This paper presents a performance evaluation of the mobile agent paradigm in comparison to the client/server paradigm. This evaluation has been conducted on top of the Java environment, using respectively RMI, the Aglets mobile agents platform and a mobile agents prototype that we implemented. The measurements give the cost of the basic mechanisms involved(More)
Within the class of non-homogeneous Poisson process (NHPP) models and as a result of the simplicity of the mathematical computations of the Power Law Process (PLP) model and the attractive physical explanation of its parameters, this model has found considerable attention in repairable systems literature. In this article, we conduct the investigation of new(More)
Software reliability models (SRMs) are very important for estimating and predicting software reliability in the testing/debugging phase. The contributions of this paper are as follows. First, a historical review of the Gompertz SRM is given. Based on several software failure data, the parameters of the Gompertz software reliability model are estimated using(More)

Nowadays, grid applications and Web applications introduce significant high availability and scalability challenges to cluster database servers. In this paper, we describe a connection failover mechanism toward building a highly availably infrastructure that is resistant to partial failure. While available solutions concentrate on client transparency, in(More)
