Further development of practical body-worn systems requires compact, low-cost and low-power battery-powered equipment. A versatile wearable network node offering all these features, including a powerful microcontroller for data processing and additional memory for local data logging was designed and implemented. The node allows receive diversity, mitigating the negative impact of fading, which is typically present in indoor propagation environments. Channel measurements are performed for an indoor Non Line-of-Sight communication between two nodes. Mobile-to-base-station as well as mobile-to-mobile links are considered. A statistical analysis of the performance determines outage probability with and without receiver diversity for both link types, showing a significant diversity gain in all cases. Correlation properties, level crossing rate and average fade duration are also determined.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121152835","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 wireless communication technique chosen to enable the data transmission is Visible Light Communication (VLC) due to its numerous advantages. The system consists of a commercial LED-based traffic light as a Road-Side-Unit (RSU) emitter, a transceiver that receives the message from the traffic light and retransmits it to the vehicle behind by using the tail lights, and also a second receiver that receives the message from the transceiver. Measurements exhibit a Bit Error Ratio of 10-7, both for the I2V and V2V, without using any complex error correction codes, which is considered good, even for traffic safety applications. The tests results show that the proposed cooperative system allows the RSU to communicate with vehicles outside the service area by using multi-hop communication.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"170 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113953186","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 this paper, we investigate the effect of the path loss exponent in relation to the carrier sense threshold setting and the traffic intensity. We present a new analysis of the hidden node area in a broadcast network and compare broadcast outage probabilities for various traffic loads and carrier sense ranges. According to our model, the propagation environment (in particular the path loss exponent) has a major influence on performance. The traffic load and carrier sense range also affect throughput. A large attempted traffic load per carrier sense is preferred, since this gives the best performance.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121704762","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}

Here, we will show that the AAM algorithm has a superior performance compared to the FIFO algorithm in terms of the aggregation trade-off in achieving the maximum average throughput with the minimum average delay in wireless networks as the average size of an AAM aggregate packet is larger than that of a FIFO aggregate packet. The analysis is based upon ns-3 simulation and includes operation under lossless and lossy channel conditions which includes the impact of PHY rate adaption scheme.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114444452","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 this work, the fairness provisioning is investigated in a competitive telecommunication field such as the passive optical networks (PONs). Intending to resolve unequal resource allocation in the downstream data delivery, a fair bandwidth assignment scheme is devised and evaluated. The Max-Min fairness concept is applied in order to determine the best effort (BE) bandwidth allocation of each optical network unit (ONU) in the optical line terminal (OLT) side. Simulation results indicate the benefits of utilizing the proposed resource allocation technique in terms of fair bandwidth distribution.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114583883","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 a practical wireless network, these sensor measurements cannot be collected instantaneously and arrive after a certain delay. In a dynamic scenario where the users move around, this delay will render some measurements out-dated and, if not taken into account, have a negative effect on the localization performance. This paper consists of two parts, in the first part we investigate the effect of user movement on the measurement models for ranging. In the second part we use these models to analyze the impact of movement on the accuracy of the position estimate by means of the Cramer-Rao lower bound (CRLB) which bounds the performance of the estimation.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125725951","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}
