Selection of Reliable Best Peer in a Group of Peers by Using Correlation Coefficients and ns-3 Simulator

In P2P systems, especially in mobile P2P, it is necessary to consider the mobility tolerance of nodes and the instability of the network. The goal of this research is to develop a system for selecting reliable and best peers in a P2P communication environment. Previous research has focused on improving the reliability of peers and evaluating the reliability of the network as a whole. In this study, we focused on the reliability evaluation of each peer by using correlation coefficients and ns-3 simulator. Foe evaluation, we consider three parameters: delay time, packet loss and throughput. The simulation results show that the proposed systems can choose the best reliable peers.
