Peer-to-peer (P2P) streaming has recently received much research attention, with successful commercial systems showing its viability in the Internet. Despite the remarkable popularity in real-world systems, the fundamental properties and limitations are not yet well understood from a theoretical...

Many peer-to-peer overlay operations are inherently parallel and this parallelism can be exploited by using multi-destination multicast routing, resulting in significant message reduction in the underlying network. We propose criteria for assessing when multicast routing can effectively be used,...

Content distribution is the primaryfunction of the Internet today.Technologies like multicast andpeer-to-peer networks hold the potentialto serve content to large populations ina scalable manner. While multicastprovides an efficient transportmechanism for one-to-many andmany-to-many delivery of...

Landmark-based architecture has been commonly adopted in the networking community as a mechanism to measure and characterize a host's location on the Internet. In most existing landmark based approaches, end hosts use the distance measurements to a common, fixed set of landmarks to derive an...

This paper provides an overview of internet file sharing networks and explores the relationship between technological, economic, and legal aspects of file sharing. I chronicle the evolution of content sharing technology since the 1990s, and examine the role of network architecture for a...

In this paper we use mechanism design approach to find the optimal file-sharing mechanism in a peer-to-peer network. This mechanism improves upon existing incentive schemes. In particular, we show that peer-approved scheme is never optimal and service-quality scheme is optimal only under certain...

The NewTies project is implementing a simulation in which societies of agents are expected to de-velop autonomously as a result of individual, population and social learning. These societies are expected to be able to solve environmental challenges by acting collectively. The challenges are...

Computer networks and distributed systems in general may be regarded as communities where the individual components, be they entire systems, application software or users, interact in a shared environment. Such communities dynamically evolve with components or nodes joning and leaving the...

Sustainability issues in Asian metropolitan centers have attracted considerable attention recently, but most studies have focused primarily on providing a comprehensive comparison of economic, social, and environmental indicators in various cities. The interaction between nature and cities...
