Community detection algorithms are widely used to study the structural properties of real-world networks. In this paper, we experimentally evaluate the qualitative performance of several community detection algorithms using large-scale email networks. The email networks were generated from real email traffic and contain both legitimate email (ham) and(More)
Identifying unsolicited email based on their network-level behavior rather than their content have received huge interest. In this study, we investigate the social network properties of large-scale <i>email networks</i> generated from real email traffic to reveal the properties that are indicative of spam as opposed to the expected legitimate behavior. By(More)
In this paper, we study the problem of identifying misbehaving network communications using community detection algorithms. Recently, it was shown that identifying the communications that do not respect community boundaries is a promising approach for network intrusion detection. However, it was also shown that traditional community detection algorithms are(More)
—Passive monitoring of network performance parameters is experiencing a revival due to widespread adoption of virtualization and software-based implementation of network functions. Timestamping is one of the most challenging operations needed for passively monitoring network traffic performance parameters such as latency and jitter. We develop a setup(More)
—Dynamic Adaptive Streaming over HTTP (DASH) constitutes a large fraction of traffic in the mobile Internet. Mobile devices often use video delivery over Wi-Fi, which is a significant energy drain. Dynamic Power Saving Mode (DPSM) is one of the most widely-used approaches for Wi-Fi devices to save power and shorten packet delay. However, DPSM uses a fixed(More)

—One of the widely studied structural properties of social and information networks is their community structure, and a vast variety of community detection algorithms have been proposed in the literature. Expansion of a seed node into a community is one of the most successful methods for local community detection, especially when the global structure of the(More)
Today web portals play an increasingly important role in health care allowing information seekers to learn about diseases and treatments, and to administrate their care. Therefore, it is important that the portals are able to support this process as well as possible. In this paper, we study the search logs of a public Swedish health portal to address the(More)
