The most famous ones are PageRank and HITS. PageRank uses probability of a random surfer to visit a page as the score of that page, and HITS instead of produces one score, proposes using two scores, authority and hub scores. In this paper, we introduce a new link structure ranking algorithm for trading network based on the differences between trading network and WWW network in the links addition process, a process that known to be the foundation of PageRank and HITS formulation. In the last section, we describe the using of proposed algorithm as a tool for network clustering in addition to its original function as a ranking method.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"73 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121130683","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}

Most of the work has been done in simulation, because a simulator can give a quick and inexpensive understanding of protocols and algorithms. However, experimentation in the real world are very important to verify the simulation results and to revise the models implemented in the simulator. In this paper, we present the implementation and analysis of our testbed considering the Link Quality Window Size (LQWS) parameter for Optimized Link State Routing (OLSR) protocol. We investigate the effect of mobility in the throughput of a MANET. The mobile nodes move toward the destination at a regular speed. When the mobile nodes arrive at the corner, they stop for about three seconds. In our experiments, we consider two cases: only one node is moving (mobile node)and two nodes (intermediate nodes) are moving at the same time. We assess the performance of our testbed in terms of throughput, round trip time, jitter and packet loss. From our experiments, we found that throughput of TCP was improved by reducing LQWS.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121442535","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}

Our aim is an implementation in a modern object oriented programming language with generic data types, as it is provided by Java programming language. The proposed middle-ware uses a distributed list for the communication of the reduction bases and a distributed thread pool for running the reduction engines in different computers.

Existing service composition methods can hardly meet the requirements of dynamic characteristic and heterogeneity in pervasive computing environment. In this paper, we propose a parameter-based service model to accurately describe pervasive services. Based on the model, pervasive services are aggregated in a two-layer graph according to both semantic and syntactic information of the input and output parameters. Moreover, we design a novel service composition scheme to accomplish the user task while satisfy the QoS requirements. Both theoretical analysis and simulation experiments show that this service composition mechanism is effective in pervasive environment.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122610465","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}

Future interfaces should provide features that people are willing to use computers or, more definitely, computing capabilities. A pleasant nature would be the key to success.In this paper we present a multi-dip interface that makes use of total internal reflection (TIR) as a technique for sensing hand gestures under water in a tub. The water also serves as a display of computer-generated information. Neither lighting conditions in surroundings nor graphic images being projected on the water interfere with hand region detection. The system gets true hand gesture information at high spatial and temporal resolutions. Besides, the depth position of a fingertip dipped in the water can be obtained as well as its spatial position. Application of the multi-dip interface to drawing, language learning, and some others is presented.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122684488","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}

Central aspect is data locality. First, we investigate the impacts of good and bad data locality by modifying data accesses. Next, we study the impact of multithreading with respect to data locality based on the data-parallel programming approach. The level of parallelism is increased by assigning multiple threads onto one core in order to hide processor stalls caused by bad data locality. We measure the impacts of data locality and multithreading in terms of execution times and bandwidth for synthetic micro-benchmarks, a matrix multiplication kernel, and an application from Bioinformatics. The results indicate that substantial performance improvements can be obtained with minor effort by utilizing multithreading.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122883862","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, we would like to discuss how multiples source peers deliver multimedia objects to receiver peers in a streaming model so that enough quality of service (QoS) required is supported in presence of QoS change. A multimedia object is realized in a sequence of primitive objects which are units of transmission at the P2P overlay layer. The receiver peer is required to receive primitive objects of the multimedia object with enough QoS, e.g. no primitive object loss. We discuss types of multi-source streaming (MSS) models where a receiver peer can receive primitive objects of a multimedia object from multiple source peers which can support enough QoS.There are serial and parallel types of MSS models. In the serial MSS model, a receiver peer receives each primitive object from one of the source peers at a time. If a current source peer is expected to support lower QoS than required or not to support a succeeding primitive object, another source peer starts sending primitive objects. In the parallel MSS model, multiple source peers in parallel send primitive object units to the receiver peer. A primitive object is redundantly sent by multiple source peers or non-redundantly sent by a source peer. Here the throughput and reliability can be increased.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131469875","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 challenge of this problem concerns the big heterogeneity of the multimedia indexation algorithms and the weak semantic aspect they address. Our solution considers a generic interface for the indexation algorithms, an implementation as Web services, as well as a semantic description in terms of WSMO (Web Service Modeling Ontology) of their functionality and orchestration. Original contribution of the article concerns the idea of organizing the various multimedia metadata types into a generic structure,used to express the user queries, the algorithms' generic interface, as well as the algorithms' WSMO metadata. This approach facilitates the definition of algorithm combination rules, and enables the reduction of the multimedia retrieval task to a metadata matching process.","PeriodicalId":377538,"journal":{"name":"2009 International Conference on Complex, Intelligent and Software Intensive Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121838462","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}
