Ad hoc networks have characteristics such as flexibility, fast and easy deployment, robustness which make them an interesting technology for various applications. Ad hoc networks are considered as the most promising terminal networks in future mobile communications. Providing sufficient bandwidth for multimedia applications in ad hoc networks is an urgent task because of the rising popularity of multimedia...
Due to a continued increase in the speed and capacities of computing devices, combined with our society's growing need for mobile communication capabilities, multihop wireless networks (MWNs), such as wireless mesh networks (WMNs), have gained a lot of interest from the research community. Quality of service (QoS) provisioning in these networks is an essential component that is needed to support multimedia...
With the increasing development of real-time and multimedia applications, there is a need to provide bandwidth and delay guarantees. Existing QoS ad hoc network routing protocols select path guaranteeing delay and/or bandwidth. However, they don't consider throughput optimization, which results in a low number of admitted real-time and multimedia flows. In this paper, we propose a cross-layer TDMA-based...
Jiter is referred as the variability of latency in packets over a period of time. In mobile network, topology changes rapidly which causes a reconfiguration of network. Therefore the latency of transmission also varies. It gives rise to a QOS problem as predicting exact latency is difficult. Hence time bound or real time packets can not be guaranteed highest QOS in MANET. It this paper we propose...
Wireless mesh backbones (WMBs) provide promising solutions for future networking strategies. Due to the mesh nature and thus the resource restrictions of such backbones the integration of mobility aware preloading mechanisms is essential for QoS provisioning, especially in environments with high mobility clients. This paper presents a novel concept, called mobility-aware forwarding in advance (MAFIA),...
The multicast routing model is set up by hybrid routing protocol, Aiming at the mobile network topology and the characteristics of multicast routing based on QoS. A multicast tree meeting the QoS constraints, consumption tend to a minimum and stable form is set up based on ant colony algorithm. Experiments show that the algorithm has a better performance than the other algorithm.
Devising a solution for the provision of quality of service (QoS) in a mobile ad hoc network is a challenging task. In this paper, we propose a routing protocol with a provision of QoS. Our protocol tries to discover multiple node-disjoint paths between a given source and a destination and tries to utilize them for a desired level of QoS. In our protocol, nodes along paths are aware of the correlation...
This paper has introduced several QoS routing protocols in the ad hoc networks. And it elaborates the development tendency in the future through comparing several important QoS routing protocols in the ad hoc networks.
The ad hoc network is a non-infrastructure mobile network that consists of many mobile nodes. Since the nodes have a mobility features in ad hoc network, the ability of communication between the nodes is limited by nodespsila power. The power consumption and bandwidth of each mobile node becomes an important issue and needs to be addressed. The paper discusses the energy efficient routing problem...
Mobile ad hoc networks (MANET), which comprise of mobile nodes connected wirelessly, are emerging as a very important technology for future generation of wireless mobile and ubiquitous computing. MANETs are being used in numerous application domains from emergency rescue and relief to wireless sensor networks. To support real-time communications (such as audio and video) over MANETs, new quality of...
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...
