Intelligent Transport System (ITS) has become a hot research topic over the past decades. ITS is a system that applies the following technologies to the whole transportation management system efficiently, including information technique, wireless communication, sensor networks, control technique, and computer engineering. ITS provides an accurate, real time and synthetically efficient transportation management system. Obviously, Vehicular Ad Hoc NETworks (VANETs) attract growing attention from both the research community and industry all over the world. This is because a large amount of applications are enabled by VANETs, such as safety related applications, traffic management, commercial applications and general applications. When connecting to the internet or communicating with different networks in order to access a variety of services using VANETs, drivers and passengers in different cars need to be able to exchange messages with gateways from their vehicles. A secure gateway discovery process is therefore critical, because vehicles should not be subject to security attacks while they are communicating; however, currently there is no existing protocol focusing on secure gateway discovery. In this thesis, we first analyze and compare current existing secure service discovery protocols and then we propose a Secure Gateway Localization and Communication System for Vehicular Ad Hoc Networks (SEGAL), which concentrates on the security issue in gateway discovery. We focus on the authentication aspect by proposing secure cluster based VANETs, that can ensure the gateway discovery messages exchanged through secure clusters. We present the principle and specific process of our SEGAL protocol and analyze its performance to guarantee its outstanding practical applicability.

Many destinations throughout the world have developed events portfolios as a strategic initiative to attract tourists and their associated economic benefits. The ability of events to attract people to a destination for the purpose of attending the event is well documented. However the ability of an event to add value to attract tourists before or after the event is not so clear. In other words, can an events portfolio positively influence the decision to visit a destination at a time when none of the promoted events are scheduled? As a first step towards answering this important question, this study explores the contribution of an events portfolio to a consumer’s perceptions of a destination and how this influences their decision to attend a destination under these circumstances. The proposed study conducts a protocol analysis based on consumer’s decision-making thoughts. Each participant was given a choice between two destinations in India. Participants were asked to ‘think out loud’ as they made the decision to visit one of two possible destinations, one with an events portfolio and the other without. However, their visit does not coincide with the events’ dates. The results suggest four lines of reasoning utilised by prospective tourists in the destination choice process: 1) destination image; 2) the timing of the event with respect the time of visit; 3) tourists’ level of interest in the event; and, 4) events not listed in the events portfolio might be scheduled during the time of the proposed visit. In course of finding lines of reasoning for cross-cultural issues it was found that culture, architecture, English language usage, and food are the major aspects that tourists consider while travelling to Indian destinations. In terms of the events portfolio, there is evidence of a preference for a ‘fit’ between the event and Indian culture.
