      The IBM RS/6000 SP is one of the most successful commercially available multicomputers. SP owes its success partially to the scalable, high bandwidth, low latency network. This paper describes the architecture of Switch2 ...
    • Adaptive schemes for location update generation in execution location-dependent continuous queries 

      Lam, Kam-Yiu; Ulusoy, Ö. (Elsevier Inc., 2006-04)
      An important feature that is expected to be owned by today's mobile computing systems is the ability of processing location-dependent continuous queries on moving objects. The result of a location-dependent query depends ...
    • Adaptive source routing in multistage interconnection networks 

      Aydogan, Y.; Stunkel, C. B.; Aykanat, C.; Abali, B. (IEEE, Los Alamitos, CA, United States, 1996)
      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 ...
    • Adaptive time-to-live strategies for query result caching in web search engines 

      Alıcı, Sadiye; Altıngövde, I. Ş.; Rıfat, Özcan; Cambazoğlu, B. Barla; Ulusoy, Özgür (2012)
      An important research problem that has recently started to receive attention is the freshness issue in search engine result caches. In the current techniques in literature, the cached search result pages are associated ...
    • An adaptive, energy-aware and distributed fault-tolerant topology-control algorithm for heterogeneous wireless sensor networks 

      Deniz, F.; Bagci, H.; Korpeoglu, I.; Yazıcı A. (Elsevier BV, 2016)
      This paper introduces an adaptive, energy-aware and distributed fault-tolerant topology-control algorithm, namely the Adaptive Disjoint Path Vector (ADPV) algorithm, for heterogeneous wireless sensor networks. In this ...
