In order to well maintain in-vehicle communications, it is necessary to evolve protocols for managing communications and, in particular, for granting bus access for real-time applications. In this paper, we describe a demonstration of the multi-channel random access protocol that we have developed for VPLC using OMNeT++. The proposed solution uses a combination of time and frequency multiplexing and consists of two key features: (i) multiple access channels to prioritize transmissions and (ii) a distributed collision resolution algorithm that allows each node to compete for the use of its selected channel. The live demonstration illustrates the contention resolution procedure of in-vehicle communications with different service classes, shows simulation results to validate the advantages of the proposed protocol and provides useful guidelines for developing a robust contention-based protocol for vehicular power line communication systems.","PeriodicalId":410528,"journal":{"name":"2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123970838","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}

For vehicle-to-vehicle communications, this requires information exchange in non line-of-sight (NLOS) conditions due to the obstruction by buildings. In order to overcome the low receive signal-to-noise ratio (SNR) due to NLOS, we consider to place a relay at road intersections to enhance the reliability of communication links. In this paper, we implement a vehicular non-stationary geometry based stochastic channel model for road intersections, which is an extension of an existing highway channel model. The model is verified by comparison with vehicular channel measurements. Using the proposed channel model, we present link level simulation results for IEEE 802.11p relaying at varying transmitter/receiver locations using different channel estimation techniques. The results show that a relay at the intersection is able to greatly extend the reliable communications region. Besides, in the high SNR regime with moderate or high mobility transmitter and receiver, the block type least square channel estimator is the bottleneck that limits the relaying performance. An advanced iterative channel estimator is also simulated, which exhibits robustness against increased vehicle velocities.","PeriodicalId":410528,"journal":{"name":"2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129323907","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}

Though, ensuring the continuity of Line-of-Sight (LOS) of any optical-based applications is one of the most complex scenarios for an autonomous vehicle control, and still remains as an open challenge for Intelligent Transformation Systems (ITS). Exchanging information about the relative directional position of each member of the platoon, together with front and rear facing directions of each vehicle, can be very useful data for building a smooth geometrical-based compensation method, which results in ensuring that any increase in both incidence and irradiance optical angles will never exceed the Field of View (FOV) limitations and regardless of the trajectory shape. This paper propose a tracking alike compensation method of four vehicles equipped with positioning and VLC systems. We have simulated different scenarios related to different trajectories and compensation angles limits. The simulation results show that trajectories influence on the optical incidence and irradiance angles can be compensated efficiently and without deploying any tracking method.","PeriodicalId":410528,"journal":{"name":"2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014)","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121243359","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}

On the two-user multiple-input-multiple-output (MIMO) broadcast channel, when one user with low mobility (called the static user) knows the exact channel state information (CSI) whereas the other user with high mobility (called the dynamic user) does not know CSI, a novel multiplicative superposition signaling scheme could obtain additive degree of freedom. Based on this novel signaling scheme, some detection schemes of the static user and the dynamic user are investigated in this paper. The signal desired by the dynamic user applies unitary space-time code and the signal desired by the static user is designed as the symbol matrix with the full spatial multiplexing, each element of which is a multiple phase-shift keying (PSK) or quadrature amplitude modulation (QAM) symbol. The final transmitted signal is the product of these two signals. At the dynamic user, a non-coherent maximum likelihood detection (NCMLD) is used. At the static user, we propose two hard detection schemes based on NCMLD-ML and NCMLD-Minimum-Mean-Square-Error (MMSE), respectively. To avoid the error-propagation problem in the hard detection schemes, we also propose a low-complexity soft detection scheme based on the conditional expectation and MMSE (CE-MMSE). Simulation results show that the NCMLD-ML scheme outperforms the NCMLD-MMSE scheme and CE-MMSE scheme. Furthermore, CE-MMSE scheme has a better error performance than NCMLD-MMSE in the low signal-to-noise ratio (SNR) region at the expense of higher complexity which is inconsiderable when it is compared with NCMLD-ML scheme.","PeriodicalId":410528,"journal":{"name":"2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133749158","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}

Our simulation framework meets the subset 026 v3.3.0 UNISIG: System Requirement Specification, current ERTMS (European Rail Traffic Management System) specification for high speed lines. We deploy this train control service over different technologies (the standard technology a full stack with X.224, T.70, LAPB and GSM-R) and over TCP/IP next generation telecommunication technologies (LTE, WiMAX, WLAN). By modeling the train control service, we are able to measure how failures or degradation in the communication link affects railroad network availability and operational performance indicators. In our demonstrator, we stress the railroad communication network in different ways and check the behavior of different standardized telecom approaches.

Such periodic transmissions on top of the Dedicated Short Range Communication (DSRC) technology can cause temporal correlated (recurring) collisions, which increase the delay between consecutive awareness updates from a certain vehicle. In this paper we propose to add a controlled random jitter to the nominal CAM broadcast interval at the application/facilities layer. Thus, we aim for making temporal correlated packet collisions more uncorrelated in time and by implication significantly decrease the delay between consecutive CAM updates (update delay or inter-reception time). The benefit of our approach has been demonstrated by simulating a multi-lane highway scenario at different traffic/data load conditions. By adding a random transmit jitter we were able to reduce the amount of correlated collisions by more than factor 10, and by consequence to improve the update delay performance by up to two orders of magnitude.","PeriodicalId":410528,"journal":{"name":"2014 IEEE 6th International Symposium on Wireless Vehicular Communications (WiVeC 2014)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130091091","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}
