  • a morphogenetic and evolutionary approach to regulating wireless access points for energy efficient and reliable connection services
    Congress on Evolutionary Computation, 2015
    Co-Authors: Kei Ohnishi, Kazuya Tsukamoto, Shigeru Kashihara
    Abstract:

    We propose a method for regulating wireless access points (APs) that is based on mechanisms of Biological Development and evolution. The purpose of the proposed regulation is to simultaneously achieve power savings in the APs and achieve reliable connection services through the APs better, which is shown to be a trade-off relationship in this study. The regulation target is the cycle time at which each AP enters the power-off state, which is referred to as the sleep cycle time. Biological Development mechanisms form bodies of a variety of shapes using different genomes as design information, and these genomes are modified evolutionarily. Similarly, in the present study, a method inspired by Biological Development forms a variety of the sleep cycle times of APs, and an evolutionary method modifies the parameter values of the method inspired by the Biological Development in order to obtain better configurations of the APs. In addition, the regulation method is able to configure APs in a distributed manner without knowing global information; the total number of APs, their locations, or their identifiers, which is actually suitable for the situation assumed in the present study, in which APs are established and removed freely by their owners and AP users freely appear. Simulation results show that the proposed method is capable of exploring the tradeoff relationship between the amount of consumed power of the APs and the reliability of connection services in terms of momentary achievement by regulating APs, but yields highly varying regulation results along time.

  • SASO Workshops - Self-configuration of Wireless Access Points Based on Mechanisms of Biological Development and Evolution
    2010 Fourth IEEE International Conference on Self-Adaptive and Self-Organizing Systems Workshop, 2010
    Co-Authors: Kei Ohnishi, Kazuya Tsukamoto, Shigeru Kashihara
    Abstract:

    We propose a method for self-configuration of wireless access points (APs) that is inspired by mechanisms of Biological Development and evolution. The purpose of the proposed configuration is to simultaneously achieve power savings in the APs and achieve reliable connection services through the APs. The configuration target is the cycle time at which each AP enters the power-off state, which is referred to as the sleep cycle time. Biological Development mechanisms form bodies of a variety of shapes using different genomes as design information, and these genomes are modified evolutionarily.

Simulation results suggest that the proposed method is able to achieve power savings and reliable connection services under several assumptions.

  • ArtsIT - Pattern Formation in Networks Inspired by Biological Development
    Lecture Notes of the Institute for Computer Sciences Social Informatics and Telecommunications Engineering, 2010
    Co-Authors: Kei Ohnishi, Kaori Yoshida, Mario Köppen
    Abstract:

    We present a system for pattern formation in networks that is inspired by Biological Development. The system hierarchically forms a specific pattern in a rough-to-detail manner as seen in Biological Development. We apply the system to generating gray-scaled images. In this application, a network topology is first generated from a given original image in which pixels correspond to network nodes and the nodes are linked to one another in a certain way, and then the system is run in the generated network. The pattern formed by the system within the network is a distribution of brightness of pixels which are equal to nodes. The system is shown to create a variety of images which are influenced by the structure in the original image in a rough-to-detail manner. This feature would be useful for designing patterns under some structural constraints.

  • socioemotional personality and Biological Development illustrations from a multilevel Developmental psychopathology perspective on child maltreatment
    Annual Review of Psychology, 2016
    Co-Authors: Dante Cicchetti
    Abstract:

    Developmental theories can be affirmed, challenged, and augmented by incorporating knowledge about atypical ontogenesis. Investigations of the Biological, socioemotional, and personality Development in individuals with high-risk conditions and psychopathological disorders can provide an entree into the study of system organization, disorganization, and reorganization. This article examines child maltreatment to illustrate the benefit that can be derived from the study of individuals subjected to nonnormative caregiving experiences. Relative to an average expectable environment, which consists of a species-specific range of environmental conditions that support adaptive Development among genetically normal individuals, maltreating families fail to provide many of the experiences that are required for normal Development. Principles gleaned from the field of Developmental psychopathology provide a framework for understanding multilevel functioning in normality and pathology. Knowledge of normative developmen...

Principles gleaned from the field of Developmental psychopathology provide a framework for understanding multilevel functioning in normality and pathology. Knowledge of normative Developmental processes provides the impetus to design and implement randomized control trial (RCT) interventions that can promote resilient functioning in maltreated children.
