Abstract
OSPINA LOPEZ, Juan Pablo and ORTIZ TRIVINO, Jorge Eduardo. Estimation of a Growth Factor to Achieve Scalable ad hoc Networks. Ing. Univ. [online]. 2017, vol.21, n.1, pp.49-70. ISSN 0123-2126. https://doi.org/10.11144/javeriana.iyu21-1.egfa.
Introduction:
this study focuses on determining the conditions that guarantee scalability in a hierarchical architecture based on the resources available in the different layers of the network.
Methods:
a model based on the truncated geometric distribution that allows the characterization of the available resources in an ad hoc network was proposed. From this characterization, the concept of growth factor φ was introduced as a constant value that represents the appropriate relationship from among the available resources in two successive layers of the network to ensure scalability. The ns-3 software was used to develop simulation scenarios that were explored to develop the estimation process of the growth factor φ in the ad hoc networks of two- and three-layer hierarchical architectures.
Results:
The results showed that the growth of resources among the layers in an ad hoc network can be expressed in a linear model. Moreover, a relation was found between the estimated value of j and the golden ratio as a way to inspire the design of artificial systems based on attributes that can be found in nature.
Keywords : ad hoc networks; scalability; stochastic model; Golden Ratio.
