In this paper, a novel CSS-FDE approach is proposed to resist the multipath fading degradation, which consists of the cyclic prefix insertion (CPI) designed for the channel estimation, the equalization criterion based on the computational load and the chirp demodulation. Theoretical analysis and simulation results show that this approach can significantly enhance the performance of the traditional CSS in the multipath fading channels. With its low computational cost and high equalization precision, the CSS-FDE can be conveniently applied in practice.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128887634","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}

By utilizing the proposed feature extraction method, the disadvantages of conventional AMC algorithms, such as the feature value is sensitive to outliers in the data, the sample sequence is long and so on could be overcome. The advantage of our new algorithm is we don't need the channel information as a priori.

With the number of vehicles increasing rapidly, especially in cities whose economy is booming, the situation is getting even worse. In this paper, by leveraging the techniques of Vehicular Ad hoc Networks (VANETs) we present a real-time abnormal traffic data dissemination protocol. Specifically, all vehicles running on the same road segment are regarded as a cluster to generate traffic message about this segment. To reduce communication cost, only abnormal traffic data is issued and spread to nearby road segments. By employing event-driven and period combined mechanism, the abnormal traffic messages are disseminated to the vehicles that probably need the messages in time. We propose a distance dependent forwarder selection method to disseminate traffic message. When transmitted inside a cluster, messages are forwarded along the segment from one end to the other based on the least hops principle; while transmitted among clusters, messages are transmitted in epidemic routing mode, which ensure the fast and reliable dissemination. To evaluate the performance of our protocol, we use the real traffic data of Beijing at peak hour. The simulation results demonstrate that our protocol is feasible and efficient for metropolitan-size city.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124319660","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}

These networks do not have any pre-existing infrastructures and users of such a network are relieved from a centralized administration. Since an Ad Hoc network consists of wireless host which may be mobile, its topology changes dynamically. Such an environment requires special routing protocols which are different with those used in fixed networks. A variety of routing protocols capable of adapting Ad Hoc networks topologies have been proposed. This thesis presents studying of five famous wireless Ad Hoc routing protocols which are WRP, DSR, FSR, LAR and DREAM. Simulation results have been used to compare efficiency and effectiveness of above-mentioned routing protocols. The Simulation results show that on-demand protocols are better suited for mobile Ad Hoc networks. They generate less control overhead messages and manage the mobility of nodes more efficiently. However they produce extra delay in acquiring routes which reduces their efficiency in delivering real-time traffic. Also it can be seen that all of the protocols operates much better with the group mobility model than with the random waypoint model.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114993826","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}

Vertical handoff decision plays an important role in heterogeneous networks. In this paper, we propose a vertical handoff decision algorithm (VHDA) to provide ubiquitous access at any time. We consider received signal strength (RSS), available network bandwidth (B), monetary cost (C) and user preference (PF) as the vertical handoff decision criteria. Handoffs are divided into two classes: handoffs initiated by mobile nodes (MNs) and handoffs initiated by attachment points (e.g., base stations or access points). Our proposed algorithm consists of two parts: fuzzy logic based VHDA and cost function based VHDA. For the handoffs initiated by MNs, fuzzy logic based VHDA is used to evaluate the performance of the network and make handoff decisions to choose the most appropriate network. For the handoffs initiated by attachment points, cost function based VHDA is utilized to select the MNs with lower cost values. Then the selected MNs are handed over to relieve heavy load of the current network. A performance evaluation using the integration of WLAN and TD-SCDMA as an example shows that fuzzy logic based VHDA is able to make accurate handoff decisions, reduce unnecessary handoffs and eliminate the ping-pong effect. Cost function based VHDA can make selections quickly, balance the network resources and decrease the probability of call blocking and dropping.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123602583","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}
