Peer-to-peer (P2P) systems are becoming increasingly popular and complex, serving millions of users today. However, the design of current unstructured P2P systems does not take full advantage of rich locality properties present in P2P system workloads, thus possibly resulting in inefficient searches or poor system scalability. In this paper, we propose a novel locality-aware P2P system architec...

Peer-to-peer information systems have gained prominence of late with applications such as file sharing systems and grid computing. However, the information retrieval component of these systems is still limited because traditional techniques for searching and ranking are not directly applicable. This work compares search in peer-to-peer information systems to that in metasearch engines, and desc...

In this paper a trilateral Multi-Master-Single-Slave-System with control authority allocation between two human operators is proposed. The authority coefficient permits to slide the dominant role between the operators. They can simultaneously execute a task in a collaborative way or a trainee might haptically only observe the task, while an expert is in full control. The master devices are conn...

In this paper we present key elements of a peer to peer (P2P) based software architecture for integrated and collaborative product engineering. We argue that distributed and cross-enterprise product lifecycle management can benefit from the availability of decentrally managed product model repositories. We present the overall system architecture of a platform called Peer-to-Peer Product Collabo...
