Adaptive QoS Routing by Cross-Layer Cooperation in Ad Hoc Networks

Free registration required

Executive Summary

QoS provisioning is a complex and challenging issue in mobile ad hoc networks, especially when there are multiple QoS constraints. In this paper, authors propose an adaptive QoS routing scheme supported by cross-layer cooperation in ad hoc networks. The cross-layer mechanism provides up-to-date local QoS information for the adaptive routing algorithm, by considering the impacts of node mobility and lower-layer link performance. The multiple QoS requirements are satisfied by adaptively using forward error correction and multipath routing mechanisms, based on the current network status.
