Unified Support for Quality of Service Metrics Management in Mobile Ad Hoc Networks Using OLSR

This article focuses on technical issues related to quality of service provisioning at routing layer in ad hoc networks. It describes the design and implementation of a unified support for quality of service (QoS) metrics within the routing protocol OLSR. This is achieved by the extension of both signalling messages and route calculation process. Major benefits of the proposed approach are to allow dynamic enforcing and adaptation of QoS metrics according to policies defined into the network. QoS metrics information are inserted in a generic way within OLSR signalling messages taking advantage of Linux kernel plugins. These messages are used by the routing process in order to compute routes with respect to the chosen QoS metrics.
