The emerging requirements of large-scale Big Data applications are increasingly affecting server-oriented on-chip computing architectures. In particular, in order to exploit the full potential of highly parallel clustered on-chip interconnects, it is essential to carefully route inter-domain traffic that is one of the primary sources of performance degradation. In this paper, we propose a methodology...
In wireless sensor networks, sensors typically aim to transmit their own readings to the sink node. Constructing an efficient data collection tree is very important since it can determine the lifetime of the given WSNs. In literature, may studies have investigated this issue and proposed algorithms for mobile sink to visit each sensor such that the readings of the sensors can be directly transmit...
In this work, we evaluate performance of home energy management system(HEM) by using three meta-heuristic optimization techniques: Harmony search algorithm (HSA), Bacterial foraging optimization (BFO) and Enhanced deferential evolution(EDE). We categorize appliances into three groups on the basis of their energy consumption pattern. Real time pricing (RTP) scheme is used for electricity bill calculation...
In wireless sensor networks (WSNs) energy balancing and energy efficiency are the key requirements to prolong the network lifetime. In this paper, we investigate the problem of energy hole, where sensor nodes located near the sink or in some other parts of the network die very early due to unbalanced load distribution. Moreover, there is a dire need to utilize the energy resource efficiently. For...

In recent years, large-scale natural disasters frequently occurred in Japan, and each time there occurred physical corruption or failure of the communication infrastructure, congestion of the communication network due to abrupt communication traffic occurred. As a result, it had a great influence on information collection and transmission using the Internet[1]. Also, the information required at the...
In Recent, there have been serious larger disasters, such as earthquakes tsumami, typhoons have around the world. Once disaster occurred, communication network infrastructure is often seriously damaged and network traffic is heavily congested. Particularly since the communication network infrastructure of mountainous and coast areas are not well developed, it is difficult to normally use the communication...
Nowadays mass passenger flow phenomena at different degrees appear in many big cities with large-scale transit network, and those phenomena tend to be regular and complicated. As the most popular public transport in Taipei, Mass Rapid Transit (MRT) is a quite effective traffic tool to relieve the pressure of passenger congestion, especially in rush hours. In this paper, a MRT passenger flow prediction...
The number of behavior-support services for user activities has been increasing lately. To provide a highly convenient service, it is necessary to recognize detailed activities of users. However, in reality, to provide a service in a real environment, some issues need to be resolved such as developing devices required for recognizing activity, handling the vast workload involved in creating features...
On large scale disasters, such as the Eastern Japan Great Earthquake and Kumamoto Earthquake, due to mud slides of cliff and floodwater of rivers, many disaster areas are physically isolated and relief and support activities of victims become quite difficult. The communication means are also destructed in those areas and cannot transmit the disaster information. In order to resolve those problems,...
Wireless rechargeable sensor networks are becoming crucial and important in recent years for the advancement of wireless energy transmission technology. The previous research shown that not all of sensors can be recharged due to the limitation of energy capacity that mobile chargers can carry. If a sensor playing a critical role in a sensing task cannot function as usual due to the exhausted energy,...
Currently, Visible Light Communication (VLC) technology remains a lagging research in the field of UltraWide Band (UWB), due to the inefficiency of data capture and synchronization period. Accordingly, this paper proposes a fundamental designand implementation of data communication of VLC on the MAC layer based on FPGA. This paper includes basic research context, design and implementation of UWB MAC...
Information distribution regarding immediately correlated contents is a big challenge in local communities, such as a university campus. One of the main reasons is that a campus' local network is uncovered by public search engines, and most of the local Web sites in a community operate like information silos. A secondary reason is that the daily activities in a local community are highly dynamic,...
With the rise of Internet technology and development of mobile application, more and more data and information are around us. However, it is not always easy to find the needed information that people want. Therefore, a good recommendation system is required for giving useful or interesting information. To provide useful information for user, a good classification of data is needed for recommendation...
Traditional libraries provide an Online Public Access Catalog (OPAC) as a portal for searches. Unfortunately, the call numbers patrons receive as a response lack the explicit information to guide the patron to the shelf in question. This can lead to a complicated and often time-consuming search, particularly in large multi-level structures. In this study, we developed a panorama-based navigation service...
