Improving peer awareness and group synchronization in MobilePeerDroid system: A comparison study for two fuzzy-based systems

In this work, we present a distributed event-based awareness approach for P2P groupware systems. We 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 Number of Failed Tasks (NFT). Then, we use fuzzy-based model to decide Peer Coordition Quality (PCQ).We call the proposed systems: FPCQS1 and FPCQS2. We make a comparison study between FPCQS1 and FPCQS2. From the simulations results, we conclude that with increasing of the NFT, the PCQ is decreased. When AA, GS and SCT are high, the PCQ is high. The proposed systems can choose reliable peers with good peer coordination quality in mobilePeerDroid mobile system. Comparing the complexity, the FPCQS2 is more complex than FPCQS1. However, FPCQS2 considers also the NFT, which makes the system more reliable.
