Introduction: One of notable initiatives in improving the academic educationis to use the abilities of students to learn together in a new and effective system of peer learning. In this regard, Education Development Center in Shiraz university of Medical Sciences proceed to implementation and study of the curriculum and teaching methods course in the form of peer learning for college students o...

Collaborative applications like video/audio conferencing, IP telephony, file sharing, collaborative work spaces, and multi-user games, having varied security requirements, require a secure and reliable group communication system to provide co-ordination among the processes. Peer to peer computing allows users to interact with each other and find and share resources without requiring a centraliz...

Peer-to-peer (P2P) streaming has been widely deployed over the Internet. A streaming system usually has multiple channels, and peers may form multiple groups for content distribution. In this paper, we propose a distributed overlay framework (called SMesh) for dynamic groups where users may frequently hop from one group to another while the total pool of users remain stable. SMesh first builds ...

In this paper, we investigate the formation of peer-to-peer (P2P) networks with rational participating agents (active peers). In the absence of a central planner, peers choose their own utility-maximizing strategies for coalition and peer formation. P2P networks evolve dynamically through the activities of interactions among individual nodes and group units. We propose a framework for multileve...

The social behavior of peers in peer-to-peer network can be inferred from the observable factors of the system and its components as it is created, lives and evolves. Following a social metaphor, it should be possible to use the observation of these behaviors to organize the network of peers for purposes as various as improving the retrieval performance, efficiently managing storage, improving ...

Peer-to-peer (P2P) energy trading is emerging as a new mechanism for settling the exchange of between renewable generators and consumers. P2P provides local balancing when it facilitated through distributed ledgers (‘blockchains’). Energy communities across Europe have uncovered potential this technology are currently running pilots to test its applicability in trading. The aim paper assess, us...

Peer to peer collaborative groups are becoming increasingly popular for collaborative applications like video/audio conferencing, IP telephony, file sharing, collaborative work spaces, and multi-user games. The decentralized nature of these groups gives rise to the need of a secure group layer which integrates authentication, admission control, authorization, access control and key management. ...
