In Mobile Ad hoc NETworks (MANETs), accurate throughput-constrained Quality of Service (QoS) routing and admission control have proven difficult to achieve, mainly due to node mobility and contention for channel access. QoS related with band width utilization is very interesting because band width is the most critical resource in mobile ad hoc networks. The QoS issue must also be studied with a growing node density. This is because the beauty of attaining wider band width link is highly appreciated when the band width resource is scarce due to congestion and high traffic. In this paper, a comparative analysis of two proactive protocols: Destination Sequence Distance Vector (DSDV) and OLSR (Optimized Link State Routing) is conducted in their traditional best effort routing part.
