چکیده
Adaptive applications are a key concept to take into account when dealing with multimedia internetworking in wireless and mobile environments, in which network conditions may change abruptly and not always due to congestion –as it happens in fixed networksbut also to interference, mobility and so on. This paper presents an adaptation architecture which allows applications to minimize the impact of adverse and changing network conditions, by using self-adjustment techniques at high layers, obtaining information from the network. The objective is maintaining the QoS perceived by the user at an acceptable level. Results are presented by means of some tests in different test-case scenarios.

متن کاملIntelligent and adaptive middleware to improve user-perceived QoS in multimedia applications
We investigate the use of adaptive multimedia applications to improve the user-perceived QoS in next-generation wireless networks. These networks will be characterized by the heterogeneity of the access technologies including ad hoc wireless network extensions. In these network scenarios in which the links are error-prone, their capacity is extremely variable and even the topology can change du...

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...
متن کاملQoS-Aware Routing Based on Adaptive-Gossip Algorithm for Conserving Resource in Ad Hoc Wireless Networks
In ad hoc wireless networks (AWNs), the provision of Quality of Service (QoS) guarantees is much more challenging than in conventional wireless networks, mainly due to node mobility, multihop communications, contention for channel access and a lack of central coordination. Typically multimedia applications have delay-sensitive and high bandwidth requirements, especially for shared wireless chan...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
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...
