    • Enhanced position estimation via node cooperation 

      Sahinoglu, Z.; Gezici, Sinan (IEEE, 2010)
      Two-way time-of-arrival (TW-ToA) is a widely used ranging protocol that can provide the distance between two devices without time synchronization. One drawback of the TW-ToA is poor positioning accuracy in the absence of ...
    • Spatio-temporal analysis of throughput for single-hop CSMA networks 

      Koseoglu, M.; Karasan, E. (Institute of Electrical and Electronics Engineers Inc., 2014)
      Throughput model for non-persistent CSMA networks which was proposed by Kleinrock and Tobagi has been widely used, although it provides a loose lower bound when nodes are distributed in a large area because the analysis ...
    • Throughput modeling of single hop CSMA networks with non-negligible propagation delay 

      Koseoglu, M.; Karasan, E. (IEEE, 2013)
      We analyze the performance of the CSMA protocol under propagation delays that are comparable with packet transmission times. We propose a semi-Markov model for the 2-node CSMA channel. For the 2-node case, the capacity ...
