Abstract

The topological design of a computer communication network assigns the links and link capacities for connecting network nodes within several constraints, with a goal to achieve a specified performance at a minimal cost. A reasonable approach is to generate a potential network topology. This paper presents a spanning tree based method for systematic numbering of nodes in any communication network. When the nodes are numbered in a systematic manner the potential network topology generated will have lesser amount of perturbation before an acceptable network is found.

Abstract

Background: Gait uniquely distinguishes the persons by using their physiological and psychological state. For this reason, human gait recognition at a distance recently gained wider interest from research community. In recent days, the concept of fusion based biometric systems has attracted many researchers and it is proved that gait can be valuable solution when all other biometric sources failed. However gait is still open research area. Method: The review explains the observations with the help of available data and scientific arguments of the experts in their documented works are also taken for our study. Findings: This paper provides a comprehensive survey of current developments on gait recognition approaches and emphasizes on three major phases involved in gait recognition system, namely representation, dimensionality reduction and classification. We also discuss in detail the pragmatic conditions of gait and efficient utilization of standard datasets in order to use gait recognition systems in masses. Also we highlighted the prominent guidelines to internal and external gait challenges. Further we provide the motivations for fusion of physiological and psychological biometric sources to accomplish practical scenarios. Application/Improvement: The study concludes that all previous attempts are restricted to only few external gait variations and evaluated on limited data set. However, there is no single attempt which addresses most of the external gait variations. Hence there is a scope for further exploration and evaluation.

Abstract

Background: One of the key considerations in the topological design of a network is the fault tolerance and survivability of the network topology. A deterministic measure for fault tolerance proposed by computer scientist and researchers is the k-node connectivity number of the network graph. Fault may happen at the physical level or at the software level. Method: A few heuristics and methods are proposed in the literature for the design of k-node connected network topological structures. The methods are analyzed on the parameters such as link optimality, computational efforts, repeated searching of nodes, adopting node numbering techniques, mathematical modelling, generality of the methods etc. Findings: This article portrays the comprehensive study and investigation of existing works and current developments on the design of k-node connected topological design of computer communication network structures, applicable for both wired and wireless network structures. This paper also highlights on the various design methods applicable for specific cases and also compares the existing and current methods, for the design parameters considered. Applications/Improvement: The study concludes by stating that the previous methods and strategies are restricted only to a few network design parameters. However there is no single method which addresses most of the issues, hence there is a scope for future exploration design methods.
