A secure intersection-based routing protocol for data collection in urban vehicular networks

2014

Data routing has gained great intention since the appearance of Vehicular Networks (VANETs). However, in the presence of attackers, reliable and trustworthy operations in such networks become impossible without securing routing protocols. In this paper, we target to study and design a secure routing protocol S-GyTAR for vehicular environments. Several kinds of routing techniques are proposed in the literature and could be classified into topology-based or position-based strategies. Position-based is the most investigated strategy in vehicular networks due to the unique characteristics of such networks. For this reason, this work is based on the well-known intersection-based routing protocol…

Evaluating a bound for MANETs routing protocols performance using graphs with activation windows

2008

In this paper we present an algorithm called STPA (shortest time path algorithm) which aims at providing a comparison tool for the evaluation of a bound for mobile ad hoc networks (MANETs) routing protocols performance. STPA provides an exhaustive evaluation of an ideal routing protocol. Based on the current position and state of the nodes it can determine factors like: how many complete messages get to the destination, which is the smallest amount of time required by a packet to get to the destination, which path followed each packet, and so on. This values would allow a protocol designer to improve or fine tune his proposal. We demonstrate that the complexity of the algorithm is O(sigma2)…

The promotion of a tourist destination by its sensorial perspective definition

2016

In the last years there has been a special attention towards sensory marketing and experiential economy (Hulten, Broweus & Dijk, 2009). Some related contributions (Kim, Ritchie & Tung, 2010; Volo, 2010) in tourism have payed attention to a possible service customization in terms of sensorial stimuli that can be effective for the customers (Scott, Laws & Boksberger, 2010). The literature has recently emphasized the importance of the senses through which to perceive and know an area for a more complete tourist experience (Cherifi, 2015; Liu, Wang, Liu & Deng, 2005). Considering that the brand of a tourist destination expresses its identity and it should represent the synthesis of its promotio…

Memorable tourist experiences versus ordinary tourist experiences analysed through user-generated content

2020

Abstract This study aims to test some previously proposed MTE (memorable tourist experience) scales by using UGC (user-generated content) posted in social media sites, through script theory and thematic analysis. In addition, MTEs and OTEs (ordinary tourist experiences) are compared to identify any significant differences between their dimensions. The results suggest that some dimensions of the MTE scale (hedonism, novelty, meaningfulness, involvement, knowledge and serendipity) are significantly more frequently reported in MTEs than in OTEs, but are not exclusive to MTEs. Despite this, the MTE scale dimensions are able with some accuracy to classify tourist experiences as MTEs or OTEs. Thu…

Insights into online reviews of hotel service attributes: A cross-national study of selected countries in Africa

2018

Online travel reviews are paramount to trip planning because they help consumers’ form images of destinations. Despite ample studies on hotel service attributes, knowledge is scarce regarding culturally nuanced attributes, including security perceptions. This study examines consumers’ perceptions of service attributes and security/safety concerns of hotels in Africa. Data were extracted from three hotel categories (3, 4, and 5-stars), which were based on TripAdvisor rankings from Egypt, Ghana, Kenya, Nigeria, and South Africa. A hybrid analysis revealed that hotel service attributes and security/safety are cardinal evaluation criteria for visitors to Africa. Additionally, our study reveals …

Exploring the links between destination attributes, quality of service experience and loyalty in emerging Mediterranean destinations

2020

Abstract Since the publication of the “Experience Economy” work by Pine and Gilmore in 1999, understanding the increasing complexity of the customer experience within the customer journey in the tourism industry is a priority for researchers and destination management organizations. This study contributes to the extension of the Experience Economy in tourism research by examining the links between tourists' assessment of destination attributes, their perceived quality of the service experience and loyalty, in seven emerging Mediterranean destinations. To date, little research has explored the aforementioned aspects, even though the Mediterranean region is the leading tourism destination in …

A Scatter Search Algorithm for the Split Delivery Vehicle Routing Problem

2008

In this chapter we present a metaheuristic procedure constructed for the special case of the Vehicle Routing Problem in which the demands of clients can be split, i.e., any client can be serviced by more than one vehicle. The proposed algorithm, based on the scatter search methodology, produces a feasible solution using the minimum number of vehicles. The quality of the obtained results is comparable to the best results known up to date on a set of instances previously published in the literature.

Efficient Local Search Limitation Strategies for Vehicle Routing Problems

2008

In this paper we examine five different strategies for limiting the local search neighborhoods in the context of vehicle routing problems. The vehicle routing problem deals with the assignment of a set of transportation orders to a fleet of vehicles, and the sequencing of stops for each vehicle to minimize transportation costs. The examined strategies are applied to three standard neighborhoods and implemented in a recently suggested powerful memetic algorithm. Experimental results on 26 well-known benchmark problems indicate significant speedups of almost 80% without worsening the solution quality. On the contrary, in 12 cases new best solutions were obtained.

Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily

2018

L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…

Settore M-GGR/02 - Geografia Economico-PoliticaThe current debate about the Italian territorial reorganization makes again fundamental the concept of «territory». This paper aims to reflect on some important dynamics that concern the idea of territory. More in particular I explore in which form it can be (re)semantised through some tourism representations and narrations able to create specific ways of interaction. By taking into account the case study of the Lonely Planet 2017 digital tourist guidebook dedicated to Sicily that splits (and reorganizes) the island in smaller «regions» it is possible to reflect on a complex space dynamic able to redefine the same idea of territory. Indeed the tourist guidebook uses both texts and geographical maps to propose an anthology of homogeneous and coherent destinations to make the Otherness more accessible for the readers. This process demonstrates how symbolic (re)productions of a territory can give rise to specific constructions of places creating different concepts of region and therefore performative spaces and opportunities of «agency». In other terms the (re)definition of the Sicilian territory proposed by the guide invites tourists to consider a new (narrated) geography invites and invites to interact with it thinking as visitors. From a geographical and cultural point of view reflection on these dynamics allows us to consider some (re)definitions of space in relation to forms of textualization (even on the maps). An imaginary but performative geography that attributes to the concept of territory epistemological and gnoseological possibilities.Settore M-GGR/01 - Geografia
