  Therefore, this method meets the Qos of energy efficiency and low delay. Su et al. proposed an enhanced mobility and temperature-aware routing protocol, and this protocol takes three routing metrics: hop count, temperature and link quality to select the best next hop. The disadvantage is that the energy consumption of nodes is not considered. Delay is an important QoS parameter for timely delivery of event information in delay sensitive applications of wireless sensor networks. In this paper, we propose a delay aware routing protocol for wireless sensor networks with mobile base stations.

The QoS routing protocols work based on QoS metrics. The QoS routing is a modular-based protocol where synchronization and network density make it difficult to enhance the QoS protocol. In WBAN, patients’ data (critical or normal) is considered very important and transmitted efficiently and securely based on QoS metrics. The routing protocols belonging to the third category can be further classified as source initiator routing protocol and destination initiator routing protocol. The proposed survey presents the comparison of different routing protocols for WSNs which helps the readers to choose the efficient routing protocols for wireless sensor network.

  This is a survey paper on Quality-of-Service(QoS) based routing. In this paper, we first introduce the concept of Quality-of-Service and its background. Combining a resource reservation protocol with QoS-based routing allows fine control over the route and resources at the cost of additional state and setup time. [Ma98] Q. Ma, "Quality. along with the highlights of the advantages and performance issues of each routing protocol and algorithm. In addition, the paper concludes with classification of recent real-time routing protocols and discusses open research issues. Keywords: Wireless sensor networks, real-time, routing protocol, survey. 1. Introduction.

Routing Protocol Classification and Improving QOS Metrics: A Survey Download PDF EPUB FB2

At present, the research on routing protocols for WBAN is mainly divided into the following methods [14,15], and this paper refers to the classification method presented by Bangash et al., (as shown in Figure 3) posture-based routing, temperature-based routing, cross-layer routing, QoS-based routing, and cluster-based by: 9.

A careful blend of such metrics in a routing cost function guarantees a committed level of QoS. This survey uses number of routing metrics as criteria for categorizing state-of-the-art QoS WMSNs routing techniques.

In addition, open issues and future research directions to further develop efficient routing protocols to guarantee QoS are by: This paper surveys recent routing protocols for sensor networks and presents a classification for the various approaches pursued. The three main categories explored in this paper are data-centric, hierarchical and location-based.

Each routing protocol is described and Cited by: End-to-End QoS Routing protocols the survey of routing protocols for wireless mesh networks and their efficiency including the impact of routing metrics. Routing protocols are crucial element. RSQR protocol: RSQR (Route Stability based QoS Routing) (Sarma and Nandi, ) is a QoS routing protocol based on link stability.

The problematic posed by the authors is to find the most stable path between a source and a destination while satisfying the constraints of the minimum bandwidth and the acceptable end-to-end by:   QoS based routing protocols. To get good Quality of Service these protocols are used. QoS aware protocols try to discover path from source to sink that satisfies the level of metrics related to good QoS like throughput, data delivery, energy and delay, but also making the optimum use of the network resources.

Examples are: [4, 6]. One of the most used QoS aware protocols is data-centric multi objective QoS-aware routing protocol (DMQoS) because it can decrease the delay for delay-sensitive information, and similarly, it can provide reliable routing for reliable-sensitive information.

The other QoS-aware protocols are used or selected for a particular network, according. These metrics are suitable for Quality of Service (QoS) requirements of applications.

Findings: Traditional multipath routing protocols operate only in Network layer and utilize a static routing metric which leads them to be unable to give route priority to different traffic classes from Application layer. The QoS routing protocol should respond quickly in case of path breaks and recompute the broken path or bypass the broken link without degrading the level of QoS.

In the literature, numerous routing protocols have been proposed for finding QoS paths. In the following sections some of these QoS routing protocols are described. Routing Protocol: The routing protocol stores the delay and variance of the minimum cost path to each known destination as defined by a message-independent cost metric.

A separate routing table is constructed at each node i for each vertex ij (i.e., for each vertex in the inter-contact graph that refers to an encounter of node i with one of its. On the basis of the principle of protocol operation, routing protocols can be classified into multipath-based, query-based, negotiation-based, QoS-based, and coherent-based routing techniques.

Furthermore, the authors in [26] expanded the classification of routing protocols in [27] as shown in Fig. 1 and proposed three other principles.

QoS-Aware Routing Protocols. The QoS-aware routing protocols are modular-based protocols and use different modules for different types of QoS metrics. The design of these protocols is a challenging job, due to the complexity of considering different modules for different QoS metrics and coordination between these modules.

It ensures uniform energy consumption and meets QoS constraints. Routing Protocols Addressing Different Types of Algorithms. Yao et al. propose a routing protocol that uses metadata to construct multipath routing to meet QoS metrics.

The proposed protocol uses advanced Dijkstra algorithm and cost function to make routing decision. consider QoS-Aware protocols, which take into account energy consumption and data quality.

The network may have to satisfy certain QoS metrics (delay, energy, bandwidth) when delivering data to the base station, metrics which are used in the QoS-Aware protocols. Table 1 lists the routing algorithms and classes that we review in this paper. The study of routing protocols in wireless sensor networks has been addressed to improve the usage of limited network resources.

In this paper, we give in detailed survey of flat routing protocols. protocols proposed for energy efficient routing. A survey of applications on sensor networks focuses on QOS needs and routing protocols which satisfy the QOS needs is also studied[2].

It is a broad classification of protocols of WSN. Although a variety of routing protocols are covered [1][2], but.

In turn routing technique must provide reliable transmission of data without compromising QoS requirements of applications. We have addressed different routing protocol categories with range of QoS metrics to be achieved, to improve performance of WSNs applications.

QoS routing protocols in MANETs are surveyed and analysed in many papers (Asokan, ;Harle et al., ;Chen and Heinzelman, ;Hanzo and Tafazolli, ) and an overview of fuzzy-based QoS.

Comparison among the Routing Protocols and Open Issues. Our survey shows that each of the various routing protocols has its own strengths and weaknesses, the chief reason being that the design of protocols depends mainly on the different objectives. We summarize recent results on routing protocols in large-scale WSNs in Table 1.

The table. A survey on routing protocol and gateway discovery in Vehicular Adhoc NETwork(VANET) Hop count is an essential routing protocol used this metric for routing in multi hop communication for gateway selection.

However, the gateway can become Improve qos, Improve network throughput, Increase the packet delivery ratio. To compare the performance of AODV and DSDV routing protocol, the simulation results were analyzed by graphical manner and trace file based on Quality of Service (QoS) metrics.The proposed protocol focuses on medical applications, by considering its traffic diversity and providing a differentiation routing using quality of service (QoS) metrics.We focus in this survey paper on QoS routing protocols with a discussion of their classification, strengths and weaknesses, deployment of QoS protocols in particular applications and research directions for improving the QoS routing protocols.
