Abstract

Purpose

Software-define vehicular networks (SDVN) assure the direct programmability for controlling the vehicles with improved accuracy and flexibility. In this research, the resource allocation strategy is focused on which the seek-and-destroy algorithm is implemented in the controller in such a way that an effective allocation of the resources is done based on the multi-objective function.

Design/methodology/approach

The purpose of this study is focuses on the resource allocation algorithm for the SDVN with the security analysis to analyse the effect of the attacks in the network. The genuine nodes in the network are granted access to the communication in the network, for which the factors such as trust, throughput, delay and packet delivery ratio are used and the algorithm used is Seek-and-Destroy optimization. Moreover, the optimal resource allocation is done using the same optimization in such a way that the network lifetime is extended.

Findings

The security analysis is undergoing in the research using the simulation of the attackers such as selective forwarding attacks, replay attacks, Sybil attacks and wormhole attacks that reveal that the replay attacks and the Sybil attacks are dangerous attacks and in future, there is a requirement for the security model, which ensures the protection against these attacks such that the network lifetime is extended for a prolonged communication. The achievement of the proposed method in the absence of the attacks is 84.8513% for the remaining nodal energy, 95.0535% for packet delivery ratio (PDR), 279.258 ms for transmission delay and 28.9572 kbps for throughput.

Originality/value

The seek-and-destroy algorithm is one of the swarm intelligence-based optimization designed based on the characteristics of the scroungers and defenders, which is completely novel in the area of optimizations. The diversification and intensification of the algorithm are perfectly balanced, leading to good convergence rates.

Abstract

Purpose

This paper aims to examine the mediating role of brand satisfaction and brand trust in brand equity antecedents and outcomes through an empirical investigation of brand equity elements.

Design/methodology/approach

A survey was conducted in Pune and Mumbai, two prominent cities of India. A structured questionnaire focussed on garnering responses on measuring brand equity antecedents and outcomes was circulated to the cell phone users. The questionnaire aimed to assess the role of two additional variables, namely, brand satisfaction and brand trust, in the existing and the conceptual model of brand equity (Keller, 2001). Based on the data analysis, a structural equations path and the mediating model were developed.

Findings

The findings of this study show that the new brand equity model is highly relevant in predicting brand equity as compared to the existing brand equity model (Keller, 2001). The brand equity mediation model clearly elucidates the role of brand trust and brand satisfaction.

Research limitations/implications

With reference to a theoretical contribution, the study broadens the existing hypothetical model of brand equity. The findings of this research provide a strategic and analytical model for brand managers to build brand relationships among their consumers.

Originality/value

The present study challenges the existing model of brand equity (Keller, 2001) and further makes an effort to fill in the gaps in the existing theoretical model of brand equity.

Propósito

Este documento tiene como objetivo examinar el papel mediador de la satisfacción con la marca y la confianza con la marca en los antecedentes y resultados de la equidad de marca a través de una investigación empírica de los elementos de equidad de marca.

Diseño/metodología/enfoque

Se realizó una encuesta en Pune y Mumbai, dos ciudades prominentes de la India. Se distribuyó a los usuarios de teléfonos móviles un cuestionario estructurado centrado en obtener respuestas para medir los antecedentes y resultados del valor de marca. El objetivo del cuestionario era recoger información para evaluar el papel de dos variables adicionales, la satisfacción con la marca y la confianza en la marca en el modelo existente y conceptual del valor de marca (Keller, 2001). El análisis de datos se llevó a cabo a través de la metodología de ecuaciones estructurales y modelo de mediación.

Hallazgos

Los hallazgos de este estudio muestran que el nuevo modelo de equidad de marca es muy relevante para predecir el valor de marca en comparación con el modelo de marca existente (Keller, 2001). El modelo de mediación de la equidad de marca aclara el rol de la confianza y la satisfacción con la marca.

Limitaciones/implicaciones

En relación a la contribución teórica, el estudio amplía el modelo existente de valor de marca. Los resultados de esta investigación proporcionan un modelo estratégico y analítico para que los gerentes creen relaciones de marca entre sus consumidores.

Originalidad/valor

El presente estudio desafía el modelo existente de equidad de marca (Keller, 2001) y además hace un esfuerzo por llenar los vacíos en el modelo teórico existente de equidad de marca.

Palabras clave

Equidad de marca, Satisfacción con la marca, Confianza en la marca, Análisis de ecuaciones estructurales, Análisis de mediación
