In this paper, we present the GD-calculus witch is an elementary functional distributed agent language with a new approach of messages communication between agents in a distributed environment. This strategy is based on a static analysis which allows determining the parts of a message that must be transmitted. The agents we consider have a functional(More)
Amazon Ec2 service offers two diverse instance purchasing options. Users can either run instances by using on-demand plan and pay only for the incurred instance-hours, or by renting instances for a long period, while taking advantage of significant reductions (up to 60%). One of the major problems facing these users is cost management. How to dynamically(More)
In this paper, we propose the assignment problem of resources humans’ methodology by using the multiple knapsack approach to formulate the studied problem, and solve it by using the genetic algorithm for obtaining the optimal assignment of the new qualified employees that ensures the maximization the productivity by introducing constraints corresponding to(More)
The aim of this work is to present a meta-heuristically approach of the spatial assignment problem of human resources in multi-sites enterprise. Usually, this problem consists to move employees from one site to another based on one or more criteria. Our goal in this new approach is to improve the quality of service and performance of all sites with(More)
Protecting and auditing data is not an easy task, especially when it comes to cloud storage. As such, it is essential to design an efficient data auditing scheme along with a recovery process while controlling the cloud fees, in the literature, many works has been devoted to cloud storage security, but the majority did not consider the cloud fees into(More)
We present a new strategy of messages communication in a Multi Agent Distributed Data Mining. This strategy is based on static analysis and mobile agent. The static analysis compiles all messages “send(A,m) to send(A,m,L), where L is the necessary portion of message which will be sent to distant site. In the case where the number of messages “send(A,m,L)”(More)
