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.
A New Metaheuristic for the Vehicle Routing Problem with Split Demands
2007
In this paper we present a metaheuristic procedure constructed for the special case of the Vehicle Routing Problem in which the demands of the 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 results obtained compare with 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…
