Under the assumption of decode-and-forward (DF) cooperative scheme, this paper studies power allocation problem in user cooperation networks with two users transmitting to a common destination. Specifically, centralized and distributed power allocation schemes are presented to achieve proportional fairness while maximizing the overall rate of cooperative users. Moreover, we extend the analysis to the scenario that each cooperative user has no channel state information (CSI) about non-adjacent links. Numerical results verify the effectiveness of our proposed power allocation algorithms.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133958593","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}

Many protocols such as AODV and DSR have been proposed; however, they are not energy-efficient without using nodes' location information. In this paper, we propose a Location aided Energy-Efficient Routing protocol (LEER), which is based on nodes' location information. The main aim of this protocol is to reduce the energy consumption and prolong the lifetime of the networks. The simulation results show this protocol achieves excellent routing performance, and the average energy consumption of LEER is less than AODV and DSR.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"49 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132643574","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 quality of service (QoS) requirements of multimedia services are one of the major challenges that need to be addressed by packet scheduling in the LTE system. This paper proposes a new resource allocation technique for real time (RT) video streaming applications in the downlink LTE system. Resource allocation, which is one of packet scheduling techniques, utilizes instantaneous downlink signal to noise ratio (SNR), packet delay and buffer information when determining the amount of radio resources to be allocated to a user. Simulation results show that the proposed technique outperforms opportunistic technique, a resource allocation technique discussed in the literature, by maximizing system throughput, efficiently utilizing the available radio resources and satisfying the QoS requirements of RT video streaming applications at a higher number of users.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132250241","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 cladding of this THz photonic crystal waveguide is silicon material containing periodic circular air holes arranged as triangular lattice, and the material of its core is polythene (PE). The band-gap distribution is studied by plane wave method (PWM), absorption boundary is determined by perfectly matched layer (PML), and dispersion characteristics are analyzed by finite-difference time-domain method (FDTD). Results show that waveguide dispersion is strongly affected by structure parameters, e.g. air hole diameter, spacing between air holes and core radius. The value, slope and zero-dispersion point of waveguide dispersion can be adjusted by changing structure parameters. Better dispersion characteristics could be achieved at higher air-filling factor.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114703162","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}

How to effectively search data and to find out what we need becomes a critical issue. In this work, four affective modes of exciting/happy, angry, sad and calm in songs and speeches are investigated. A song clip is partitioned into the main and refrain parts each of which is analyzed by the tempo, normalized intensity mean and rhythm regularity. In a speech clip, the standard deviation of fundamental frequencies, the standard deviation of pauses and the mean of zero crossing rates are computed to understand a speaker's emotion. Particularly, the Gaussian mixture model is built and used for classification. In our experimental results, the averaged accuracies associated with the main and refrain parts of songs, and speeches can be 55%, 60% and 80%, respectively. Therefore, the method proposed herein can be employed to analyze songs and speeches downloaded from websites, and then provide emotion information to a user.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125520600","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}
