| dc.description.abstract | Dealing with Quality-of-service (QoS) routing in a mobile Ad-Hoc network is difficult due to the fact that the network topology changes constantly and the available link state information for routing is naturally indefinite. 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 thesis, 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. Evaluation of their performance is compared against with band width management metrics. Based on the result of the comparative analysis we develop QoS versions of the OLSR protocol. Algorithm is introduced that allow OLSR to find the maximum bandwidth path with optimal number of MPR, show through simulation and proof that this algorithm do improve QoS in the aspect of bandwidth using (Network Simulator-2) NS-2 simulator and observe the achievement obtained. The simulation results show that the QoS versions of the OLSR routing protocol do improve the available bandwidth ensuring about 2%-16.78% enhancement of Goodput and 2.5- 15.06 % of PDF, this is verified in a network scenario of different node density and node mobility when compared to Original OLSR.
