In distributed network function virtualization (NFV) environments, the latency can be significantly increased as the length of service function chain (SFC) increases. To reduce the latency, the order dependency allowing parallel processing of service functions (SFs) can be exploited. In this paper, we propose an order dependency-aware SF placement scheme and analyze its advantages and challenges compared...
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...
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...
Recently, many applications for co-operative Intelligent Transportation System (C-ITS) using wireless vehicle communication technology such as DSRC have been developed to improve traffic problems and provide user convenience. Above all, broadcast message sets such as CAM and DENM are very useful for vehicle safety. However, V2X systems must design system parameters in highly congested traffic conditions,...
When designing the waveform and channel for a wideband payload link to transfer UAV's mission data or video, dissimilarly to a narrow C2 link, the multipath propagation impact should be considered as well as time selectivity and large Doppler shift due to UAV high-velocity. For the wideband payload or control link, we propose two candidate waveforms, SC-FDMA with windowing and SC-FDE with RRC filtering,...
