Transportable nodes in a healthy and demanding network set-up of Mobile Adhoc Network (MANET) are self-governing with self-configurable potential due to high occurrence of topology alteration and changeable rescheduling of the network mechanism during data communication. Due to simplicity of set up, the energetic networking system in MANET is very victorious in conditions where it is complicated to...
Mobile Ad Hoc Networks (MANETs) have been an important research topic for the last years, playing a crucial role within the fast growing sector of mobile communications. At the same time, video applications over mobile devices are becoming widely used by nowadays mobile clients, where the quality in the transmission of such contents will determine the success of these applications in the future. Therefore,...
Mobile ad hoc networks (MANETs) promise unique communication opportunities. The IEEE 802.11 standard has allowed affordable MANETs to be realised. However, providing quality of service (QoS) assurances to MANET applications is difficult due to the unreliable wireless channel, the lack of centralised control, contention for channel access and node mobility. One of the most crucial components of a system...
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...
Mobile ad hoc networks (MANETs) are spontaneously formed with a set of wireless nodes without any existing infrastructure or administrative support. The intrinsic characteristics of these networks such as the dynamic topology and the scarcity of resources mainly bandwidth and nodes battery life make network management process a challenging task. In this paper, we present the design and a performance...
The need for supporting real time and multimedia applications for users of mobile ad hoc network (MANET) is becoming essential. Mobile ad hoc networks can provide multimedia users with mobility they demand, if efficient QoS multicast strategies were developed. The aim of this article is to define the building blocks of such an ad hoc QoS multicasting (AQM) protocol and propose a cross layer framework...
The Ad hoc On Demand Distance Vector (AODV) routing protocol is intended for use by mobile nodes in ad hoc networks. To provide quality of service, extensions can be added to the messages used during route discovery. These extensions specify the service requirements which must be met by nodes rebroadcasting a route request (RREQ) or returning a route reply (RREP) for a destination. In order to provide...
Transporting video over wireless networks has twofold constraints. Not only should it satisfy delay requirements but power minimization and QoS issues should be handled carefully also. Mobile ad hoc networks (MANETs) are more sensitive to these issues where each mobile device acts like a router and thus, routing delay adds significantly to overall end-to-end delay. In this paper, we analyze the performance...
