Towards an Optimized Scheme for Mobile Subscribers Based on Cloud Computing

摘要

Recently, deploying the publish/subscribe model over Peer-to-Peer networks have been widely used for mobile applications. However, transfer delay and network load remain the challenging issues to consider for mobile subscribers because of their dynamic nature. In this paper, we propose an approach handling mobile subscribers over a Peer-to-Peer architecture, and we illustrate its extension to cloud federation. This extension achieves the realization of a large number of virtual computing clusters, running as into a single cloud organization. Extensive simulation results revealed how our approach can significantly improve transfer delay, and network load compared to previous approaches while applying a wide range of workload parameters, such as frequency of movements, and publication rate.
