Mobile P2P is a more and more interested topic for live streaming in next generation. However, the direct porting of existing P2P application on Mobile IP is difficult to overcome time-critical limitation. Handover under Mobile IP usually leads to overlay failure and session interruption, which lead to long handover delay and intolerable service disruption time. The wireless network has more uncertain dynamics than the wired network, and the dynamics degrade the stable data rate for P2P live streaming. In order to improve the streaming continuity, we propose a cross-layer design to achieve the seamless handover and adjust the playback quality. This article discusses the architecture of present Mobile IP network, and we overcome the challenges to apply P2P service on Mobile IP. The proposed scheme maintains P2P session during IP handover and successfully reroutes packets to the new visited subnet. The motivation is the successful integration of Mobile IP and P2P live streaming, and the goal is the improvement of playback continuity. The simulation results explain that our proposed scheme indeed meliorates the performance of mobile P2P live streaming.","PeriodicalId":117087,"journal":{"name":"2013 13th International Conference on ITS Telecommunications (ITST)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123013001","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}

Although Vehicular Ad Hoc Networks (VANETs) are attracting greater commercial interest, current research has not adequately captured the real-world constraints in VANET handover techniques. Therefore, in order to have the best practice for VANET services, it is necessary to have seamless connectivity for optimal coverage and ideal channel utilization: this comes at the cost of overlapping signals of adjacent RSUs. This overlapping effect can be investigated using concepts such Network Dwell Time, Time Before Handover and Exit Times. In this simulation study we investigate the feasibility and benefits of providing a ubiquitous communication in VANET under different mobile environments. We also study the impact of beacon frequency and velocity on Network Dwell Time, Time Before Handover and Exit Times, which will help us to predict the handover times and thus make proactive handover possible. Therefore understanding handover issues is critical in supporting life-safety applications and services in VANETs.","PeriodicalId":117087,"journal":{"name":"2013 13th International Conference on ITS Telecommunications (ITST)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129775719","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}

Although its practical use is still at early stages, in the last few years research activities have been exploring different solutions to achieve high data rates and reliable links using common LEDs and light sensors. VLC can be used in a variety of applications or end user segments, exploiting already existing lighting infrastructures and thus making VLC a cheap communication system. Among these applications, a prominent case study is that of ITS (Intelligent Transportation Systems), where car headlamps and traffic lights can be used to communicate and fulfill the requirements of road safety applications. This option turns to be particularly effective in short range direct communications to exploit its line-of-sight feature and overcome the issues related to the isotropic nature of radio waves. Recently IEEE undertook standardization activities on VLC, resulting in the IEEE802.15.7 standard, which disciplines PHY and MAC layer services for Visible-light Personal Area Networks (VPANs). This paper shows the development of a VLC prototype based on IEEE802.15.7 standard, using low cost embedded systems as the target platforms. The aim is to get a device suitable to be integrated in existing PANs, or to cooperate with other wireless networks to provide communication services in complex architectures like ITS.","PeriodicalId":117087,"journal":{"name":"2013 13th International Conference on ITS Telecommunications (ITST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129020085","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}

VDTNs assume the bundle layer placement under the network layer. This vehicular architecture can be applied in sparse regions characterized by sparse connectivity, long propagation delays, high error rates, and short contact durations. Although some of the major issues were already solved and several improvements were already achieved, VDTNs still have several issues that should be overcome. One of these issues is related with nodes cooperation and nodes share their own resources to deliver packets from others. This can be a difficult task if selfish nodes affect the performance of cooperative nodes. To detect, identify, and avoid communications with selfish nodes, this paper proposes a reputation system with four different reputation mechanisms and studies their impact on the performance of the network. This reputation system is enforced on two different routing protocols (Spray-and-Wait and GeoSpray). Across all the experiments, it was shown that reputation mechanisms that punish aggressively selfish nodes contribute to an increase of the overall network performance by increase the number of delivery messages and decrease the message average delivery delay.","PeriodicalId":117087,"journal":{"name":"2013 13th International Conference on ITS Telecommunications (ITST)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123814502","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}
