The current trend of connectivity anywhere, anytime, and any how brings a newrnparadigm of accessing multimedia services (voice, video, and text) via MANETsrnspecifically in areas of military, emergency, automotive application e.t.c. However, thernavailable bandwidth for supporting these applications is rather limited, and properrnmanagement of the bandwidth is necessary to accommodate the envisaged highbandwidthrnapplications and, thus, provide QoS. In other words it is a must to have QoSrnsupport routing protocol that find a feasible path between source/destination pair (i.e. arnpath that has sufficient available resources capable of satisfying the QoS requirements).rnIn this work, a survey on selected best effort routing protocols (OLSR, DSDV, andrnAODV) is conducted using qualitative and quantitative multi metrics and showsrnprotocols that work in proactive mode are more suitable for QoS routing than reactivernones. Since routes are maintained, proactive protocols have lower latency where asrnreactive protocols may have higher latency because a route from source to destination will be found only when sender attempts to send to the receiver. However, proactivernprotocols can (but not necessarily) result in higher overhead due to continuous routernupdating. The result finally shows OLSR is a good candidate for QoS improvement.rnTherefore, reengineering of best effort OLSR proactive protocol using new MPRrnselection approach is found as the best alternative to add QoS features and the result isrna corresponding QoS Aware version of OLSR. Even though a number of variantrnapproaches are available, they are not optimal in selecting MPRs covering 2 hoprnneighbors and a good quality links. Therefore, we have devised a new selectionrnmechanism that takes in to account the number of MPRs and bandwidth to have arnrelatively better QoS support. With the help of scenario based simulation analysis, wernfinally proved that QoS aware OLSR is better than the original OLSR in delivering QoSrnservices. Thus, the algorithm we proposed in architecting QoS Aware OLSR showsrnimprovement to the best effort OLSR in terms of QoS support.rnKey words: MANETs, Qos Routing, best effort OLSR, QoS Aware OLSR, MPR
