Home area network, which is located at the closest position to customer, handles private information of customer in smart grid. Thus, it is considered as security sensitive area in smart grid. And there could be undiscovered cyber security threat and vulnerability of systems. Therefore, it is required to develop the reference model in order to analyze security requirements and enhance the security of home area network. In this paper, home area network centric smart grid logical architecture is proposed to research for security enhancement through analyzing previous reference models. The proposed logical architecture focuses on communication routes and customer affinity.

This paper focuses on a stable clustering scheme for vehicular ad-hoc network. In the vehicular environment, vehicles self-configure the cluster based network for communication between vehicles. Because of the unique characteristics of the vehicle environment such as high mobility and changeable topology, applying the appropriate clustering scheme is very important for maintaining consistent network topology. Therefore, in this paper, we propose a novel clustering scheme considering neighbor vehicles' mobility. The proposed scheme elects a cluster head which has the lowest "neighbor vehicles mobility" value to provide reliable network topology. In the future work, we evaluate the performance of the proposed scheme in terms of rate of topology change, the number of cluster head change and overall network throughput, comparing to existing clustering scheme.

In the competitive era of impending technology, congestion and accidents are still a threat due to various reason, such as high mobility, short link lifetime, and spectrum efficiency in vehicular networks. One of the predominant factors is shortage of spectrum. Hence, the need of efficient management of spectrum in vehicular communication is important. Consequently, the role of cognitive radio (CR) in a vehicular network is essential. In order to exhibit the importance of spectral efficiency, an architecture has been proposed for vehicular communication in CR. The proposed architecture is to minimize both the spectrum inefficiency and spectrum scarcity issues. In addition, multi server queuing model is designed for CR vehicular network. The mathematical analysis shows that CR queuing model is effective in a vehicular network in term of reducing the average waiting time in a system, average waiting time in a queue for a vehicle, and utilization factor of the queuing model.

As the popularity of mobile devices increases, mobile technology is a suitable tool to use for pedagogical purposes. Some practice-based disciplines such as Urban Planning Design or Architecture have issues about how to link theories into practice (for, example, having a tour without large costs). Thus, this paper organized a survey among students to investigate advantages and disadvantages of students' frequently-used map applications. The results indicated advantages of map apps can be used as merits to assist m-learning and disadvantages can be taken as challenges for further analysis.

This paper reviews specific sets of requirements from public sectors and presents open cloud architectures to incorporate these requirements. Cloud computing changes the way an organization consume resources, including hardware, software, and services. A unique set of requirements is extracted from the examination of the existing rules and policies from the public sector to consume these resources. Based on analysis of this set of requirements, this paper proposes an open cloud architecture to build cloud platform and service in public sector.

This paper is an attempt to explore new ways for allowing interaction with mobile devices, such as smartphones and tablets. Mobile devices have become very popular in a relatively short time. Their popularity is mainly due to the portability and until very recently their ease-of-interaction through the touch-enabled screen when compared to older devices. Their portability comes with a trade-off: the small screen through which users can interact with their content. The small size screen can limit significantly the amount of content they can interact with, and also the manner in which this interaction is carried out. In this research, we explore the ways of extending the interaction space of these devices. We assess if, how well, and what mechanisms are possible for enabling users to interact with content located off the screen. In this paper, we report our approach and some early results of experiments we have conducted.

Named Data Networking (NDN) is a novel transmission framework in future Internet. It is a content-centric network. The content is routed based on its unique name, not IP address in NDN. A NDN node broadcasts an interest packet with the requesting named content to NDN. A NDN node has the requested named content. It will encapsulate requested content into data packets and deliver them back to the requesting NDN node. If intermediate nodes are located on the routing path of requesting/replying named content. They will also cache the named content for serving the next same requesting from different NDN nodes. However, multimedia content usually are used the streaming fashion to deliver over the Internet. It is an important issue to design a proper caching mechanism of named multimedia to satisfy the features of multimedia streaming. In this paper, we proposed a partial caching mechanism to temporally cache the named streaming content on the intermediate nodes in NDN. It can provide a better streaming service than the originated caching mechanism in NDN.

Virtual reality (VR) is widely used in the fields of health care. We hypothesis that hand movement with VR simulated scene is similar to actual activity. Nine subjects participated in the study with brain wave monitoring, they used force feedback device to virtual ball catching. We found the brain wave patterns are similar to prior hand movement study, but pattern in the force feedback had longer latency than none force feedback. The results supported virtual reality paradigm can be the part of activity in the real world. We conclude that, movement in the virtual environment and real world had slight difference. Virtual reality can be used as a tool for the motor learning or skill re-acquisition.

It is expected that the Internet of Things (IoT) applications for medical services can be one of the most remarkable solution for taking care of aging population which is in the rapid growth. IoT consists of communications and sensors to accomplish purpose. In the diverse kinds of networks, wireless body area network (WBAN) is a highly suitable communication tool for the medical IoT devices. There are many researches about WBAN and sensor network, which are mainly focused on energy efficiency. However, in this paper, we discuss more practical issues for implementation of WBAN to healthcare service. Therefore, we propose a multi-hop WBAN construction scheme that is consists of 4 operations, the clustered topology setup, mobility support, and transmission efficiency enhancement. As an auxiliary benefit, the proposed scheme achieves an energy efficient feature by reducing the number of total control messages. Extensive simulation shows that the proposed scheme remarkably improves the performance of WBAN.

A Pervasive-computing-enriched smart environment, which contains hundreds of embedded devices coordinated by service management mechanisms, is capable of anticipating intensions of occupants and providing appropriate services accordingly. To acquire high-level contexts, such as human activities, usually involves analyzing and identifying causality and temporal ordering relationships among a bulk stream of sensor readings. However, there are relatively few works investigating this issue. We notice that Complex Event Processing (CEP) is useful for dealing with the issue mentioned above. In this work, we propose a platform for integrating CEP concepts with Per SAM, a service application model for pervasive environments. Applications and experiments are performed to verify the effectiveness of the proposed platform.
