Several IPv6 mobility management schemes have been proposed and can provide uninterrupted service. However, these schemes either have synchronization issues or introduce signaling overhead and high packet loss rate. This paper presents a scheme that reduces the handoff latency based on the location and movement pattern of a Mobile Node (MN). An MN can detect its movement actively and forecast the handoff, which alleviates the communication cost between the MN and its Access Router (AR). Furthermore, by setting the dynamic interval in an appropriate range, the MN’s burden can also be alleviated. Finally, by performance evaluation using both theoretical analysis and computer simulations, we show that the proposed scheme can lower the handoff latency efficiently.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116113496","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}

Current manual binning techniques are cumbersome and limited in both the quality and quantity of analysis produced. To address the quality of results, a new framework applying two different sets of clustering algorithms and inference methods are implemented. The two methods investigated are fuzzy c-means with minimum description length inference and k-medoids with BIC. These approaches lend themselves to large scale parallel processing. To address the computational demands, the Nvidia CUDA framework and Tesla architecture are utilized. The resulting performance demonstrated 1-2 orders of magnitude improvement over an equivalent sequential version. The quality of results is promising and motivates further research and development in this direction.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123982920","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 WSANs, sensor nodes are in charge of the sensing task, while the actor nodes take actions in response to the sensed phenomena or the detected event. In order to execute the correct operations, the applications typically have to process the data or messages from the different sensors in the same order. This paper presents a Consistent Message Ordering (CMO) algorithm, which ensures that messages from the different sensors arrive at the different actors in a consistent order. The significance of the algorithm is fully localized, asynchronous and energy-efficient. We prove the correctness of the algorithm, and analyze the theoretical message complexity. And the experimental results show that CMO algorithm improves the performance at least 60% over TMOS algorithm in many situations.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130183212","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 paper proposed a Multi-threaded Multi-home DSM system (MM-DSM) to support both data sharing and computation synchronization in multi-threaded applications whose threads are grouped into bundles and distributed across multiple computers for parallel execution. Globally shared data are rearranged and assigned to different thread bundles based on their access patterns. As thread bundles move around, their hosting nodes will act as the homes of the associated data blocks to reduce communication cost. Programmers can still stick to the shared memory programming paradigm whereas data consistency, distributed lock, false sharing and multiple writes are taken care of by MM-DSM. Experimental results demonstrate its effectiveness and correctness.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129196667","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}

To our knowledge, most of the latest detected large-scale botnets are based on the centralized structure with HTTP or customized protocols. Therefore, centralized botnets detection helps greatly improve control of unwanted traffic. The main contribution of this study is the development of a common detection mechanism aiming at the centralized botnets. In this work we investigate the intrinsic characteristics based on the distributed yet bursting property of the centralized botnets. Our study shows that there exist great similarity and synchronization among the behaviors and the command and control (C&C) traffic of the bots, because the bots are controlled to operate according to the programmed schedule. Firstly we can determine if the groups of flows are suspectable by performing evaluation on the payload similarity and sequence correlation. Further, we will monitor and keep tracking with the collective and simultaneous behaviors of the suspicious groups of hosts. As is shown by conducting experiments, the proposed method can detect and hold back the centralized botnets effectively before they seriously influence the normal operation on the wide-scale network.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128170463","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 define the primitive elements of the language to specify both qualitative and quantitative constraints in synchronization control. A table template is designed to organize those elements as a user-friendly definition interface. We also construct a language parser to generate agent instances which execute a parallelizable pattern matching algorithm to determine satisfiability of synchronization constraints in runtimes of concurrent systems. By applying the concept of staged event-driven architecture (SEDA), we make the implementation of the constraint processing scalable by designing the algorithm into a data-driven and distributed fashion. In this paper a SimSync module incorporated into a variance of Petri-net, Object-Process Network (OPN) is provided.

To improve paging performance for memory-intensive or I/O-intensive workloads, we propose the hypervisor REMOte disk CAche (REMOCA), which allows a virtual machine to use the memory resources on other physical machines as its cache between its virtual memory and virtual disk devices. The goal of REMOCA is to reduce disk accesses, which is much slower than transferring memory pages over modern interconnect networks. As a result, the average disk I/O latency can be improved. REMOCA is implemented within the hypervisor, by intercepting guest events such as page evictions and disk accesses. This design is transparent to the applications, and is compatible with existing techniques like ballooning and ghost buffer. Moreover, a combination of them can provide a more flexible resource management policy. Our experimental results show that REMOCA can efficiently alleviate the impact of thrashing behavior, and also significantly improve the performance for real-world I/O intensive applications.","PeriodicalId":346815,"journal":{"name":"2009 IEEE International Symposium on Parallel and Distributed Processing with Applications","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134190389","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 scientific process requires composition of these resources to solve a specific atmospheric science problem. A challenge is how to harvest data and models for designing and executing experiments in a seamless manner. Moreover, data-intensive scientific experiments with large-scale scientific data processing are iterative, dynamic and human centered. In particular, the atmospheric scientific experiments usually include some fixed steps, such as data discovery, access, preprocessing, transformation, visualization. A web service-enabled workflow system is a flexible tool for accessing distributed scientific data, and executing complex analysis on it. In this paper, we describe a four-layered architecture of the workflow system, which consists of web interaction layer, workflow engine layer, workflow components layer and resource layer.
