    • Adaptive source routing in multistage interconnection networks 

      Aydoğan, Yücel; Stunkel, C. B.; Aykanat, Cevdet; Abali, B. (IEEE, 1996-04)
      We describe the adaptive source routing (ASR) method which is a first attempt to combine adaptive routing and source routing methods. In ASR, the adaptivity of each packet is determined at the source processor. Every packet ...

    • A branch-and-cut algorithm for the alternative fuel refueling station location problem with routing 

      Arslan, O.; Karaşan, Oya Ekin; Mahjoub, A. R.; Yaman, Hande (INFORMS, 2019)
      Because of the limited range of alternative fuel vehicles (AFVs) and the sparsity of the available alternative refueling stations (AFSs), AFV drivers cooperatively deviate from their paths to refuel. This deviation is ...

    • Constructing energy efficient bluetooth scatternets for wireless sensor networks 

      Saginbekov, Sain (Bilkent University, 2004)
      The improvements in the area of wireless communication and micro-sensor technology have made the deployment of thousands, even millions, of low cost and low power sensor nodes in a region of interest a reality. After ...

    • The cost and risk impacts of rerouting railroad shipments of hazardous materials 

      Glickman, T. S.; Erkut, E.; Zschocke, M. S. (Elsevier, 2007)
      Rail shipments of hazardous materials expose the population near the routes to the possibility of an accident resulting in a spill. Rail routes are determined by economic concerns such as route length and the revenue ...

    • Designing a road network for hazardous materials shipments 

      Erkut, E.; Alp, O. (Elsevier, 2007)
      We consider the problem of designating hazardous materials routes in and through a major population center. Initially, we restrict our attention to a minimally connected network (a tree) where we can predict accurately the ...

    • Distributed power-source-aware routing in wireless sensor networks 

      Tekkalmaz, M.; Korpeoglu, I. (Springer New York LLC, 2016)
      Although many applications use battery-powered sensor nodes, in some applications battery- and mains-powered nodes coexist. In this paper, we present a distributed algorithm that considers using mains-powered devices to ...

    • Fly-path: Traffic-based multi-hop routing approach for hybrid wireless data centers 

      Mergenci, Cem; Körpeoğlu, İbrahim (Elsevier BV, 2021-03-15)
      High data transfer rates achieved by 802.11ad at 60 GHz ISM band enables use of wireless communication in data centers. In this paper, we investigate the possibility of offloading traffic from wired to wireless network in ...

    • Green location and routing problems with conventional vehicles and drones 

      Dükkancı, Okan (Bilkent University, 2019-05)
      Green Location and Routing Problems extend the network design problems that consider location and routing decisions by explicitly accounting environmental impacts such as CO2 emissions caused by fuel or energy consumption ...

    • GridRoute : a multi-layered grid based routing protocol for delay tolerant mobile networks 

      Köksal, Emin Yiğit (Bilkent University, 2012)
      This work proposes a new routing protocol for delay-tolerant mobile networks (DTMNs) called GridRoute. The proposed protocol can be adopted considering network requirements such as low message delay or low resource usage. ...
