Author:Mamushiane, Lusani; Mwangama, J; Lysko, Albert ADate:Nov 2018Software Defined Networking (SDN) presents a paradigm shift in network management and configuration. The idea of having an externalized control plane opens many unanswered questions regarding scalability, fault tolerance and performance of ...Read more
Author:Olukanmi, P; Nelwamondo, Fulufhelo V; Marwala, TDate:Aug 2020This paper introduces a hybridization of the k-means and k-medoids paradigms. The new algorithms is named HP (hybrid partitioning) algorithm. Specifically, we improve on a recently developed scalable version of k-means (k-means-lite), by ...Read more
Author:Mamushiane, Lusani; Mwangama, J; Lysko, Albert ADate:Sep 2018Software Defined Networking (SDN) has emerged as a potential solution to the ICT inequality challenge in emerging markets. This technology promises to revolutionize the telecommunications industry by introducing decoupled architectures to ...Read more
Author:Olukanmi, PO; Nelwamondo, Fulufhelo V; Marwala, TDate:Jan 2019The Partitioning Around Medoids (PAM) clustering algorithm is well-known for its robustness and accuracy, but it is computationally expensive. This paper proposes a fast and accurate version, named PAM-lite. Like CLARA which also addresses ...Read more
Author:Olukanmi, PO; Nelwamondo, Fulufhelo V; Marwala, TDate:Jan 2019Using benchmark datasets, we study the performances of three efficient clustering algorithms which find cluster centers using a fixed number of random samples. The algorithms are also compared with two other (well-known) algorithms, namely ...Read more
