Because of high mobility and resource constrains in mobile ad hoc network (MANET) environment, a lot of challenges are encountered in effective routing such as quality of service (QoS). In this paper, the ad hoc on-demand distance vector (AODV) routing protocol is revised by calculating the corresponding QoS provision values to find the best routes and applying the mechanism of carrier sense in IEEE...
In this paper we propose admission control and multipath routing algorithm for differentiated services (DiffServ) based networks (ACMRA). The basic DiffServ architecture lacks the admission control mechanism thus injecting more QoS sensitive traffic into the network can cause congestion at the core of the network. ACMRA combines the admission control with route finding phase and our routing protocol...
Wireless mesh networks (WMNs) have recently gained a lot of popularity due to their rapid deployment and instant communication capabilities. However, as a key technology for next-generation wireless networking, WMNs lack suitable routing metrics and protocol for new features. Currently, AODV is the routing protocol used in WMNs. This paper proposes an ants-in-mesh (AIM) routing protocol for wireless...
A Mobile Ad hoc NETwork (MANET) consists of a collection of mobile nodes. As MANETs are gaining popularity day-by-day, new developments in the area of real time and multimedia applications are rising as well. Such applications require Quality of Service (QoS) evolving in terms of the constraints such as bandwidth, end-to-end delay, jitter and energy. QoS provisioning for MANET can be achieved over...
Ad hoc networks are collection of mobile nodes which communicate using wireless media without any fixed infrastructure. Each mobile host acts both as a network router and an end point as packets are forwarded over multiple hops. Node mobility being the distinguishing feature of the mobile ad hoc network, makes routing an important challenge. Hence, Quality of Service (QoS) is not easily achieved in...
In the current routing mechanism for Mobile Ad hoc Networks, service differentiation is not realized completely, resulting in resources wastage for best-effort (BE) traffic and deficiency for real-time traffic, such as voice and video. A novel service differentiated multi-path routing mechanism is proposed, in which service differentiation is realized in network layer based on multi-path routing....
Attempt to achieve multicast reliability in adhoc networks is usually foiled during tree/mesh reconfiguration - a frequent repair activity. This has impaired the quality of packets delivered during transmission via a protocol that requires partial/complete knowledge of the group location. Bimodal multicast employed gossip techniques, and we extended this concept by proposing anonymous gossip, in our...
We propose a novel, energy-aware, routing protocol for quality-of-service (QoS) support in an infrastructure-less ad-hoc network. Our stability-based, QoS-capable ad-hoc on-demand distance vector (SQ-AODV) protocol is an enhancement of the well-known ad-hoc on-demand distance vector (AODV) protocol. Our protocol utilizes a cross-layer approach, in which information about residual node energy is used...
Significant efforts and studies were recently reported for enabling active safety, traffic management, and commercial applications in Vehicular Ad Hoc Networks (VANET), since these applications are the drivers of the recent surge in VANET research and development. However, very few research efforts considered analyzing the Quality of Service (QoS) metrics that will be available to these applications...
Providing high quality communications service among mobile wireless devices is basically a challenging task in wireless ad hoc networks. In this paper, we propose a route stability based multipath quality of service (QoS) routing (SMQR) protocol for mobile ad hoc networks (MANETs) to support throughput and delay sensitive real-time applications in MANETs. Reliability of QoS-aware path is improved...
In this paper an efficient on demand QoS based routing protocol is developed which considers end to end application requirement and energy efficiency together with the route discovery mechanism of DSR to set up QoS route. The proposed QoS aware protocol works as per the user request for a route. If a request comes for QoS route, based on some application requirement (available bandwidth, transmission...
Due to the dynamically varying network topology ofad-hoc networks, the admitted quality of service suffers from frequent path breaks that require network re-establishment over new paths. Thus, rendering ad-hoc networks inappropriate for real-time interactive sessions, e.g., video or audio calls. TORA is a distributed, loop-free, multipath routing protocol for multi-hop networks which supports both...
Due to the dynamic nature of mobile ad-hoc networks (MANETs), there are many issues which need to be tackled. One of the areas for improvement is quality of service (QoS) routing. Various approaches and enhancements have been proposed including QoS-AODV. It is proposed to enhance one of the existing routing protocols for MANET namely AODV (ad-hoc on-demand distance vector). In QoS-AODV the original...
This paper proposes QoS Mesh routing protocol for IEEE 802.16 based wireless mesh networks. QoS Mesh Routing Protocol proposed in this paper is a proactive hop-by-hop QoS routing protocol. The goal of our protocol is not only to find routes from a source to a destination node, but also optimal routes that satisfies QoS requirements, given in terms of bandwidth and delay as default QoS parameters....
Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. A major challenge lies in adapting multicast communication to environments where mobility is unlimited and failures are frequent. The multicasting concept deals with one to many data dissemination, many multicast routing algorithm have been proposed like ODMRP, CAMP, NTPMR and so on. In this paper we design...
