Supporting Internet Access and Quality of Service in Distributed Wireless Ad Hoc Networks

  title={Supporting Internet Access and Quality of Service in Distributed Wireless Ad Hoc Networks},
  author={Ali Hamidian},
In this era of wireless hysteria, with continuous technological advances in wireless communication and new wireless technologies becoming standardized at a fast rate, we can expect an increased interest for wireless networks, such as ad hoc and mesh networks. These networks operate in a distributed manner, independent of any centralized device. In order to realize the practical benefits of ad hoc networks, two challenges (among others) need to be considered: distributed QoS guarantees and multi… 

Improving Video Transmission over Heterogeneous Networks

A new algorithm that is integrated into the AQA-AODV routing protocol in order to improve the interoperability between MANETs and wired networks (heterogeneous networks) is presented and it is revealed that the rate-adaptive strategy helps avoid or reduce the congestion obtaining an improvement of the received video quality.
