A Performance Evaluation Framework for Mobile P2P Overlays under Churn
نویسندگان
چکیده
With the popular use of the mobile intelligence equipment, including smartphones and mobile tablets, mobile peer-to-peer (P2P) networks have become increasingly important. In recent years some mobile P2P overlays have been proposed. We propose a three-dimension evaluation framework for mobile P2P overlays under churn. Three P2P overlays, named as GIA, M-GIA, and KCCO(k-Clique Community Overlay), are chosen to be evaluated according to our framework. Two kinds of churn models are used to compare the performance of three P2P overlays for achieving more comprehensive results. Simulation results show that our framework could be used for performance evaluation of various overlays under different conditions, especially under high churn. With this framework, KCCO shows better suitability for mobile networks, because it gets much higher query success rate than other two overlays, and takes less average query delay than other overlays in most cases. Key-Words: performance evaluation, mobile peer-to-peer overlay, churn, k-clique, query success rate, average query delay.

متن کاملMulti-factors oriented study of P2P Churn
The dynamics of peers, namely Churn, is an inherent property of peer-to-peer (P2P) systems and is critical to their design and evaluation. Although every excellent P2P protocol has some solution to this issue, studies on Churn are still seldom. This paper studies various factors related to Churn, and uses them to analyze and evaluate P2P protocols. Prior researches on Churn are all based on the...

متن کاملEvaluation of hierarchical DHTs to mitigate churn effects in mobile networks
Existing flat peer-to-peer (P2P) systems based on distributed hash tables (DHTs) perform unsatisfactorily under churn due to their non-hierarchical topology. These flat DHTs (FDHTs) experience low lookup success ratio, high lookup latency and high bandwidth usage as a consequence of the presence of churn. With this, we explore the use of hierarchical DHT (HDHT), specifically the superpeer desig...
