Peer-to-peer P2P) overlay networks provide excellent system scalability and high resource utilization, which make it an attractive solution to this problem. This paper considers a hybrid hierarchical P2P overlay network structure that consists of both super and normal peers. The media streaming architecture is built upon a tree structured network of super peers and the tree construction process has a significant impact on the overall system performance. We construct network cost models and formulate a Bandwidth Constrained Tree (BCT) construction problem, which aims at maximizing the number of peers that satisfy a specified bandwidth constraint. We prove that BCT is NP-complete and propose optimal algorithms in two special cases and a heuristic approach in a general case. The performance superiority of the proposed method is illustrated by an extensive set of experiments on simulated networks of various sizes in comparison with existing greedy and degree constrained algorithms.","PeriodicalId":365914,"journal":{"name":"2010 IEEE 16th International Conference on Parallel and Distributed Systems","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130042191","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, method of using a single waist-fixed accelerometer to detect human movement pattern was investigated and evaluated. 10 subjects were asked to run or walk on a treadmill in a regular way. A 5th order Butterworth low pass filter with cutoff frequency 20Hz was designed to filter the acceleration data and denoise the sample. By collecting the velocity from treadmill as label data and the individual’s waist acceleration data, training data set was established. A Bayesian network classifier trained by EM learning algorithm was developed for human movement pattern assessing. Experiment showed that the method could predict the human walking and running state with a considerable accuracy more than 90%. Such accuracy could also be achieved even with a single superior-inferior acceleration feature. The classification of fast speed walking and normal speed one also achieved satisfying result. This indicated that in some application in which walking and running state were only needed to classify could employ the low power, low computational complexity uniaxial accelerometeras the human movement detector.","PeriodicalId":365914,"journal":{"name":"2010 IEEE 16th International Conference on Parallel and Distributed Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114647337","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 application of P2P to areas such as file sharing, collaborative business environment, and distributed computing requires secure communication among the nodes. Cluster-based P2P structure provides an efficient way to do file sharing and distributed computing. A key agreement protocol is a set of communication rules whereby two users establish a shared common key. The shared key is used by users in future secure communications. Supervising services for governing communications between two nodes is an important topic, especially in the area of government affairs. The proposed paper provides a framework for supporting a supervising mechanism in cluster-based P2P networks based on the concept of two-key agreement protocol. This mechanism uses the idea of hash-based two-key agreement protocol to help the nodes in higher level supervise the nodes in lower level for cluster-based P2P communication environment. In the proposed paper, a global cluster head supervises the whole network, cluster heads in each cluster supervise their own clusters’ communications. Security analyses show that the proposed mechanism is secure enough for P2P. Any two nodes within the same cluster generate their common session key by themselves. In the same cluster, no nodes gain this session key except the cluster head. Moreover, there are only two kinds of operations, hash operation and XOR operation, in the proposed mechanism. Hence, the proposed mechanism provides an efficient way to supervise the P2P network.","PeriodicalId":365914,"journal":{"name":"2010 IEEE 16th International Conference on Parallel and Distributed Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123441666","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}
