By choosing the route with the minimum value of the proposed “Route Assessment Index”, the selected route is ensured to have high throughput with link's reliability. Also, link bottleneck could be avoided in the chosen route. Hence, the packet drop rate is also decreased. The correctness of the proposal is proven and the simulation results show that our new metric provides an accurate and efficient method for evaluating and selecting the high throughput route in Multi-Rate Ad-hoc Networks.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124900189","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}

We consider a joint optimization of association control and beamforming to maximize a system-wide utility function as a means to balance the load across multiple cells. The beamforming weight vector can be adapted as the channel status varies, but it is not practical to change the user association from a cell to another at the same frequency. Accordingly, we propose algorithms to adapt the beamforming weight vectors according to the channel status variation during the runtime while the association control and the beamforming policy, affecting the runtime beamforming weight vector determination, are selected in a longer time scale. Simulation results demonstrate that the proposed algorithms significantly improve the system-wide performance compared with legacy schemes by balancing the load.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114078816","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 existing software router systems may utilize the cluster structure of multiple machines or GPU systems. Especially, Packet Shader, which uses GPU to exploit GPU's extensive parallelism, shows higher performance compared to other existing software routers. However, Packet Shader does not utilize the memory architecture in the GPU system. Basically, GPU has different types of memories such as constant, texture, and global. Since different types of memories show different memory access performance, we propose a unique index architecture for the forwarding table by exploiting the memory architecture of the GPU system. Through a preliminary evaluation, we show that the forwarding table lookup using GPU can outperform the CPU only system.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114924363","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}
