    • Bluetooth or 802.15.4 technologies to optimise lifetime of wireless sensor networks: Numerical comparison under a common framework 

      Buratti, C.; Körpeoğlu, İbrahim; Karasan, Ezhan; Verdone, R. (IEEE, 2008-04)
      This paper aims at comparing through simulations the network lifetime of a wireless sensor network using Bluetooth-enabled or IEEE802.15.4 compliant devices. The evaluation is performed under a common reference framework, ...

    • Distributed and location-based multicast routing algorithms for wireless sensor networks 

      Korpeoglu, I.; Bagci, H. (SpringerOpen, 2009-01)
      Multicast routing protocols in wireless sensor networks are required for sending the same message to multiple different destinations. In this paper, we propose two different distributed algorithms for multicast routing in ...

    • Distributed construction and maintenance of bandwidth and energy efficient bluetooth scatternets 

      Tekkalmaz, M.; Sözer, H.; Korpeoglu, I. (Institute of Electrical and Electronics Engineers, 2006-09)
      Bluetooth networks can be constructed as piconets or scatternets depending on the number of nodes in the network. Although piconet construction is a well-defined process specified in Bluetooth standards, scatternet formation ...

    • First large-scale information retrieval experiments on Turkish texts 

      Can, Fazlı; Koçberber, Seyit; Balcık, Erman; Kaynak, Cihan; Öcalan, H. Çağdaş; Vursavaş, Onur M. (ACM, 2006-08)
      We present the results of the first large-scale Turkish information retrieval experiments performed on a TREC-like test collection. The test bed, which has been created for this study, contains 95.5 million words, 408,305 ...

    • Information retrieval on Turkish texts 

      Can, F.; Kocberber, S.; Balcik, E.; Kaynak, C.; Ocalan, H. C.; Vursavas, O. M. (John Wiley & Sons, Inc., 2008-02)
      In this study, we investigate information retrieval (IR) on Turkish texts using a large-scale test collection that contains 408,305 documents and 72 ad hoc queries. We examine the effects of several stemming options and ...

    • Joint topology design with routing and power control in ad hoc networks 

      Önal, Aydoğan (Bilkent University, 2003)
      We discuss the problem of designing an ad hoc network topology by jointly using power control and routing. A well-designed topology in ad hoc networks provides several advantages: increasing the capacity, decreasing the ...

    • A path-quality-aware peer-to-peer file sharing protocol for mobile ad-hoc networks: Wi-Share 

      Karasabun, Efe; Ertemür, Doğuş; Sarıyıldız, Seyhun; Tekkalmaz, Metin; Körpeoğlu, İbrahim (IEEE, 2009-09)
      Peer-to-peer networks are rather well-studied and currently there are numerous systems based on peer-to-peer principles running on the Internet. On the other hand peer-to-peer networks for mobile ad-hoc networks have ...

    • A peer-to-peer file search and download protocol for wireless ad-hoc networks 

      Sözer, H.; Tekkalmaz, M.; Korpeoglu, I. (Elsevier BV, 2009-01)
      Deployment of traditional peer-to-peer file sharing systems on a wireless ad-hoc network introduces several challenges. Information and workload distribution as well as routing are major problems for members of a wireless ...

    • A performance comparison of zone-based multicast protocols for mobile ad hoc networks 

      Zhang, Y.; Rangnekar, A.; Selçuk, Ali A.; Bicak, A.; Sidhu, D. (IEEE, 2003)
      With the current trend toward ubiquitous computing come wireless devices capable of forming the nodes of mobile ad hoc networks. Such networks typically rely on routing protocols in order to communicate messages from a ...

    • PETAL: a fully distributed location service for wireless ad hoc networks 

      Ilkhechi, A. R.; Korpeoglu, I.; Güdükbay, Uğur; Ulusoy, Özgür (Academic Press, 2017)
      Location service is an essential prerequisite for mobile wireless ad hoc networks (MANETs) in which the underlying routing protocol leverages physical location information of sender and receiver nodes. Fulfillment of this ...

    • A survey on scheduling in IEEE 802.16 mesh mode 

      Kas, M.; Yargicoglu, B.; Korpeoglu, I.; Karasan, E. (Institute of Electrical and Electronics Engineers, 2010)
      IEEE 802.16 standard (also known as WiMAX) defines the wireless broadband network technology which aims to solve the so called last mile problem via providing high bandwidth Internet even to the rural areas for which the ...

    • Topology design and scheduling in STDMA based wireless ad hoc networks 

      Ergin, Sadettin Alp (Bilkent University, 2003)
