In the proposed scheme, the receiving mobile terminal (MT) selection gives higher priority to MTs achieving higher throughput in the next MU-MIMO transmission while reducing signaling overhead, leading to system throughput improvement. The wireless frame setting in the proposed scheme, introducing hybrid frame aggregation method, provides lower frame error rate than acceptable level by using frame size adaptation.

{"title":"A Study of Network Stability on Wireless Sensor Networks","authors":"K. Ishibashi, K. Yamaoka","doi":"10.1109/NGMAST.2015.42","DOIUrl":"https://doi.org/10.1109/NGMAST.2015.42","url":null,"abstract":"In association with recent advancement in wireless communications as well as penetration of wireless devices with sensing, computation and wireless communication capabilities, the wireless sensor networks have become an important research area due to their potential for providing cheap and flexible solutions to data monitoring and device actuation. And, many studies have analyzed routing effectiveness for wireless multi-hop networks and/or mobile ad-hoc networks under conditions that continuous communication and point-to-point traffic flows between nodes inside the network are assumed. On the other hand, our targeted WSNs for data monitoring have some different assumptions such as traffic patterns on data monitoring, restrictive packet existing periods, and network consisting sensor nodes with constrained capabilities. For evaluation of network stability, not only average loss rates are important, but also distributions are relevant, because high loss rates on temporal wireless links would make impossible to ensure reliable management of the targeted application. So, in order to evaluate stability of those networks, novel evaluation metrics are required. In this paper, we address stability of the WSN for data monitoring, propose a mechanism to improve the equitableness of the routes to the central node as the advanced local route reeselection procedure, and evaluate the proposed mechanism by a conditional data delivery ratio with wireless failure.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117181844","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}

Based on this analysis, we find that increasing the line-of-sight (LOS) component can enhance the system performance in terms of the channel estimation accuracy, and the pilot contamination can be eliminated with both usage of very large number of antennas and applying large values of the K-Rice fading factor for the Rician fading channel model. Similarly, the pilot contamination will be eliminated via using large values of antenna and applying large values of m-shaping factor for the Nakagami-m fading channel. In addition, the effect of correlation can be reduced with both large values of the m-shaping factor and the number of antennas.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127362380","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}

In view of the accelerated trend towards consumption of high quality video, power utilization by mobile devices is expected to excessively increase. This paper presents a power and bandwidth efficient resource allocation scheme considering the end user's Quality of Experience (QoE) in the context of mobile video streaming. QoE has become the prime performance criterion for media delivery technologies. The QoE is estimated by an objective online estimation model based on adaptive Fuzzy Inference Systems (FIS). We simulate a mobile video transmission through which we identify the correlation between receiver's signal-to-noise ratio and QoE. Compared to QoS-based techniques, the proposed QoE-based scheme enables to save up to 33.13% in power and grant up to 50% more data bits for transmission.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125983634","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}

This paper presents a novel mobile application called \"Connect and Control Things\" (CCT) which integrates a lightweight IoT framework into smartphones and tablets. The framework is designed to discover & interact with things, reason with M2M data, provide configuration management facilities along with subscription and notification functionalities. The novel capabilities of CCT are: (i) lightweight search engine based dynamic discovery of physical things, (ii) interaction with both sensors and actuators using Sensor Markup Language (SenML) and its extensions, (iii) integrating a lightweight reasoning engine to infer high level abstraction, (iv) CoRE Link Format based configuration management and (v) support for both smart and legacy things regardless of communication technologies. An IoT architecture is presented along with a prototype implementation details for Android powered devices. Uses of the prototype mobile application in home automation scenarios are outlined. The performance of CCT is evaluated in terms of memory requirement, CPU usage and power consumption. Experimental results establish that the overall design and implementation of CCT are lightweight which encourages the adoption of CCT.

Cloud and Energy Management -- Issues and Concerns 云和能源管理——问题和关注

{"title":"Cloud and Energy Management -- Issues and Concerns","authors":"Peter H. Shuttleworth","doi":"10.1109/NGMAST.2015.57","DOIUrl":"https://doi.org/10.1109/NGMAST.2015.57","url":null,"abstract":"The emergence of Cloud Computing has dramatically shaped the provision of computing services to consumers. Global, large scale deployments of Cloud infrastructure services have fundamentally changed the way in which we use IT services today. Businesses are now able to convert capital costs into operating expenses in order to reduce financial risk, which in turn, has resulted in a significant increase in the take-up of Cloud based services. However, this has in turn transferred considerable infrastructure costs onto Cloud Service Providers (CSP). The operational costs of large Cloud Data Centers (CDC) are significant, with the provision of energy a large proportion of this expense. The efficient management of energy, and the concept of Green Computing in general, is high on the agenda for CSPs. Cloud services, with their application in 'Smart Cities', offer an attractive reduction of expenses and resource consumption. This, coupled with the ability to rapidly and dynamically commit computational power on demand, means that the management of energy in CDCs is of substantial concern to cities aiming to develop 'smart' urban growth within their centers. This paper investigates the issues and concerns regarding energy management in Cloud Computing, by reviewing existing published research papers and literature in the field. The paper then identifies a key publication which introduces the concept of a \"Green Cloud Framework' and Virtual Machine Scheduling and Management as a key energy efficiency issue. Finally, the findings of this publication are interpreted in relation to datacenter energy efficiency in general, before identifying areas for further research.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114392935","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}

It is based upon the emergent properties of complex systems, exploiting the concept of swarm intelligence. The benefits brought about by this approach are node simplicity and improved network scalability given very low implementation overheads. Through the co-operative operation of nodes, a network can exhibit emergent self-initialisation and organisation and is adaptive to environmental and structural changes. The protocol was developed using social concepts drawn from the field of particle swarm optimisation, alongside negative feedback concepts from control system engineering. It offers comparable or better performance (in throughput and delay) with lower complexity and less overheads for larger scale networks when compared to the widely used and simple but still very effective IEEE 802.11 CSMA/CA standard.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132384081","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 designed a real-time implicit palm rejection algorithm based on hand model filters and touch characteristics. We focus our approach on accurately determining the context of the touch in real-time to provide users with an experience that is close to natural handwriting as possible. Our algorithm uses a model-based filtering method to define the palm rejection region and automatically adjust to palm-first or write-first scenarios. Our implementation can correctly filter 99% of stylus touches with a low errant touch rate of 0.87%. In summary, our palm rejection algorithm is shown to be comparable or better than most currently available note-taking applications.","PeriodicalId":217588,"journal":{"name":"2015 9th International Conference on Next Generation Mobile Applications, Services and Technologies","volume":"392 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133579940","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 propose a QoE based energy efficient (QEE) model that provides an approximation algorithm and compare with other previously proposed models [18][19]. Furthermore, the model is also compared with non-quality of experience plus non-energy efficient (NQNE) and a quality of experience plus non-energy efficient (QNE) models.
