FBPCQS-Fuzzy-Based Peer Coordination Quality Systems for P2P Networks

Abstract

This work presents a distributed event-based awareness approach for P2P groupware systems. The authors present two fuzzy-based systems for improving peer awareness and group synchronization according to four parameters: activity awareness (AA), sustained communication time (SCT), group synchronization (GS), and peer communication cost (PCC). Then, this research uses fuzzy-based model to decide peer coordination quality (PCQ). The authors call the proposed systems: fuzzy-based peer coordination quality (FBPCQ) systems (FBPCQS1 and FBPCQS2). The authors make a comparison study between FBPCQS1 and FBPCQS2. The simulations results conclude that when AA, GS, and SCT are high, the PCQ is high, but with increasing of the PCC, the PCQ is decreased. The proposed systems can choose reliable peers with good peer coordination quality in mobilePeerDroid mobile system. Comparing the complexity, the FBPCQ2 is more complex than FBPCQS1. However, FBPCQS2 considers also the PCC, which makes the system more reliable.
