Mobile Ad Hoc Network (MANET) is an autonomous system of mobile wireless nodes connected dynamically without any preexisting infrastructure. A fuzzy QoS controllers based priority scheduler for mobile ad hoc networks is presented to determine the priority of the packets. The performance of this scheduler is studied using NS2 and evaluated in terms of quantitative metrics, such as packet deliver...

mobile ad hoc networks (manet) are constructed by mobile nodes without access point. since manet has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. the olsr protocol is an optimization of the classical link state algorithm. olsr introduces an interesting concept, the multipoint r...

Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. In this network, this topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Each node acting as both a host and...

ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...

Abstract: Mobile ad hoc network is a collection of wireless mobile hosts which are interconnected by a communication media like radio. The communication network is formed without the aid of any centralized authority or preexisting infrastructure. By its characteristic this type of network is self-starting and self-organizing. It has been observed that mobile ad hoc networks can be exploited for...

1 This work is partly supported by the German Ministry of Education and Research under IPonAir Project Abstract : This paper describes the system design and implementation of a testbed, running at TSystems in Darmstadt. In this testbed the interworking between mobile wireless ad hoc networks (MANETs) and infrastructure based networks, based on the IPv6 protocol is investigated. This means, acce...

Recent advances in wireless networks have enabled us to deploy and use mobile ad hoc networks for communication between the rescue officers in disaster recovery and reconstruction operations. This highly dynamic network does not require any infrastructure or centralized control. As the topology of the network remain dynamic, severe performance limitations incur with traditional routing strategi...

Mobile ad hoc networks are typically characterized by high mobility and frequent link failures that result in low throughput and high end-to-end delay. The increasing use of MANETs for transferring multimedia applications such as voice, video and data, leads to the need to provide QoS support. We introduce a routing algorithm, Ad hoc on-demand multipath routing, which provides quality of servic...

Mobile Ad hoc Networks (MANETs) (Haas et al., 1999) are an important subject for research as mobile devices (laptops, PDAs, cell phones), wireless networks and applications became widespread during the last decade. For instance, specialized ad hoc networks such as the Wireless Sensor Networks (WSNs) (Pottie & Kaiser, 2000; Akyildiz et al., 2002) and the Vehicular Ad hoc Networks (VANETs) (Kosch...

Ad hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. We compare the performance of three routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-Demand Distance Vector Routing (AODV), location-aided routing (LAR1).Our evaluation is based on energy consumption ...
