As the semiconductor technology advances, which can be seen in the recent spread of smartphones, sensing system including participatory sensing has attracted great attention these days. However, there is few established ways of such a determination of positioning of sensor nodes that enables the optimal measurement with regard to the confidence of interpolation. This study proposes a method to determine the optimal positioning of sensor nodes after one set of measurement at each point, by using the result of interpolation of that set of measurement. In this paper, we will show whether that method is valid by simulating a scaler field and sensor nodes on it.},

To quickly recover telecommunication services in the aftermath of a disaster, the authors proposed a wired and wireless network cooperation (NeCo) system. It achieves rapid recovery and high throughput with wireless bypass routes backhauled by optically wired networks. However, the existing approach only optimizes the locations for a fixed number of recovery nodes. To address this problem, this paper proposes a planning scheme for optimally deploying recovery nodes considering the initial conditions in the target area.},

Understanding forest environment or an ecological system of animals is a key factor for human to coexist with nature and animals respectively. Since periodically sensing these data for human is not efficient, there is a system that in stead of human sensing such data, animals do that. However, there is a problem that such sensed data by animals doesn’t have geological information, and is not shared with other animals properly. Hence, we propose “One-hop forwarding system with geological information”. Concretely, using LoRa, one of LPWAN, we try to solve such a problem. To confirm validation of our proposal, we conducted an experiment in forest. As a result, we verify how our system functions in such an environment.},

abstract = {In light of the recognized need to collect and analyze data to maintain urban development, the “smart city” concept has gained much attention recently. The development of sensing and information techniques has facilitated the analysis of urban mobility to better understand the characteristics of cities. Of the information and data that can be used to characterize cities, transportation data are among the most useful because transportation is so closely related to human and other aspects of urban mobility. In extracting features from automatically collected data, the greatest difficulty comes from the size or complexity of the data set, as these often have too many attributes or indices to analyze. This paper discusses the results of analyses of smart card ticketing authentication logs using nonnegative matrix factorization (NMF). The results present extracted features applicable to assessing various user and station characteristics and dynamics.},

abstract = {It is a significant challenge for telecommunication network operators to immediately restore communication services in the disaster area. To quickly recover telecommunication services in the affected area, this paper proposes a wired and wireless network cooperation system. When the wired communication for leaf nodes of optical tree networks is disrupted, surviving leaf nodes relay packets to and from these nodes via wireless bypass routes. The advantages of the proposed method are promptness and high-throughput, which is achieved with single-hop wireless bypass routes backhauled by wired networks. The optimal routes for wireless links are calculated to maximize the expected throughput by solving a binary integer programming problem. The proposed system is cost effective, because it can be deployed with minimum additional functions for leaf nodes of optical networks. To overcome the limitation of the proposed approach that the distribution of leaf nodes is determined by the demand distribution, additional recovery nodes can be deployed to improve the expected throughput. The numerical simulations including a medium access control level simulation conducting carrier sense multiple access with collision avoidance behavior showed that the proposed method can achieve a higher throughput than an existing bypass routing method, irrespective of the topology of the wired networks.},

By analyzing human mobility data, we can know the activity patterns of a museum visitor, functional compositions of urban spaces, and so on.
However, there is no low-cost way to sensing human mobility easily.
Therefore, we propose the low-cost sensing system for recognizing human mobility using Bluetooth.
Our system obtains a size and a direction of human mobility separately.
Moreover, we show the feasibility of our proposal by two experiments.
The first one demonstrates the feasibility of detecting a size of human mobility.
The second one shows the feasibility of obtaining a direction of human mobility.},

abstract = {環境センサを搭載したモバイルデバイスを持つ一般ユーザが環境センシングに参加するモバイル環境センシングにおいて，プライバシ情報の流出が問題となる．Perturbation技術を用いたプライバシ保護手法では，ユーザが手元のデバイスで偽装処理を施したセンサデータを送信することで個々のデータを秘匿化しつつ，サーバは特定の処理を施すことで偽装処理前の真のセンサデータの統計情報を復元できる．サーバはどの程度復元できているかを把握するために復元精度を推定する必要があり，筆者らは環境情報が時空間的相関に起因して特定のモデルに従うことを利用した復元精度推定手法を提案してきた．本稿では環境情報として大気汚染を取り上げ，筆者らが開発した大気汚染センシングデバイスを用いて行った大規模なモバイル大気汚染センシングについて報告し，得られた実測データを用いて，Perturbation技術の1つであるNegative Surveysの復元精度推定手法を評価する．
In mobile environmental sensing, where mobile users sense environmental variables and send data to a server via mobile devices, there is a risk of privacy leakage from sensor readings. Data perturbation, a privacy preserving method, disguises sensor readings on the user side while allowing a server to reconstruct statistical information, such as data distribution, of original data. Data perturbation has a serious problem in that a server cannot calculate the reconstruction accuracy. We previously proposed a method to estimate the reconstruction accuracy using a spatiotemporal model of environmental variables. In this study, we collect air pollution data with our mobile air pollution sensing device. Using the field survey data, we evaluate our methods to estimate the reconstruction accuracy of Negative Surveys, a data perturbation technique.},

Our approaches to address major challenges related to energy efficiency, collaboration, privacy, ease of deployment, and robustness of communication can be integrated with external systems in a complementary manner to overcome the limitations of current disaster detection and mitigation systems that rely on expensive stationary devices.},

abstract = {In recent years, the reduced cost and increased capacity of memory have resulted in a growing number of buffers in switches and routers. Consequently, today's networks suffer from bufferbloat, a term that refers to excess frame buffering resulting in high latency, high jitter, and low throughput. Although ring aggregation is an efficient topology for forwarding traffic from multiple, widely deployed user nodes to a core network, a fairness scheme is needed to achieve throughput fairness and avoid bufferbloat, because frames are forwarded along ring nodes. N Rate N+1 Color Marking (NRN+1CM) was proposed to achieve per-flow fairness in ring aggregation networks. The key idea of NRN+1CM is to assign a color that indicates the dropping priority of a frame according to the flow-input rate. When congestion occurs, frames are selectively discarded based on their color and the frame-dropping threshold. Through the notification process for the frame-dropping threshold, frames are discarded at upstream nodes in advance, avoiding the accumulation of a queuing delay. The performance of NRN+1CM was analyzed theoretically and evaluated with computer simulations. However, its ability to avoid bufferbloat has not yet been proven mathematically. This paper uses an M(n)/M/1/K queue model to demonstrate how bufferbloat is avoided with NRN+1CM's frame-dropping threshold-notification process. The M(n)/M/1/K queue is an M/M/1/K queuing system with balking. The state probabilities and average queue size of each ring node were calculated with the model, proving that the average queue size is suppressed in several frames, but not in the most congested queue. Computer simulation results confirm the validity of the queue model. Consequently, it was logically deducted from the proposed M(n)/M/1/K model that bufferbloat is successfully avoided with NRN+1CM independent of the network conditions including the number of nodes, buffer sizes, and the number and types of flows.},
