    An octopus-inspired intrusion deterrence model in distributed computing system
    (Wydawnictwa AGH, 2016) Olajubu, Emmanuel A.; Akinwale, Abiodun; Ogundoyin, Kazeem Ibraheem
    The study formulated and evaluated a model for effective management of malicious nodes in mobile Ad-hoc network based on Ad-Hoc on- demand distance vector routing protocol. A collaborative injection model called Collaborative Injection Deterrence Model (CIDM) was formulated using stochastic theory. The definition of the model was presented using graph theory. CIDM was simulated using three different scenarios. The three scenarios were then compared using packets delivery ratio (PDR), routing load, throughput and delay as performance metrics. The simulation result showed that CIDM reduce considerably the rate of packets dropped caused by malicious nodes in MANET network. CIDM did not introduce additional load to the network and, yet produce higher throughput. Lastly, the access delay in CIDM is minimal compared with convectional OADV. The study developed a model to mete out a punitive measure to rogue nodes as a form of intrusion deterrence without degrading the overall performance of the network. The well known CRAWDAD dataset was used in the simulation.

    In this paper, a load balancing issue for Cloud Computing based web servers was described. Author made review of the most popular (commercial and noncommercial) Cloud Computing systems. The EUCALYPTUS cloud and its use for parallel processing for web services was presented. The review of three load balancing algorithms (Request Counting, Weighted Traffic Counting and Pending Request Counting) was shown.
