“…In this paper, we use WiBro network multimedia data sets of Seoul in Korea as the experimental data set (Han, et al, 2008). It is due to that WiBro network has some similarities with the vehicular networking based on IEEE 802.11p, such as both of them using wireless broadband networks, and belonging to mobile applications.…”

“…Besides, their average uplink bandwidth and downlink bandwidth reach about 5Mbps and 14Mbps respectively at the moving speed of 60 ~ 80km of nodes. Han et al (2008) collects multimedia data from cars and trains at high speed and their multimedia data types include VBR, CBR and VOIP data. And hence, it absolutely can simulate real network traffic data from vehicular networking environment.…”

Failure recovery in Internet of Vehicles (IoVs) is critical to high quality service provisioning. The main challenge is how to achieve fast rerouting without introducing high complexity and resource usage due to the dynamic topology and the constraints on bandwidth. In this paper, we propose a traffic prediction-based fast reroute algorithm for use among the vehicles in IoVs. The proposed algorithm uses the Wavelet Neural Network (WNN) model to predict a vehicle's network traffic. When the predicted value is greater than the predefined network traffic threshold, both Adaptive Retransmission Trigger (ART) that contributes to switch to a better alternate path in advance and trigger efficient retransmission behaviors are enabled successively. Performance comparison of our proposed algorithm with Ant-based Delay-Sensitive Vehicular Routing (AntVehiNet) shows that WNNPFR can: (a) maximize the service data delivery rate by load balancing, (b) provide high quality of service delivery for multimedia streams by switching to a better path towards a target node in advance, (c) reduce useless data retransmissions when various network failures occur, and (d) maintain lower routing overhead.

An efficient uplink transmission scheduling algorithm with reduced interference and outage for IEEE 802.16j relay networks

Uplink scheduling for relay stations in mobile multi-hop relay network has not been widely addressed in the literature under common belief that downlink traffic overwhelms uplink traffic.Recently, data traffic from user created content (UeC) is rapidly growing with a potential to create a huge amount of uplink (UL) traffic. Overlapped resource allocation in uplink transmission allows MSs attached to different RSs can reuse the same frequency band to increase the network throughput. However, the uplink traffic from MSs located on the boundary between two neighboring RSs may cause interference to each other RS.The interference degrades the uplink throughput or even leads to service outage for MSs located on the boundary, resulting in poor fairness in QoS among subscribers. We propose an uplink transmission scheme with reduced interference. We reduce the interference by grouping MSs in such a way the uplink transmission from the MSs in a group do not interfere each other at the receiving RSs. Simulation results show that the proposed scheme removes service outage by 61.5% and increases average throughput by 13.3% compared with a simple overlapped resource allocation scheme(similar to the overlapped resource allocation scheme for downlink transmission). In terms of fairness, the proposed scheme excels by 38.7% the simple overlapped scheme.
