“…After we present our mathematical model we show in the following description of each QoS item mentioned above. Table 2 Terminology The available bandwidth between two nodes is defined as the maximum throughput at which packets can be transmitted between these two vehicles without disrupting any already ongoing flow in the network (Kaaniche et al, 2011). To improve the QoS provided with our algorithm, we add an estimator of the available bandwidth over a link.…”

Vehicular ad hoc networks (VANET) are gaining popularity for enabling a wide range of applications for road traffic safety, infotainment and road transportation management. For real-time applications to be successfully deployed in VANET, their quality of service (QoS) requirements need to be met. In this paper, we propose a QoS-based routing protocol named FBQoS-Vanet, which accommodates applications with QoS requirements. This protocol uses a bio-inspired artificial bee colony (ABC) approach for discovering routes complying with QoS criteria. We also use fuzzy logic to identify a feasible path among several available ones discovered by ABC. We rely on the evaluation of a composite fuzzy cost expressed in terms of QoS metrics, where the path must satisfy criteria such as: bandwidth, delay, jitter, and link expiry time. The performance results obtained show the benefits of using our scheme for routing various classes of traffic in VANET with different QoS requirements.

Recent years have seen a growing interest in Vehicular Ad hoc Networks (VANETs) and their benefits to the development of intelligent transportation systems (ITS). With the deployment of multimedia services over VANETs, there is a need to develop new approaches to insure higher level of quality of services (QoS) for real time applications, and integrate QoS into routing protocols. However, in VANET environment, it is not an easy task to search for routes which satisfy the QoS required by the applications. In this paper, we propose CBQoS-Vanet, a new QoS-based unicast routing protocol for vehicular networks. This protocol is based on the use of two techniques: a clustering algorithm which organizes and optimizes the exchange of the routing information based on QoS requirements, and an artificial bee colony algorithm, which finds the best routes from a source to a destination based on QoS criteria. In our approach clusters are formed around cluster-heads that are elected based on QoS consideration. In this paper we consider the following QoS criteria: available bandwidth, end-to-end delay, jitter, and link expiration time. Through simulation experiments, we show that our method can improve greatly the performance of routing in VANET by selecting routes based on the above mentioned QoS criteria.

Opportunistic routing has gained much attention as a new and promising approach to relay packets in wireless mesh networks. The collaboration of intermediate nodes to deliver packets without a predetermined route, using the broadcast nature of wireless channel, increases the transmission reliability and network throughput. Nevertheless, such characteristics make the process of admission control even more challenging than in a traditional unipath routing protocol. In this paper, we propose an admission control mechanism for quality of service (QoS)-enabled opportunistic routing protocols. This mechanism performs admission control and resource reservation in multiple neighbors according to their importance for the relaying process. We also consider the influence of using thresholds for QoS parameters in order to improve the service provided to adaptive applications. Simulation results allow us to reach two conclusions: (i) the proposed mechanism achieves higher success rate than both a unipath-based and a multipath-based admission control mechanisms and (ii) thresholds allow high resource reservation even in network topologies with scarce resources.
