In this letter we used multicarrier communication to resolve the problem of overloading. Computational complexity associated with optimum maximum likelihood detector (MLD) in wideband code division multiple access (WCDMA) systems is also addressed by using the particle swarm optimization (PSO) algorithm. In the proposed scheme, large number of users in an overloaded system is divided in groups. A carrier is modulated with the composite signal of each group. The carriers of each group are orthogonal to each other. Detection of individual users in a particular group is accomplished through PSO algorithm. PSO algorithm lowers the search space compared to MLD. Simulation results show that PSO algorithm avoids being trapped in any local minima and gives a much faster convergence compared to MLD. It also performed better than other suboptimal detectors.","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":"125074976","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, an authentication watermarking algorithm for H.264/AVC compressed video by modulating CAVLC code words of 4×4 luminance blocks is proposed. During the embedding process, the eligible code words are first identified, and then the modulating rules between these code words and the watermark bits are established. The watermark information can be extracted directly from the encoded stream without resorting to the original video, and merely requires decoding the CAVLC code from bit stream rather than decoding the whole video. Experimental results show that the proposed watermarking scheme can effectively embed watermark information with little bit rate increase and almost no quality degradation.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"35 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":"126988940","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}

It becomes the main challenge to design a network to achieving these QoS objectives. In this paper, a priority-based cross-layer quality-of-service (QoS) scheme for wireless channel and video applications was introduced. The application layer sends an inquiry to examine the link state. Respectively, the link layer feedbacks a trigger to indicate the state of link information. On the other hand, unequal error protection was adapted for retransmission decision. When a packet was dropped, ARQ decision will be make according to the priority-based adaptive QoS of MPEG-4 video streams. Simulation results demonstrate that video processed in cross-layer scheme experiences much better than that of traditional scheme, not only in PSNR but also in visual quality.","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":"126356582","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 local topology of LEO satellite networks provides an advantage of implementing the distributed alternative routing. This micro analysis is developed to construct a congestion control architecture, including the satellite routing, the crosslayer TCP and the gateway control. A distributed class-based alternative routing method, satisfying the different QoS requirements of different traffic classes, is proposed for the satellite routing part to achieve high performance alone for the satellites without connecting the gateway. The performance is evaluated using the Network Simulator, and encouraging results are obtained.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"67 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":"128933994","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 these networks, maintaining inter-actor connectivity is of a paramount concern in order to plan an optimal coordinated response to a detected event. Failure of an actor may partition the inter-actor network into disjoint segments, and may thus hinder inter-actor coordination. This paper presents VCR, a novel distributed algorithm that opts to repair severed connectivity while imposing minimal overhead on the nodes. In VCR the neighbors of the failed actor volunteer to restore connectivity by exploiting their partially utilized transmission range and by repositioning closer to the failed actor. Furthermore, a diffusion force is applied among the relocating actors based on transmission range in order to reduce potential of interference, and improve connectivity. VCR is validated through simulation and is shown to outperform contemporary schemes found in the literature.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"40 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":"116909940","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}

One scheme is the combination of a linear precoder and a minimum zero-forcing VBLAST like decoder followed by a linear equalizer, which is referred to as VBLAST-ICC, and the other scheme includes a linear pre-equalizer followed by a dirty paper (DP) precoder and a DP decoder, which we refer to as DP -ICC. The ICC schemes can provide much convenience for the modulation / demodulation and coding / decoding procedures due to obviating the need for bit allocation. The simulation results show that the ICC schemes exhibit excellent performance at high SNRs compared with traditional OFDM scheme.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"44 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":"128418119","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}
