Communications in highly mobile vehicular networks are challenging and have gained great attention in recent decades. One promising candidate is the IEEE 1609/802.11(p) network standard suite [1][2][3][4][5][6], which is evolved from the commodity 802.11 technology and revised for vehicular environments. Over the non-safety applications in vehicle networks, group communications are expected to enhance the experience and amusement of driving. In this paper, we design and implement a Vehicle Group Communication System (VGCS) over real-life IEEE 1609/802. 11(p) On-Board Units (OBUs). VGCS can track the group members' current locations and broadcast voice/data over a vehicle group, enhancing drivers' and riders' experiences when they cruise together.The performance of the developed VGCS was evaluated in field trials. Our initial experiment results profile the performance of VGCS in a small-scale real-life network and suggest some heuristics for designing a large-scale vehicular application. To the best of the authors' knowledge, in the literature rare papers conducted field trials to study the performance of voice applications over this emerging network. Our experiment data presented in this paper can provide basic understanding for future advanced studies in this area.

An Intelligent Vertical Handover Scheme for Audio and Video Streaming in Heterogeneous Vehicular Networks

In heterogeneous vehicular networks, the most challenging issue is obtaining an efficient vertical handover during the vehicle roaming process. Efficient network selection process can achieve satisfactory Quality-of-Service for ongoing applications. In this paper, we propose an Intelligent Network Selection (INS) scheme based on maximization scoring function to efficiently rank available wireless network candidates. Three input parameters were utilized to develop a maximization scoring function that collected data from each network candidate during the selection process. These parameters are: Faded Signal-to-Noise Ratio, Residual Channel Capacity, and Connection Life Time. The results show that the proposed INS scheme is more efficient at decreasing handover delays, End-to-End delays for VoIP and Video applications, packet loss ratios as well as increasing the efficiency of network selection processes in comparison with the state of the arts.

“…On the other hand, even at fast car speeds (up to 65 mph) it is possible [25] to achieve a 1 Mbps data rate with an IEEE 802.11b system operating with a range of 250 m. Guo et al [11] modeled multiple video sources traveling on a 4-5 lane highway in Atlanta. Video was collected by sending from a car approaching a destination a request trigger to a camera on a remote vehicle passing a destination region.…”

Multimedia exchange within a Vehicular Ad Hoc Network (VANET) may be facilitated by exploiting the peer-to-peer (P2P) paradigm for which a multi-path routing protocol has been designed to reduce packet loss. Urban VANETs are characterized by restricted vehicle mobility, driver actions, and bunching at obstacles, leading to wireless interference and broken links.Similarly P2P communication relies on distributed sources which are intermittently available.However, routing packets over multiple hops and multiple paths still results in packet losses, resulting in poor quality reconstructed video at a receiver. This paper proposes a novel slice compensation scheme employing spatial Multiple Description Coding to provide error resilience as a solution to these problems. Results show constant good-quality video even if packet losses rates increase.
