In this paper we cast DRM in a setting that allows us to model a number of current approaches as games. The DRM game is partitioned into two subgames, one that considers the game associated with content acquisition, and a second that considers how a consumer uses the content, along with a vendor's response to this usage. Examples are provided in order to(More)
—The routing problem in Wireless Mesh Networks is concerned with finding " good " source-destination paths. It generally faces multiple objectives to be optimized, such as i) path capacity, which accounts for the bits per second that can be sent along the path connecting the source to the destination node, and ii) end-to-end delay. This paper presents the(More)
—We present a multi-objective optimization approach for joint throughput optimization and traffic engineering, where the routing request of traffic arrives one-by-one. We provide an Integer Linear Program (ILP) that simultaneously i) maximizes the aggregate throughput, ii) minimizes the resource consumption, and iii) minimizes the maximum link utilization.(More)
We devise a scalable and provably-secure protocol for fully-anonymous broadcast in large-scale networks. Similar to the dining cryptographers networks (DC-NETS), our algorithm uses secure multi-party computation (MPC) to ensure anonymity. However, we address the weaknesses of DC-NETS, which are poor scalability and vulnerability to jamming attacks. When(More)
In this paper, we present a linear programming formulation for the throughput optimization problem in wireless networks that support multi-packet reception (MPR) capability. The formulation takes into account the use of both directional and omni-directional antennas as well as the use of multiple transmitter interfaces per node. The joint routing and(More)
We address the problem of privacy in publish-subscribe(pub-sub) systems that typically expose some form of published content and subscriber interest, at least to the infrastructure responsible for subscription matching and content delivery. In our recent work, we proposed P3S, a pub-sub middleware designed to protect the privacy of subscriber interest and(More)
