In this paper, we present a social network based network communication architecture, Davis Social Links (DSL). DSL uses the trust and relationships inherent to human social networks to provide an enhanced communication architecture for future Internet designs. We begin with a conceptual discussion of how future network architectures can leverage social(More)
— Many tasks require multiple sensing capabilities; in Wireless Sensor Networks (WSN), it is expensive to deploy a homogeneous network wherein every sensor has the same functionality. Instead, it is economical to deploy a heterogeneous network wherein sensors differ in their capabilities; in such a network, efficient data querying is essential. We propose a(More)
Online Social Networks (OSN) are experiencing an explosive growth rate and are becoming an increasingly important part of people's lives. There is an increasing desire to aid online users in identifying potential friends, interesting groups, and compelling products to users. These networks have offered researchers almost total access to large corpora of(More)
Gene therapy offers significant advantages to the field of oncology with the addition of specifically and uniquely engineered mechanisms of halting malignant proliferation through cytotoxicity or reproductive arrest. To confer a true benefit to the therapeutic ratio (the relative toxicity to tumor compared to normal tissue) a vector or the transgene it(More)
—When the Internet was conceived, its fundamental operation was envisioned to be point-to-point communication allowing anybody to talk directly to anybody. This paper introduces a clean-slate approach to redesigning the Internet, entitled Davis Social Links (DSL). Instead of directly connecting the source and sink, DSL routes the message (or request to(More)
— In large Wireless Sensor Networks (WSNs), each hop might incur varying delays due to medium access contention, transmission and computation delays. Fast and efficient query responses are essential to network performance and maintenance. To save energy in battery-powered sensors, it is desirable that data be aggregated or compressed along the way toward(More)
—As wireless motes are battery powered, many listen-sleep Medium Access Control (MAC) protocols have been proposed to reduce energy consumption. Security issues related to the design of these protocols have, however, largely been ignored. In this paper, we present a novel attack (the synchronization attack) on listen-sleep MAC protocols. This attack can(More)
