Online Social Network(OSN) has become an important platform where people share their life and opinions nowadays, which is followed by security problems especially privacy leakage. Contents generated by OSN users can be browsed and shared by friends or even strangers, which may contain their privacy information and leads to a high risk of privacy leakage. However, traditional DPI mechanism, such as...
The special communication scenario in High-Speed Train (HST) not only leads to an increasing demand of high throughput and continuous multimedia services but also arises many other challenges for cellular network access technology, such as high mobility, frequent and group handovers etc. In order to address above problems, we propose an HST WiFi network application scheme which adopts multi-hop technology...
This paper presents a new coding scheme that considerably increases the efficiency of the channel in multicast setting. Specifically, we study the scenario where three terminals exchange their messages via a satellite gateway. The main difference between the proposed scheme and conventional three-way relay channel is the use of joint channel and network coding. This allows three terminals to transmit...
This paper investigates the wireless mesh IP video surveillance models and evaluates their performance in terms of throughput, End-to-End delay and jitter. Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN...
With more parallel and distributed applications moving to Cloud and data centers, it is challenging to provide predictable and controllable resources to multiple tenants, and thus guarantee application performance. In this paper, we propose an integrated QoS-aware resource provisioning platform based on virtualization technology for computing, storage and network resources. Coarse-grained CPU mapping...
The infrastructure of the Smart Grid communication will require the use of security protocols based on standards of the state-of-the-art. This work proposes a method of parameterization of the IPsec protocol framework, aimed at security of data interoperability in Smart Grid, according to the requirement levels for the security services: Integrity, Confidentiality and Availability, recommended by...
The implementation of the SubBytes (or S-Box) step of the AES algorithm significantly contributes to the area, delay, and power of AES accelerators. Unlike typical logic gate S-Box implementations, we use full-custom 256×8-bit ROMs, which significantly improve performance and efficiency. We implemented a fully-unrolled, pipelined AES-128 encryption accelerator using ROM-based S-Boxes in 65nm bulk...
Wireless Mesh Networks (WMNs) is a promising technology which has a potential of providing inexpensive solutions to a wide range of applications. These networks have been applied in the context of home, community, and enterprise scenarios. The nodes in these application scenarios can be distributed either in a uniform or normal fashion. The key issue is for the network to continuously manage and share...
In this paper, a small area hardware architecture for deblocking filter of HEVC is proposed. To achieve high throughput and small area, an efficient processing order based on a CTU-based pipeline is proposed. The proposed architecture is synthesized in ALTERA Cyclone V 28nm process FPGA with 28.7K gate counts. The simulation result shows that the proposed architecture achieves an area reduction of...
Wireless mesh networks (WMNs) can be considered as a key technology for next-generation wireless networking. However, field trials and experiments prove that the performance of WMNs still below expectations. Therefore, several challenging research issues need to be determined. The routing protocol is one of the important factors to be improved to be robust, scalable, secured and efficient. This paper...
Public buildings and large infrastructure are typically monitored by tens or hundreds of cameras, all capturing different physical spaces and observing different types of interactions and behaviours. However to date, in large part due to limited data availability, crowd monitoring and operational surveillance research has focused on single camera scenarios which are not representative of real-world...
Internet of Things (IoT) and Cloud Computing paradigm is a next wave in the era of computing and it has been identified as one of the emerging technologies in the field of Computer Science and Information Technology. It has been understood from the review reports that integration of IoT and Cloud Computing is in its infantile phase and it has not been extended to all application domains due to its...
This paper deals with a method to measure the quality of Giga Internet service. The existing method needs both remote servers and a client application when measuring Internet quality such as throughput(speed), delay and loss. On the other hand, the proposed method only needs a single-sided application which is installed in a personal computer(PC). The key technique is to use traffic loopback algorithm...
Ever since the conception of the ideology known as the Internet of Things (IoT), our world is slowly approaching the brink of mankind's next technological revolution. The realization of IoT requires an enormous amount of sensor nodes to acquire inputs from the connected objects. Due to the lightweight nature of these sensors, constraints emerge in the form of limited power supply and area for the...
To provide better performance for different applications, multiple ISP subscriptions will be helpful. However, the existing gateways for multiple ISP connections do not meet performance requirements for both UDP and TCP applications. In this paper, we explain how we have designed and implemented a gateway to meet such requirements. Our gateway provides subflow control policies which solve conflicts...
This article consists of a collection of slides from the author's conference presentation. The presentation concludes that Gateware Defined Networking dramatically reduces latency and power and improves throughput in the data center.
The integration of WiFi and WiMAX will allow a seamless connection between users for both connections with larger capacity, higher speeds and mobility access. A special router is needed to allow the interconnection between two different protocol network known as WiFi/WiMAX router. In this paper, we investigate and simulated based on the scenario using OPNET modeler simulation tools and compared their...
VXLAN (Virtual extensible Local Area Network) is an edge-overlay model that uses L2-in-L3 tunneling protocol. It has attracted attentions for multi-tenant datacenter networks. For the deployment of VXLAN in legacy networks, networks can include VXLAN gateways which forward traffic between VXLAN and non-VXLAN environments. This paper proposes the design of VXLAN gateways which are not in servers, but...
Underwater sensor networks (UWSNs) have emerged as an essential technology for various undersea applications. However, the use of acoustic links in UWSNs poses critical challenges in terms of overall delay, energy consumption and low bandwidth, which make the transmission of raw data in large sizes impractical. In our previous work, we employed various nodes (processing nodes, gateway nodes, and sensing...
A high-programming-throughput three-dimensional (3D) vertical chain-cell-type phase-change memory (VCCPCM) array for a next-generation storage device was fabricated. To increase the number of write cells at one time by reducing resistance of bit and source lines, the VCCPCM array includes plate electrodes and double-gate vertical-chain-selection MOSs with 5-nm-thick poly-Si channels. In addition,...
