Several mobility support protocols such as the Mobile IPv6 (MIPv6) and the fast handover for the MIPv6 (FMIPv6) have been developed to support seamless handover. However, MIPv6 depreciates Quality-of-Service (QoS) especially for multimedia service applications due to the long handover latency and the packet loss problem. FMIPv6 tries to solve these problems of MIPv6 through handover prediction but the high speed and sudden direction change of vehicles make predictions inaccurate. In this paper, we propose a seamless and robust handover scheme that supports multimedia services in V-WINET/V-ITS. Unlike MIPv6 or FMIPv6 where a new Care-of-Address (nCoA) has to be configured every time when a vehicle meets a new AR (nAR), the proposed scheme continuously maintains the original CoA (oCoA) configured at original Access Router (oAR) and reduces the handover delay caused by the Duplicate Address Detection (DAD). While a vehicle maintains its oCoA, the data packet destined to the vehicle is forwarded from the oAR to the nAR, and finally to the vehicle. At the intersection, the vehicle creates a nCoA to limit the packet forwarding hops between the oAR and the nAR. However, our background DAD scheme reduces the DAD delay at the intersection and also reduces the number of Home Agent (HA) binding updates. Through extensive simulations, we show that the proposed scheme significantly reduces the average handover latency by up to 40%.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128678600","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, carrier frequency offset (CFO), which is mainly due to oscillator mismatches and/or Doppler shift, will destroy the orthogonality among subcarriers and introduce intercarrier interference (ICI) as well as multiple-access interference (MAI) in uplink scenario. Thus, system performance will be seriously degraded. To overcome this problem, it is of great importance to do research on suppression of the interferences caused by CFO. In this paper, we proposed a novel time domain inverse matrix receiver to suppress the interference of multiple CFOs. Compared with the conventional frequency domain direct ZF inverse matrix method, which has high complexity in obtaining the ICI matrix and its inverse matrix, the proposed method has very low complexity in obtaining the interference matrix. Furthermore, the signal after interference suppression is a frequency domain signal. Thus the receiver complexity can be simplified. Simulation results show that this algorithm has almost the same performance to the frequency domain direct ZF inverse matrix method.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129617083","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 IEEE 802.21 working group defines the Media Independent Handover (MIH) standard to provide cross layer control and the information of network environment and services to optimize the handoff process. This work designs and implements the MIH middleware in a Linux platform to provide MIH event services (MIH-ES), MIH command services (MIH-CS) and MIH information services (MIH-IS). Based on the MIH software, we develop a high quality VoIP system which integrates Stream Control Transmission Protocol (SCTP), two MIH-IS based user motion detection (UMD) services and an adaptive QoS playout algorithm (AQP). The MIH services, multi-homing capability and dynamic address configuration extension of SCTP are applied in the VoIP system to perform seamless handoffs. Moreover, AQP adjusts the playout buffer by using the retransmission of partial reliable SCTP (PR-SCTP) and the MIH-ES to reduce the packet loss rate and improve speech quality. The experiment results indicate that MIH can enhance the performance of the handoff process and the quality of wireless VoIP services.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129938851","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 system is quite unique as radio transmission for telemetry services under extreme speed conditions requires not only superior Quality of Service guarantees but must also be able to satisfy these performance requirements under extreme and arbitrarily demanding environments as are typical during any e.g. Formula 1 racing event. Issues related to the Doppler Effect and abrupt changes of the serving HSPA channel are analyzed and addressed here. Conclusions show how a special 3G network design can help to mitigate Doppler Effect impacts. The processes carried out by both the UE and the network to cope with this high speed environment has proven essential to sustain the service in these conditions, as it has the use of suitable receiver Types in the UE. Using derived guidelines and conclusions, a unique system has been developed, built and tested in a Formula 1 environment with very promising results.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130660215","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}
