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...
The Tactile Internet refers to the communication networks that have a closed control loop of tactile input and audio and/or visual feedback. Example applications include telerehabilitation and virtual training. To ensure that these applications have unnoticeable latencies and thus satisfied quality-of-service and quality-of-experience requirements, the Tactile Internet needs to guarantee round-trip...
Measurement of visual quality is of significant importance to many image processing tasks. The target of image quality assessment (IQA) is to design effective computational models in order to automatically predict the quality of images in a perceptual consistent manner. We propose a full reference (FR) IQA metric based on information-theoretic IQA framework and passive aggressive learning algorithm...
In this paper, we first propose a Quality of Experience (QoE) evaluation model for dynamic adaptive streaming over HTTP (DASH) services. The proposed model predicts the perceived quality of user based on segment media quality, playback continuity and perceptual quality fluctuations caused by bitrate switching. Large quantities of subjective mean-opinion-score (MOS) tests demonstrate that our QoE evaluation...
An autonomous Internet of Things (IoT) wireless sensor network (WSN) powered by a solar energy harvester with low power electronics is presented in this paper. The power supply is a critical challenge for IoT sensors as many of them normally have limited lifetime due to the battery with limited capacity used. The WSN system, sensor node electronics, and the energy harvesting techniques are all configured...
The recent advancement of industry automation is underpinned by the continuous development of the industrial network. This exponential growth is driving the fourth generation industry revolution (FGIR). To meet the requirement of FGIR, there is an ongoing evolution of industrial network from Fieldbus to Ethernet that has emerged a new opportunity to integrate Software Defined Networking (SDN) technique...
The current privacy protection methods adopted by social network providers rely on restricting users' access rights. They force a user to rigidly divide other users into two categories only: friends and strangers. Based on this classification, they prevent non-friends from accessing to the user's data while provide full access for friends regardless of how close they are to her. However, the level...
In a generic setting subsuming communication networks, resource sharing systems, and multi-agent communities, a client generates objects of various classes carrying class-dependent signatures, to which a server assigns class-dependent service quality. A Fake VIP attack consists in false declaration of a high class, with an awareness that detection of object signature at the server side is costly and...
Smart city is gaining a significant attention all around the world. Narrowband technologies would have strong impact on achieving the smart city promises to its citizens with its powerful and efficient spectrum. The expected diversity of applications, different data structures and high volume of connecting devices for smart cities increase the persistent need to apply narrowband technologies. However,...
As the population of vehicles worldwide continues to increase, more and more parking space is required. And efficient parking management is becoming an important issue. A lot of researches have been done to detect parking lot status, but they usually have limitations including extra sensor devices and hence high cost. In addition, most system is for indoor parking lot because of the management issue...
In a wireless body area networks (WBAN) with integrated sensor hubs, the proposed MAC protocol is a TDMA-based schedule used in active superframe interleaving and beacon shifting defined by the IEEE 802.15.6 standard. It considers the human dynamics and traffic information to meet the different QoS requirements of each sensor, improve bandwidth utilization and reduces packet collisions within networks...
As the data traffic demand increases continuously, LTE Heterogeneous Networks (HetNets) with macro-cells and small-cells seems to be the best solution to enhance the quality of user experience by increasing the coverage and capacity of cellular networks. One of the important challenges in such networks is the user association problem. Several approaches have been proposed for this purpose: based for...
Estimating energy consumption and data rate in LTE networks is a critical issue for some recently proposed applications such as collaborative Internet access and energy-aware cellular data scheduling. In this study, after collecting data via empirical measurements, we provide realistic modeling with respect to LTE signal parameters such as RSRP, RSRQ and SINR. We applied various regression methods...
The dynamic topology of a Mobile Ad Hoc Network (MANET) can introduce operational performance constraints. Cells in the human body use pain to indicate a sense of stress or discomfort. This paper conceptualizes pain in a MANET. As MANET is a collection of mobile nodes that may be acting as a source, destination or relay there is an inherent instantaneous variability in the MANET, and this affects...
Datasets containing private and sensitive information are useful for data analytics. Data owners cautiously release such sensitive data using privacy-preserving publishing techniques. Personal re-identification possibility is much larger than ever before. For instance, social media has dramatically increased the exposure to privacy violation. One well-known technique of k-anonymity proposes a protection...
