ACM Transactions on Internet Technology

In recent years there has been an explosive growth of digital content in the form of news feeds, videos, and original content on online platforms such as blogs and social networks. Indeed, such platforms have been used as a means of sharing and ...

The search neutrality debate questions the ranking methods of search engines. We analyze the issue when content providers offer content for free, but get revenues from advertising. We investigate the noncooperative game among competing content providers ...

Representatives of several Internet service providers (ISPs) have expressed their wish to see a substantial change in the pricing policies of the Internet. In particular, they would like to see content providers (CPs) pay for use of the network, given ...

Nowadays digital services, such as cloud computing and network access services, allow dynamic resource allocation and virtual resource isolation. This trend can create a new paradigm of flexible pricing schemes. A simple pricing scheme is to allocate ...

The goal of this article is to develop a principled understanding of when it is beneficial to bundle technologies or services whose value is heavily dependent on the size of their user base, that is, exhibits positive exernalities. Of interest is how ...

In designing new service plans, network service providers need to understand how consumption of voice or data service will change in response to pricing signals. It is difficult to acquire such information from customer usage data because voice minutes ...

We introduce a private commons model that consists of network providers who serve a fixed primary demand and strategically price to improve their revenues from an additional secondary demand. For general forms of secondary demand, we establish the ...

We study combinatorial auctions for secondary spectrum markets, where short-term communication licenses are sold to wireless nodes. Channels can be assigned to multiple bidders according to interference constraints captured by a conflict graph. We ...

Sponsored search auctions are the main source of revenue for search engines. In such an auction, a set of utility maximizing advertisers competes for a set of ad slots. The assignment of advertisers to slots depends on the bids they submit; these bids ...

Price of anarchy is an oft-used worst-case measure of the inefficiency of noncooperative decentralized architectures. For a noncooperative load-balancing game with two classes of servers and for a finite or infinite number of dispatchers, we show that ...

We develop a formal nondeterministic game model for secure team composition to counter cyber-espionage and to protect organizational secrets against an attacker who tries to sidestep technical security mechanisms by offering a bribe to a project team ...

This article considers cloud service composition from a decision analysis perspective. Traditional QoS-aware composition techniques usually consider the qualities available at the time of the composition because compositions are usually immediately ...

With this article, we give an answer to one of the open problems of mashup development that users may face when operating a model-driven mashup tool, namely the lack of modeling expertise. Although commonly considered simple applications, mashups can ...
