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...

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...

With the extremely rapid development of the Internet in recent years, emerging peer-to-peer network overlays are meeting the requirements of a more sophisticated communications environment, providing a useful substrate for applications such as scalable file sharing, data storage, large-scale...

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...

Game theoretic modeling involves making assumptions on agents' infinite hierarchies of beliefs. These assumptions are understood to be only approximately satisfied in the actual situation. Thus, the significance of game theoretic predictions depend on robustness properties of the solution...

"In 1968, Hardin argued that all commonly-owned resources would tragically be depleted unless private ownership was granted. There are many case studies which prove Hardin wrong. Common-pool resources have been managed with success. However, this success does not imply (as some believe) that...

This paper is a theoretical analysis of incentive setting via civil litigation, with a focus on incentives for care in activities that may be harmful to others (torts). It makes two main contributions: one directly policy-relevant, one conceptual. In most existing research, litigation is modeled...

This dissertation uses game theoretic models to examine the effects of agent anonymity on markets for goods and for information. In open, anonymous settings, such as the Internet, anonymity is relatively easy to obtain --- oftentimes another email address is sufficient. By becoming anonymous,...

With the world full of situations in which information that is potentially useful to decision-making is dispersed among various individuals, research into how this information can be efficiently shared has been the focus of a large body of research in recent years. Intuitively, it seems that...

In the first section, a firm with two servers must decide how to dynamically route arriving customers and allocate servers to two separate queues. The servers may work together or separately, and we provide insights into how the firm should optimally route customers and assign servers to queues....
