異種混合ネットワークサービス資源協調フレームワーク大石晴夫,矢守恭子,張成,田中良明, 複数の通信方式を組み合わせて通信ネットワークを構築するコグニティブネットワークや異種混合ネットワークにおける利用者の協調による効用，コスト削減，インセンティブメカニズムが研究されている．一方，多様な通信方式のサービスが一般に普及している中で，社会環境の変化に対応した協調行動を取り入れ，これらを統合して利用者にサービス提供するフレームワークは提案されていない．本論文では，交通分野におけるサービス提供の概念であるMaaS (Mobility as a Service)に注目し，MaaSのコンセプトを取り込んだSHaaS (Sharing framework for Heterogeneous network as a Service)を提案する．SHaaSにおける事業者と利用者の間のリソース共有により，利用者の効用と事業者の収益の向上を目指す．SHaaSのアーキテクチャ，料金モデルを提案し，モデルに基づくシミュレーションにより有効性を評価した．従来のサービス提供形態と比較して，特にリソース不足の条件下における高い有効性を示した．, 電子情報通信学会

通信ネットワーク故障頻度とユーザ効用の関係を用いた回線リソース配分におけるオークション適用大石晴夫,矢守恭子,張成,田中良明, 近年の通信ネットワークの汎用化，アプリケーションサービスの浸透，通信品質に対する料金議論など，通信サービスにおける市場環境が大きく変化している．アプリケーション利用視点の利便が重要となり，アプリケーションを快適に利用可能な通信品質のサービスを，ユーザの望む適切な料金による提供が求められている．従来，通信品質の帯域に対する多数の研究があるが，信頼性に対する検討は少ない．通信サービスの故障が社会インフラに与える影響が拡大し信頼性の観点は重要となっている．そこで，通信サービスの信頼性がユーザ効用へ与える影響に注目して，通信サービスの故障発生時におけるユーザ全体の効用総和を評価する．本論文では，故障頻度に対するユーザ効用のWTP (支払意思額：Willingness To Pay)及びWTA (受取意思額：Willingness To Accept)の関係を活用して，ユーザ間で回線リソースのオークション取引を行う方式を提案した．単一区間及び複数区間に対する適用評価によりユーザ全体の総効用への有効性を示した．, 電子情報通信学会

Incentive Mechanism Design for Crowdsourced Indoor LocalizationLi Wei; Cheng Zhang; Liu Zhi; Tanaka Yoshiaki, Wi-Fi based indoor localization systems require to construct a radio map by site survey.
,The process of site survey is time-consuming and crowdsourcing is one feasible option to tackle this issue.Meanwhile, privacy protection has drawn concerns from both industry and academia. In this paper, we propose two incentive mechanisms to stimulate mobile users (MUs) to contribute indoor trajectory data for crowdsourcing-based indoor localization with differential privacy to prevent MUs’ privacy leakage. The
,first mechanism considers fixed reward for MUs and incomplete information where each MU’s sensitivity level of the data privacy is unknown to the crowdsourcing platform (CP). The interaction between MUs and CP is formulated into a two-stage Stackelberg game to maximize MUs’ utility and CP’s profit. The second mechanism jointly considers the variable reward for MUs and assumes CP knows each MUs’ sensitivity level of the data privacy. A demand function is used to model the relationship among CP, MUs
,and service customer (SCs). The optimization problem of CP’s profit is studied to show the impact of the price fluctuation. Comprehensive simulations

Intra-Domain Video Caching in Content Centric Network with Normalized PopularityLiu Zhi; Gu Bo; Zhang Cheng; Ji Yusheng; Tanaka Yoshiaki, Recently Content Centric Network (CCN) is proposed as an alternative of the future network architecture since the current TCP/IP based network is suffering from the usage of IP. The routers in CCN have the caching abilities and the caching strategies affect the system performance greatly. Popularity-aware video caching draws much attentions due to its good performance, and the popularity is calculated based on the number of requests at the video content level. In this paper, we normalize the video popularity when we design the caching policy by taking the video size into consideration and the simulation results show that the proposed scheme achieves better performance comparing with the state-of-the-art caching policy in terms of server hit rate.

Pricing in Pay-per-View Video System for Content Provider Profit MaximizationLiu Zhi; Gu Bo; Zhang Cheng; Wang Xiaoyan; Ji Yusheng; Tanaka Yoshiaki, Pay-per-view video is now becoming a successful business model which charges every video subscription. The content provider's profit is subscription fee paid by users minus maintenance cost and transmission fee paid to network service provider. Given content provider's capacity is limited, and video requests vary in time domain, how to price the different video to maximize the profit is important for content provider. In this paper, we targets the pay-per-view video system, where the same video at different quality levels are provided for subscribers. A profit optimization problem is formulated taking the system cost into consideration. Simulation results show its superior performance over the scheme without applying the pricing schemes. We can also observe the optimal capacity the content provider should provide in typical situations.
