Genetic Algorithms and Simulated Annealing have been used to solve many combinatorial problems. their results are proven to be efficient in solving such problems. the running time of these techniques is generally less than the running time needed to find the optimal solution. However, in very large-scale problems such as sensor deployment, their running time is extremely high. In this paper, we introduce several parallelization methods to speedup the genetic and simulated annealing heuristics used for the deployment of sensing devices on a field with differential security/surveillance requirements. the parallelization methods are classified into two categories: slave based, and master based. We implemented these two categories using iteration division, and chromosome division. A large number of experiments were conducted on a PVM cluster with 14 nodes to show the speed up and efficiency of these parallelization techniques. © 19th international conference on parallel and distributed computing systems 2006, pdcs 2006.

this paper presents an analysis of the parallel binary merge sort algorithm and a comparison of its behavior in a generalized multiprocessor framework and a simplified Grid Environment. Based on the well known method of Bitton et al. (see [1]) we develop a concise but comprehensive analytical model. © 20th international conference on parallel and distributed computing systems, pdcs 2007. All rights reserved.

Availability of the service delivered by cloud providers is one of the most important QoS factors of the service level agreements between providers and customers. Since current Infrastructure-as-a-Service providers use virtualization technology to manage data centers, virtual data centers (VDCs) have become a popular infrastructure for cloud computing. In order to study the service availability, a stochastic activity network (SAN) model is presented in this paper. the proposed SAN model can be appropriately used to investigate the impact of different characteristics and policies on service availability of VDCs.

DNA computing is a new method for computation using the technology in molecular biology. the enormous parallel computing ability of DNA computing brings new opportunities and challenges to the development of cryptography. DNA cryptography is a cutting-edge sciences which combines classical cryptogram and molecular computing. Finite field GF(2(n)) is one of the most commonly used mathematic sets for cryptography. this paper proposes a parallel molecular computing system to compute the modular-multiplication, an operation combining multiplication and reduction, over finite field GF(2(n)). the operation of reduction is executed after the completion of the operation of multiplication. An instance of computing modular-multiplication is introduced to show the details of our system. the time complexity is theta(n) and the space complexity is theta(n(2)).

Because much interest in spatial database in cloud computing has been attracted, studies on preserving location data privacy in cloud computing have been actively done. However, since the existing spatial transformation schemes are weak to proximity attack, they cannot preserve the privacy of users who enjoy location-based services from the cloud computing. therefore, a transformation scheme for providing a safe service to users is required. So, we, in this paper, propose a new transformation scheme based on a line symmetric transformation (LST). the proposed scheme performs both LST-based data distribution and error injection transformation for preventing proximity attack effectively. Finally, we show from our performance analysis that the proposed scheme greatly reduces the success rate of the proximity attack while performing the spatial transformation in an efficient way.

Scientific workflow applications generally require various levels of computing power over the course of the execution. the applications often take advantage of Cloud computing due to its cost-effective, pay-as-you-go pricing model. However, the scientific workflow executions must be planned wisely in order to minimize the total cost of resource usage. In addition, the lateness of completing some workflows may result in a high penalty cost. In this paper, the scheduling algorithm based on GA and PSO is proposed to optimize the workflow execution. the experiment to evaluate scheduling efficiency is performed on a simple workflow engine developed by the authors. the result is then compared to the existing algorithms including HEFT, GA, PSO, and PSO-SA. the result shows that the proposed GA-PSO algorithm has a good potential to give the minimum cost when the execution time is restricted.

Crowdsourcing emerging as a distributed problem-solving model can dispatch tasks to a large number of human workers. the workers' human intelligence can be utilized to execute tasks which cannot be efficiently performed by computer-based systems. A crowdsourcing environment supports various data processing tasks, for example, data collection, data annotation, data validation, data classification, and natural language processing. In particular, the crowdsourcing environment can be applied for big data processing as well. In this paper, we propose Human-Intelligence-as-a-Service (HIaaS) which is a cloud computing service model utilizing human intelligence in a crowdsourcing marketplace to process big data. We also propose an optimization model based on stochastic programming for provisioning human workers in a HIaaS-based marketplace. Numerical studies are performed to evaluate the optimization model. A video rating system handling a big data set is an illustrative example analyzed in the studies. the results show that the model can efficiently reduce the cost to provision workers for processing a big data job.
