    • FIJI: Fighting implicit jamming in 802.11 WLANs 

      Broustis, I.; Pelechrinis, K.; Syrivelis, D.; Krishnamurthy, S. V.; Tassiulas, L. (2009)
      The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...

    • A framework for joint network coding and transmission rate control in wireless networks 

      Kim, T. S.; Vural, S.; Broustis, I.; Syrivelis, D.; Krishnamurthy, S. V.; La Porta, T. F. (2010)
      Network coding has been proposed as a technique that can potentially increase the transport capacity of a wireless network via processing and mixing of data packets at intermediate routers. However, most previous studies ...

    • Handling asymmetry in gain in directional antenna equipped ad hoc networks 

      Jakllari, G.; Broustis, I.; Korakis, T.; Krishnamurthy, S. V.; Tassiulas, L. (2005)
      The deployment of traditional higher layer protocols (especially the IEEE 802.11 MAC protocol at the MAC layer) with directional antennae could lead to problems from an increased number of collisions; this effect is primarily ...

    • Lightweight jammer localization in wireless networks: System design and implementation 

      Pelechrinis, K.; Koutsopoulos, I.; Broustis, I.; Krishnamurthy, S. V. (2009)
      Jamming attacks have become prevalent during the last few years, due to the shared nature and the open access to the wireless medium. Finding the location of a jamming device is of great importance for restoring normal ...

    • Quantifying the overhead due to routing probes in multi-rate WMNs 

      Broustis, I.; Pelechrinis, K.; Syrivelis, D.; Krishnamurthy, S. V.; Tassiulas, L. (2010)
      The selection of high-throughput routes is a key element towards improving the performance of wireless multihop networks. While several routing metrics have been proposed in the literature, it has been shown that link-quality ...

    • Realizing the Benefits of Wireless Network Coding in Multirate Settings 

      Kim, T. S.; Broustis, I.; Vural, S.; Syrivelis, D.; Singh, S.; Krishnamurthy, S. V.; La Porta, T. F. (2013)
      Network coding has been proposed as a technique that can potentially increase the transport capacity of a wireless network via mixing data packets at intermediate routers. However, most previous studies either assume a ...

    • A software framework for alleviating the effects of MAC-aware jamming attacks in wireless access networks 

      Broustis, I.; Pelechrinis, K.; Syrivelis, D.; Krishnamurthy, S. V.; Tassiulas, L. (2011)
      The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...
