    • Ad Hoc 802.11b cooperative protocols: performance in a slow fading channel 

      Agarwal, Niraj, 1977-; ChanneGowda, Divya, 1981-; Kannan, Lakshmi Narasimhan, 1984-; Tacca, Marco, 1973-; Fumagalli, Andrea (The University of Texas at Dallas, 2013-05-24)
      This paper investigates the use of cooperative communications in the context of ad hoc IEEE 802.11b to combat radio signal degradations due to slow fading. The performance gain of both an existing cooperative protocol and ...
    • An analytical model with improved accuracy of IEEE 802.11 protocol under unsaturated conditions 

      Vijayasankar, Kumaran, 1984-; Taufique, Azar; Kannan, Lakshmi Narasimhan, 1984-; Tacca, Marco, 1973-; Fumagalli, Andrea (The University of Texas at Dallas, 2013-05-23)
      In this work the authors present an analytical model that - compared to previously published work- more accurately captures the delay of IEEE 802.11 protocol under low, medium, and near-saturation load conditions. A Markov ...
    • Cooperative communications in multihop networking: a case study based on the IEEE 802.11 protocol 

      Kannan, Lakshmi Narasimhan, 1984-; Vijayasankar, Kumaran, 1984-; ChanneGowda, Divya, 1981-; Agarwal, Niraj, 1977-; Fumagalli, Andrea; Tacca, Marco, 1973- (The University of Texas at Dallas, 2013-05-24)
      This paper combines multi-hop networking with single-hop cooperative communications. The solution is built upon the standard IEEE 802.11 protocol operating in the ad hoc mode. A simulation based comparison is carried out ...
    • A cross layer routing metric with wireless cooperative protocols 

      Vijayasankar, Kumaran, 1984-; Kannan, Lakshmi Narasimhan, 1984-; Tacca, Marco, 1973-; Fumagalli, Andrea (The University of Texas at Dallas, 2013-06-18)
      Cooperative link layer protocols are typically used in single hop networks. In such protocols, a special node called the relay node helps deliver frames from a source to a destination. The performance benefits of cooperation ...
    • Hardware Trojans in Wireless Networks 

      Subramani, Kiruba Sankaran (2018-08)
      The area of hardware security has received intense scrutiny in recent years due to outsourcing of semiconductor device manufacturing, use of third party Intellectual Properties (IPs) in the fabricated design, Electronic ...
