The constant mobility of individuals and the necessity of staying connected makes studying the possibilities of connectivity and transmission of information between vehicles one of the main objectives of the cars manufacturers. The social costs that accompany this development -increase in accidents, congestion of cities, etc.- increases the needing of improving car safety by providing information on road traffic conditions and also making interesting the study of VANETs (vehicular ad hoc networks) by the authorities and the administration. Anonymity is a key concern in this kind of network, guaranty that the identity of a message sender is protected is an important challenge and might be a mandatory feature for some VANET applications. For this purpose, we introduce Crowd, an anonymity protocol that provides a mechanism for anonymous Web browsing. The main idea behind Crowd anonymity protocol is to hide each user's communications by routing them randomly within a group of similar users. Consequently by using the Crowd protocol neither the receiver nor a corrupt group member or local eavesdropper that observes a message being sent by a particular user can never be sure whether the user is the actual sender, or is simply routing another user's message. The main objective of this PFM is to design and implement an anonymity solution based on the Crowd anonymity protocol to work in a VANET environment, and later on to evaluate QoS and Privacy metrics under this condition. Such evaluation is done by implementing realistic vehicular network scenarios with the network simulator NCTUns and perform different simulations for making a performance evaluation, analyzing packet lost, end-to-end delay and the throughput as a function of the Crowd protocol parameters.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [ANGLÈS] There are unlimited opportunities for civilian car to car application for VANETs. The priority research field for Car Manufacturers as well as Governmental Transportation Authorities is the safe navigation. Applications that may be able to inform the neighbouring vehicles about weather, road condition, traffic jams, and accidents can save many lives and also optimize the resources for emergency, improve the respond time to emergency among others important applications. Some of these applications will require security information services to promote its use. One of the most important security information services for the application usability in VANETs will be the privacy, more explicitly 'Anonymity' in the sense if someone wants to collaborate notifying emergencies, traffic state, suspicious driver behaviour, necessarily he/she will require to send for instance his/her estimated position but without being tracked. Base in this fact, this Final Master Project tests the suitability of anonymity web mechanism called Crowds over routing protocols in vehicular Ad Hoc Networks. A Crowds variant that does not consider self-forwarding specially adapted for VANETs is implemented over AODV (a reactive topology routing protocol) and a GPSR variant (a well-known position-located routing protocol) that includes the use of a buffer and building aware condition to select its forwarding nodes. Simulation tests were done using NCTuns 6.0 for a single hop scenario to measure the accuracy of the formulas obtained for ideal cases of Crowds, and evaluate its performance in a real multi hop scenario focusing in the End Server attack. Finally, results and future works related to improve this simple and promissory anonymity mechanism over VANETs are provided.

This book was released on 2012-08 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ad hoc network is a collection of autonomous mobile nodes to forming an instant multihop radio infrastructure-less network in a dynamic topology. Many routing protocols for mobile ad-hoc networks are presented since last decade.Ad-hoc networks are in a great demand now a days and have a lot of advantages.In this direction, we have designed the Ad Hoc On Demand Routing Protocol (AODV) using Network Simulator (NS) which is efficient as well as we have implemented the security technique so the we can prevent the data loss at the time of transmission. The main advantage of using the Network Simulator for the design of AODV is that we can actually observe the working of the specific protocol without the establishment of the network as NS provides the environment for the working of protocol. In this paper, we provided the security to the AODV routing protocol using asymmetric Cryptography with the help of RSA algorithm.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

This book was released on 2011 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The flexibility of movement for the wireless ad hoc devices, referred to as node mobility, introduces challenges such as dynamic topological changes, increased frequency of route disconnections and high packet loss rate in Mobile Ad hoc Wireless Network (MANET) routing. This research proposes a novel on-demand routing protocol, Speed-Aware Routing Protocol (SARP) to mitigate the effects of high node mobility by reducing the frequency of route disconnections in a MANET. SARP identifies a highly mobile node which forms an unstable link by predicting the link expiration time (LET) for a transmitter and receiver pair. When the nodes have high relative velocity, the LET calculated is a small value; this means that the link is predicted to disconnect before the successful transmission of a specific demand. SARP omits such a packet-sending node from the link route during the route discovery phase. The omission of such unstable links helps SARP limit the flooding of control packets during route maintenance and reduces the overall control overhead generated in on-demand routing protocols. NS2 was used to implement the SARP with ad hoc on-demand vector (AODV) as the underlying routing algorithm. Extensive simulations were then conducted using Random Waypoint Mobility model to analyze the performance of SARP. The results from these simulations demonstrated that SARP reduced the overall control traffic of the underlying protocol AODV significantly in situations of high mobility and dense networks; in addition, it showed only a marginal difference as compared to AODV, in all aspects of quality-of-service (QOS) in situations of low mobility and sparse networks"--Abstract, leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Vehicular ad hoc networks (VANETs) can provide scalable and cost-effective solutions for applications such as traffic safety, dynamic route planning, and context-aware advertisement using short-range wireless communication. To function properly, these applications require efficient routing protocols. However, existing mobile ad hoc network routing and forwarding approaches have limited performance in VANETs. This dissertation shows that routing protocols which account for VANET-specific characteristics in their designs, such as high density and constrained mobility, can provide good performance for a large spectrum of applications. This work proposes a novel class of routing protocols as well as three forwarding optimizations for VANETs. The Road-Based using Vehicular Traffic (RBVT) routing is a novel class of routing protocols for VANETs. RBVT protocols leverage real-time vehicular traffic information to create stable road-based paths consisting of successions of road intersections that have, with high probability, network connectivity among them. Evaluations of RBVT protocols working in conjunction with geographical forwarding show delivery rate increases as much as 40% and delay decreases as much as 85% when compared with existing protocols. Three optimizations are proposed to increase forwarding performance. First, one- hop geographical forwarding is improved using a distributed receiver-based election of next hops, which leads to as much as 3 times higher delivery rates in highly congested networks. Second, theoretical analysis and simulation results demonstrate that the delay in highly congested networks can be reduced by half by switching from traditional FIFO with Taildrop queuing to LIFO with Frontdrop queuing. Third, nodes can determine suitable times to transmit data across RBVT paths or proactively replace routes before they break using analytical models that accurately predict the expected road-based path durations in VANETs.
