“…The application-layer Chord network of both QUVoD and VMesh are implemented based on the MChord [19]- [20], extended according to their different individual algorithms. For QUVoD, we consider two wireless communication interfaces for each of the vehicle nodes: the IEEE 802.11p WAVE network interface and 4G WiMAX interface.…”

“…For example there are five substrings: {1, 2, 3}, {7, 8, 9}, {11, 12, 13}, {16, 17}, {20} in the first entry in the k-entry log [1,2,3,7,8,9,11,12,13,16,17,20] in table I. Even if a single segment playback occurs in a log, it is also considered as a substring such as the case for 20.…”

Abstract-Recently many cities around the world have witnessed large scale deployment of terrestrial broadcasting mobile TV to vehicles. This service is similar to the cable or satellite television already watched at home and user-centric interactive mobile Video-on-Demand (VoD) over urban vehicular networks is in fact expected. However providing this new service with focus on user Quality of Experience (QoE) constitutes a significant challenge. This paper introduces a QoE-driven User-centric solution for VoD services in urban vehicular network environments (QUVoD). QUVoD relies on a multi-homed hierarchical peer-topeer (P2P) and vehicular ad-hoc network (VANET) architecture. Vehicles construct a low layer VANET via WAVE interfaces and also form an upper layer P2P Chord overlay on top of a cellular network via 4G interfaces. A novel grouping-based storage strategy is proposed which distributes uniformly the video segments along the Chord overlay, reducing segment seeking traffic, while also enabling load-balancing. A novel segment seeking and multipath delivery scheme is also introduced which achieves high lookup success rate and very good video data delivery efficiency. Furthermore, a new speculation-based prefetching strategy is proposed, which analyses users' interactive viewing behavior and, by estimating video segment playback order, employs pre-fetching of the expected segments, smoothening the video playback. Simulation results show how QUVoD is a highly efficient user-centric mobile VoD solution in urban vehicular networks in comparison with existing state of the art solutions.Index Terms-User-centric VoD, peer-to-peer (P2P), quality of experience (QoE), vehicular network.

“…However, given hundreds of highways miles at which there is hardly enough budget to maintain and install lights on the roads, installing gateways every 2-10 miles will be very expensive and not a practical solution. Liu et al [9] proposed Mobile Chord (MChord), an enhancement of P2P performance over VANETs.…”

Abstract-Vehicular Ad Hoc Networks (VANETs) are a form of Mobile Ad Hoc Networks (MANETs) in which vehicles on the road form the nodes of the network. VANETs provide several services to enhance the safety and comfort drivers and passengers. One of the services that VANETs can provide is file sharing between vehicles. Sharing large scale files through the network is a challenging task. Therefore, developing an efficient peer-to-peer (P2P) file sharing scheme is important. This paper presents a P2P file sharing scheme for VANETs using TC-MAC, a MAC algorithm for vehicular ad-hoc networks using Time-Division Multiple Access (TDMA) slot reservation based on clustering of vehicles. Using TDMA will reduce collisions and packet drops in the channel, as well as provide fairness in sharing the wireless medium and minimizing the effect of hidden terminals. Our work aims to develop a P2P file sharing algorithm to improve the file downloading time between neighbouring vehicles.

“…A service architecture over VANETs was proposed in [1] to provide users with time-sensitive information regarding traffic conditions and roadside services. In [2], vehicles construct an application-layer peerto-peer (P2P) overlay network on top of VANETs to support content delivery in vehicular networks. However, these VANET-based systems require a sufficient number of vehicles participating in VANETs.…”

With advances in information and communication technologies, vehicles on roads can cooperatively share and retrieve information in a distributed manner to support Intelligent Transportation Systems (ITS) services such as traffic management and infotainment services. A system is needed to retrieve information and data from moving vehicles and roadside facilities in an efficient manner. However, existing distributed vehicular systems rely on either vehicular ad hoc networks (VANETs) or application-layer peer-to-peer (P2P) protocols over an infrastructure-based wireless network suffering from low success rate or long latency in information retrieval. In this work, we propose a two-tier VANET/P2P system that integrates low-tier VANETs and a high-tier infrastructure-based P2P overlay. The proposed two-tier system aims to achieve high success rate, reduce latency, and minimize overhead for information retrieval in vehicular environments.
