Although energy is a key parameter in shaping the communication and interaction methods of wireless sensor nodes, the specification of the MAC layer doesn't embed enough information for energy and mobility support. For instance, using the IEEE 802.15.4 beacon frames, a node will be able just to discover whether other peers are powered by mains or are they fully or reduced functional devices. However, sensors nodes are able to gain power by different means including: rechargeable batteries, moving sensor charger, ambient or renewable energy, or a combination of these methods. To address these issues, we propose an extension of the IEEE 802.15.4 frame formats to support mobility and embed new energy powering modes and levels. We discuss how the MAC layer extensions could be used to optimize device discovery and routing processes in IEEE 802.15.4 based wireless sensor networks.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123078179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The target audience are young people between 10 and 12 years old. The rationale for prevention is: first, to help victims of these aggressive episodes to improve behavioral competence to avoid or to deal with future real bullying situations; and, second, to promote in the bystanders empathy towards the victims. The user studies we have performed lead us to the conclusion that the current solution has potential in bullying prevention while being a therapy auxiliary tool. The Serious Game was appreciated by young people who, after playing the game in a continuous time span, reportedly acquired bullying prevention strategies. The BackOffice application, a distinctive feature of our solution when compared to other similar solutions, was also evaluated, and was positively assessed by the psychologists who tried it.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116082847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, an user may be served by a single transmitter under the hard handover or may be served by multiple transmitters simultaneously under the soft handover. Considering all these, an user may have several available options to connect with. We have developed a greedy algorithm which allocates every user to their respective most beneficial link in terms of power requirement and traffic cost. We have compared our proposed algorithm with two existing handoff decision algorithms of which one is based on received signal strength indicator measurements and the other is based on selecting the least congested transmitter. Through simulation we have shown that the proposed algorithm outperforms both these algorithms in terms of user coverage and the average data rate provided to the users.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129252227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Navigation systems, such as car navigation systems and navigation applications in smartphones, are also used in our daily life. By using a navigation system, users can not only find their location but also browse information on nearby attractions such as restaurants or department stores; furthermore, it can tell users the route to lead them to their destination. In these situations users will set their destinations by using the navigation system, but in tourism or for events, users have no idea about the current conditions. On the other hand, organizers will have a hard time trying to control the crowd flow as more and more tourists use their own mobile devices to search for the information they want. In this research, we propose a navigation system to control the crowd flow and lead users to specific destinations or areas naturally by presenting suitable information to them. In this paper, we will explain the experiments performed using the proposed system during an event held in Osaka called \"Osaka Mizube Bar\". The results of the experiment confirmed that the behavior of users can be affected by controlling the rank list that they check on their devices; furthermore, users can be led to a specific destination or area by taking advantage of this function.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134575237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider a setting with several access points, some with excess backhaul capacity, and others in shortage of it, and propose a symmetric approach wherein the distribution of resources is managed between providing and beneficiary access points, without involving the direct participation of the users. We then model the proposal using one-to-one matching game theory and make use of the so-called deferred access (DA) algorithm to reach an optimal, stable solution for the problem. In comparison with random distribution of available backhaul resources, the DA scheme offers significantly better performance in terms of overall throughput, reaching up to 40% when compared to random matching.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115969635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Often they have to rely on special and in most cases expensive hardware devices or can only use a limited range of functions provided by the device. The IAAA project aims at analyzing and modeling users' interaction capabilities in a fine-grained way in order to automatically determine the optimum interaction modalities and devices for the individual user. Later, this information will be used to adapt both user interfaces and interaction modalities to users' needs. IAAA utilizes standard hardware like common smartphones to lower the barriers for people with disabilities and subsequently extends its scope to non-impaired users. This paper focuses mainly on selected user model features that are used to represent a user's individual interaction capabilities. Further, it presents the results of a related initial study.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114375366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some of the activities involve the storage or access of sensitive data (e.g. on-line banking, paperless prescription services, etc.). These mobile electronic services (e-Services) typically require a method to securely identify and authenticate a claimed identity. Currently, e-Services typically use a knowledge-based authentication method by demonstrating the knowledge of a secret (e.g. password), but it is vulnerable to a number of security attacks, e.g. shoulder spoofing and brute force attacks. To thwart the attacks and to make the authentication method more secure, this paper describes our efforts in investigating the benefits of integrating touch dynamics biometrics, into a PIN-based authentication method. It reports the collection of a comprehensive reference dataset from 150 subjects, the extraction of feature data from the dataset, and the classifications and the use of the feature data to identify a user. Experimental results show that, even when the PIN is exposed, 9 out of 10 impersonation attempts can be successfully detected.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116305472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While less than t shares can know nothing about the secret, the problem arises when there are more than t shares. The adversary A can use this to put their share in the last. This paper presents the analysis of consistency in secret image sharing when there are m participants, where t ≤ m ≤ n and adversaries A among the reconstruction subset. The dealer collects t different pixels from the subset t out of the set of m repetitively. The results show that the higher threshold t can produce lower image quality when the adversary A is among of the subset. Hence, the dealer D can visually detect the adversary A when m ≤ 2t -- 1. It shows that the necessity of consistency is sufficient to determine the adversary A.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122572250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
