Location based services of trackers can keep dementia patients safe, but traditional GPS tracker or smartphone based solution device need to be removed for recharging or when taking bath. A water-proof Bluetooth Low Energy (BLE) tag with a CR2302 battery can be used over a year so that it can be worn all the time. By combining BLE technology, smartphones and cloud services provided by Google, we can build a practical location and tracking system with minimal cost.

One of the means to improve convenience of bus users is to introduce a bus location system that provides the users with such useful information as the present bus location and estimated time of arrival at the bus stop. However, since most of the existing bus location systems utilize the cellular network, the communication cost could become quite high. In order to alleviate this problem, we have been proposing a novel bus location system using a wireless sensor network that does not require any communication cost. This paper improves this system further, and offers a method to estimate the bus traveling section without the support of GPS so as to reduce the manufacturing cost of transceivers on board community buses. We have developed a prototype device of the system and conducted on-road demonstration experiments to verify the effectiveness of our proposed system, and it was confirmed that by our proposed system, the present bus traveling section can be estimated with sufficient accuracy.

Energy consumption within communication networks is becoming a more significant problem as the scale of communication infrastructure increases. At the same time, large-scale electricity systems also face problems like transmission loss and energy shortage. Thus in this paper, we base our discussion on a communication system powered by a micro-grid system with renewable energy supplies, which is expected to address these problems well. Then, as a solution to the fluctuating output problem of renewable energies, we propose a transmission control algorithm to directly adapt the system power consumption in response to the fluctuation instead of using batteries as the energy buffer. Through simulation, we prove that our scheme can efficiently use such kind of fluctuating power supplies.

Modern touch screen sensors are capable of detecting and reporting finger presence not only upon contact but also as the finger is approaching the screen. This gives us a wealth of additional information, which to the best of our knowledge, has never been analyzed before. Using these new sensor capabilities, we can see exactly how a user performs gestures starting from the finger's approach through the actual touching of the screen. We decode proximity data which we collect from the mobile phone sensor and extract finger “traces” from each user along with the contact area shapes, which we use to distinguish between the owner and one of the other users. To further improve the classifier's accuracy, we develop a sequential classification approach using a probability ratio test of artificial neural network outputs which makes a decision in minimal time based on predefined accuracy goals. The data not only allows discrimination between users but also detection of their dominant hand. These techniques could be used in many practical applications, such as passive user authentication or personalization. Our experiments show that after just 5 touches, or in 12.6 seconds on average, we can correctly distinguish the primary user from any of 14 other known users using proximity data to model the finger's approach pattern.

The literature lacks theoretical and practical evaluations of Distributed Mobility Management (DMM) schemes which aim to mitigate disadvantages of conventional centralized schemes such as a single point of failure, congestion in home network, and limited scalability. This paper selects Global HAHA, Migrating HA, and Distributed Mobile IP (DMIP) as representative host-based decentralized Internet Mobility Management (MM) schemes, and probes their control and data planes against Mobile IP (MIP) and MIP with Return Routability procedure (MIPRR), using real Autonomous System (AS) level topology data of the Internet. By using different combinations of MM Agent (MMA) placements, random sessions are investigated for host mobility in terms of the total number of hops and the AS load. Comparison of generic results shows that DMIP and Migrating HA outperform the legacy schemes. Further, DMIP overcomes consistency maintenance and scalability problems seen in Migrating HA, maintaining much similar performance, while achieving reliability eliminating an expensive controlling overhead as in MIPRR.

PMIPv6 (Proxy Mobile IPv6) is one of techniques to realize network-based handover. However, PMIPv6 has a problem that it is necessary for all communication of the mobile terminals to pass through a proxy server. Therefore, the network performance is declined in applying the PMIPv6. To approach this issue, we propose a method to apply the OpenFlow technique to the PMIPv6 network. We make experiments to evaluate the communication performance of the proposed method comparing with existing methods. We show that the communication performance of the proposed method is higher than the existing methods.

To reduce the server load and communication cost of machine-to-machine (M2M) systems, sensor data are aggregated in M2M gateways. The C language is typically used for programming the aggregation logic, and the program is embedded into the firmware. However, developing aggregation programs is difficult for M2M service providers because it requires gateway-specific knowledge, and consideration must be given to CPU and memory resources. In addition, modifying aggregation logic requires firmware updates, which are risky. We propose a rule-based sensor data aggregation system, called the complex sensor data aggregator (CSDA) for M2M gateways. Data aggregation is categorized into filtering, statistical calculation, and concatenation. The proposed CSDA supports this aggregation process in three steps: the input, data processing, and output steps. The behaviors of these steps are configured by an XML based rule. The CSDA also supports update modules, which download and overwrite aggregation rules from the server when the modification of data aggregation logic is required. In this case, firmware updates are not necessary. The proposed system is evaluated in an M2M gateway experimental environment. Results show that developing CSDA configurations is much easier than using C because the configuration amount decreases by 10%. In addition, the performance evaluation demonstrates the proposed system's ability to operate on M2M gateways. CPU usage was less than 10%, even with a heavy load, and memory consumption was 128 Kbytes.

We introduce a novel way to search and recommend mobile applications namely, activity-based app search. Keywords used in activity-based app search are terms such as “drinking coffee”, “during a flight”, “cooking with friends”, “driving”. We define context as What, Where, When and Whom. The results returned by activity-based app search are apps that can be used while performing the activity specified in the search (What) at a certain time (When) in a certain place (Where) within a social context (Whom). The use of any of the returned apps and the activity performed by the user will not interfere with each other. For example, activity-based app search for “cooking” will return apps to use while cooking such as Pandora Internet Radio while a traditional search for “cooking” would return apps for cooking such as cookbook apps. Out of all the many challenges that this new search paradigm introduces, we focus on the activity (i.e., What) as it is the most challenging and novel of all four.
