give interoperability between IoT devices. In this paper, we propose a new packet format and a new GATT service definition to support CoAP messages over BLE transmission for the OCF specification. Also, OCF resources in the CoAP packets can be exchanged between OCF devices via BLE-GATT protocol...
Quality of Service (QoS) in networking is a way of managing the network resources effectively. QoS has been widely used in traditional network and can also be implemented in Software Defined Network (SDN). Software Defined Network is a new network paradigm that decouples the control plane from the data plane in the network and thus create a network that is scalable, dynamic and easily manageable....
Within the world of wireless technologies, Bluetooth has recently been at the forefront of innovation. It is becoming increasingly relevant for vehicles to become aware of their surroundings. Therefore, having knowledge of nearby Bluetooth devices, both inside and outside other vehicles, can provide the listening vehicles with enough data to learn about their environment. In this paper, we collect...
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...
In this paper, we propose a tele-commanding system model based on delay tolerant network (DTN) for the space communication. For designing this model, we use asynchronous message service (AMS) which is one of application services of DTN. We propose the tele-commanding algorithm, which allows AMS messages to be recognized as a tele-commands. This enables nodes received a tele-command message to conduct...
ATSC 3.0 is well designed based on the concept of all-IP to weave broadcast and broadband together. In order to discover the services or contents delivered through the broadband, ATSC 3.0 defines specific signaling, electronic service guide and automatic content recognition specification. In the case of signaling, the detailed discovering information is provided in the service layer signaling with...
As the IoT environment, in which all objects are connected and information is shared, is being expanded, new services are being applied to the traditional energy services gradually.
