It's a kind of typical combinatorial optimization problems. Ant colony algorithm is good at solving the discrete combinatorial optimization, its well global optimization ability and quick convergence velocity are both necessary to a scheduling algorithm. Moreover, reducing passengers' waiting and traveling time is the main focus of current dispatching algorithms, neglecting the energy consumed by the elevator system. So it's necessary to research on energy-saving algorithms. For the purpose of elevator group's energy-conservation run, the objective function of energy is built, ant colony model for elevator group control system is created, its optimization mechanism is figured out, and convergence of the algorithm is studied in this paper. Simulation results show the effectiveness of the strategy.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123848227","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}

As a new approach to solve this scalability problem, aggregated multicast forces multiple multicast groups to share a common distribution tree. This can be defined as a minimum grouping problem and is proved to be an NPC problem. An ant colony optimization algorithm to tackle this problem is proposed. The number of groups in each aggregated tree is used as an important component when designing the fitness function between two multicast groups. Pheromone update rules are designed based on the fitness function. And the number of common neighbors between a multicast group and an aggregated tree is defined as the selection heuristic information. Simulation results show that this algorithm performs well with various bandwidth waste rates. Compared with a greedy algorithm, this algorithm has better optimization performance, especially when bandwidth waste rate is relatively big.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122492416","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, it selects ‘support vectors’ randomly from the training set, this will effect the result. To overcome this shortcoming of RSVM, an improved RSVM algorithm is presented in this paper. First of all, we calculate the average of relative distance for each sample point in every class; and then use percentile to deal with unbalanced sample and remove the outliers form margin vectors, so the representative vectors as ‘support vectors’ were extracted; finally, we apply the RSVM on these representative vectors. Because we reduce the effect of unbalanced sample and outliers, and apply the representative vectors as ‘support vectors’, so the new algorithm improves the ability of RSVM to classify and the training speed of C-SVM .","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132278059","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}

Existing disparity estimation methods are based on single disparity model and lack the robustness for estimating the real-time view disparities. To overcome this problem, this paper proposes an adaptive disparity estimation scheme which employs adaptive selection of disparity models based on the rate distortion optimization function. By exploiting the information obtained from the disparity models, the proposed technique estimates and compensates the disparities among different views in stereoscopic video coding efficiently. Experimental results show that the proposed technique contributes to improve the accurate of disparity estimation and save the bits spent on the coding.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116409531","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}

Various kinds of solutions have been proposed but they are impractical to be fully applied. In this paper, firstly the wormhole attack topology is analyzed, then cryptography and trust mechanism are combined to design a new multipath trust-based secure routing protocol(MTSR). MTSR based on AODV and SAODV, is distributed and can resist almost all available routing attacks such as discarding, Sybil, spoofing, jamming, flooding, rushing, and especially wormhole attack. Its trust value computation follows the principle of slowly increasing but sharply decreasing, and it does not require any additional equipment, strict assumptions, node location and precise time information.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126427195","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}

This social network complies with the power law distribution and has a small average path as well as a high clustering coefficient. The node degree correlation of MMS is different from other kinds of social networks. The geographical property is also an important factor which affects the users' behavior.
