Such systems often rely on streams of sensor data for intelligent methods of analyzing daily activity patterns and acting on any detected exception conditions. During the initial development phase of one such system a need for defining the requirements for sensor placements, efficient sensor data formats and transmission protocols became apparent, later unit testing and the final validation phases demanded generation of large amounts of suitable sensor test data. In this paper we describe a simulator we developed in order to support both the hardware and software developments of a collaborative project for an assisted living system designed to leverage smart remote monitoring and home security technology. The rationale behind the simulator, its main functions and usage are described and the positive contribution it has made during the initial development and prototyping phases of the above system is presented.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128746449","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}

However, nowadays the traffic on wireless networks has grown to a point where one must take into account the specific characteristics of such networks when setting up a particular TCP implementation on them. Particularly, the TCP performance has been studied over ad hoc wireless networks leading to several new implementations for TCP. The main issue for TCP on ad hoc wireless networks is to differentiate between losses due to congestion and losses occurred at lower network layers. In this paper, we analyze the TCP performance on two different scenarios of static ad hoc wireless networks over the DSDV routing protocol. Our findings show that choosing the right TCP version for ad hoc wireless networks is a key factor for their performance. We show for the scenarios we study, that TCP Reno outperforms TCP Westwood on the average loss rate as well as on the throughput.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129736355","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}

Using GPS Data to Control an Agent in a Realistic 3D Environment 使用GPS数据在现实的3D环境中控制代理

GPS data in itself is too noisy to be used as waypoint data, as even minor errors in waypoints may cause agents to wander into illegal locations or get stuck between obstacles. To improve the inaccurate waypoint coordinates, we created a method based on map matching and A* path finding utilizing a navigation mesh. To demonstrate the competence of our method we compare it with two other methods, which are map matching without path finding and a classifier based GPS averaging without a navigation mesh. We found that using a navigation mesh with map matching and A* based path finding, safe routes can always be guaranteed for the agent even though some unnaturalness is sometimes introduced in the paths.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125591278","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}

Luntovskyy, Josef Spillner","doi":"10.1109/NGMAST.2013.33","DOIUrl":"https://doi.org/10.1109/NGMAST.2013.33","url":null,"abstract":"Systems to combine multiple network and online storage targets with implied redundancy, security and fault tolerance, so-called RAICs, have recently seen renewed discussion due to the growing popularity of convenient Cloud Storage service offerings. For mobile device access to RAICs, less research results are available. A \"smartphone for the future\" with pervasive storage availability should be intelligently and autonomically connected to the Cloud. Such a constellation allows access without great expenses to multiple applications, data, and further resources so that the requirements of the users (security, privacy, safety, pricing, vendor selection, etc.) as well as the functional user objectives are rewarded in the best way. In addition, valuable battery capacities can be saved by selecting appropriate algorithms and parameters and by placing parts of the RAIC integration into the infrastructure. Using the example of distributed data storage, including specific resources services with versatile features such as extended storage capacity, backup, synchronization and collaborative sharing of data, we propose a mobile, energy-efficient and autonomic RAIC integration concept. Its effects are being evaluated with a storage controller on a smartphone.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127837045","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}

Nemecek","doi":"10.1109/NGMAST.2013.34","DOIUrl":"https://doi.org/10.1109/NGMAST.2013.34","url":null,"abstract":"In this paper we present the multiplexing of SIP, RTP, and RTCP streams using one network port. The motivation for this work is to improve and simplify the administration of a SIP-based VoIP session and to enhance the service reliability. This work extends the idea of RFC 5761, which deals only with the merging of RTP and RTCP protocols. The proposed approach resolves existing drawbacks of the session management, which are mainly caused by a usage of three network ports on each side of communication endpoints. Merging all three streams into a single one decreases a network footprint, therefore simplifies the session identification, which is important for a session administration, and improves a passing of firewalls and NAPT devices. As this idea is not strictly RFC compliant this paper defends these violations and depicts its solutions in a way they can be considered as IETF compliant. These statements are supported by tests in a real network environment.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121491849","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 model is based on 3D primitives (triangles, render batches, texels), and hence is hardware agnostic. With the model, a complexity of any given 3D scene can be predicted already at a production phase without access to the actual target hardware. This paper describes how the power consumption model is derived. The model is verified with measurements of real-world content and hardware. With the given hardware, 3D data and given verification scenarios, the model is able to predict the total power consumption with an error ranging from 0.3% to 3.2%.","PeriodicalId":369374,"journal":{"name":"2013 Seventh International Conference on Next Generation Mobile Apps, Services and Technologies","volume":" 43","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114060706","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}
