Often, they stage their attacks through intermediate “stepping stones” in order to conceal their identity and origin. To distinguish the source of the attack behind the stepping stone(s), it is important to associate the incoming and outgoing flows or connections of a stepping […]
ABSTRACT: Many next-generation applications, (for example, video flows) are likely going to have related minimum data rate requirements in order to ensure satisfactory quality as perceived by end-users. In this project, we develop a system to address the issue of maximizing the aggregate utility of traffic flows in a multi-hop wireless network, with constrains imposed both […]
ABSTRACT: Community Question Answering (CQA) services have gained popularity over the past years. It not just enables community members to post and answer the question but also enables general clients to seek for data from a comprehensive set of well-answered question.

ABSTRACT: Firewalls have been widely deployed on the Internet for securing private networks. A firewall checks every incoming or outgoing packet to choose whether to accept or discard the packet based on its strategy. Optimizing firewall policies is crucial for enhancing network performance. Prior work on firewall optimization focuses on either intra-firewall or inter-firewall optimization […]
ABSTRACT: Peer to peer (P2P) databases is getting to be prevalent on the Internet for distribution and sharing of documents, applications and other digital media. The issue of answering large-scale ad hoc analysis queries, for example, aggregation queries, on these databases possess unique challenges. Exact solutions can be time-consuming and difficult to implement, given the distributed and […]
ABSTRACT: Websites that give content creation and sharing highlights have turned out to be quite popular recently. These sites enable clients to categorize and browse content utilizing “tags” or free-text keyword topics. Since clients contribute and tag social media content across a variety of social web platforms, creating new knowledge from distributed tag information has […]
ABSTRACT: A search-as-you-type system computes answers on-the-fly as a client type in a keyword query character by character. We study how to support search-as-you-type on data residing in a relational DBMS. We focus on how to support this kind of search utilizing the native database language, SQL. A principle challenge is the means by which to […]
ABSTRACT: As cloud computing turns out to be more and more popular, understanding the economics aspects of cloud computing turns out to be critically important. To maximize the profit, a service provider ought to understand both service charges and business costs, and how they are determined by the attributes of the applications and the configuration […]
