“…Therefore, an RSU re-routing strategy is needed to alter the multi-hop transmission messages from one RSU to another to reduce wireless multi-hop transmission delay for delay-sensitive applications in the VWNs. Much research [3][4][5][6] deals with 802.11 handoffs to reduce the delay of handoff phases for roadside networks that deploy IEEE 802.11 WLAN access points (APs) along the roadside. Chen et al [7] propose a DeuceScan scheme to reduce the probe delay and to improve wireless communication qualities for fast handoff in IEEE 802.11 WLAN.…”

Summary Vehicular wireless networks offer wireless multi‐hop communications between vehicles and roadside units (RSUs). To reduce deployment cost, the distance between two RSUs could be long; that is, the communications between an RSU and a vehicle may be carried out through multi‐hops among intermediate vehicles. When a vehicle is driven from one RSU to another, the wireless multi‐hop delay becomes more serious as the number of multi‐hop relays increases. The wireless multi‐hop delay is critical for some emergency service. For instance, in a traffic accident, when a patient was sent to the hospital by ambulance, the life information of the patient must be transmitted to the hospital on time through the multi‐hop wireless network. If the ambulance is moved from one RSU to another, the wireless multi‐hop delay becomes more and more serious as the ambulance is closing to another RSU. In this paper, we propose an RSU re‐routing strategy that dynamically alters multi‐hop communications until the best RSU with the shortest path using location information is found. Moreover, we compare the proposed strategy with the existing strategy in terms of broadcasting costs, re‐routing delay, and wireless multi‐hop delay of data transmission. Performance results show that the proposed strategy can reduce the wireless multi‐hop delay significantly. Copyright © 2014 John Wiley & Sons, Ltd.

“…Recent advances in wireless radio resource management, as proposed by the IEEE 802.11k Meschke et al (2010) Working Group, are aimed at improving the distribution of multimedia content within a network, where the mobile user can connect to the access point (AP) that provides the best QoS/QoE support and not only the strongest signal. Other approaches have been proposed to support seamless mobility for multimedia applications, such as pre-fetch and cache-based multimedia schemes, self-adaptive handover management solutions for mobile streaming continuity, and content-oriented mobility schemes.…”
