EVALUATION OF TWO QoS SUPPORT ALGORITHMS IN AD HOC NETWORKS ENTITLED PA AND QPART
Today, support of quality of service in ad hoc networks is the topical issue among the network science researchers. Several different algorithms and methods were proposed to differentiate among the existing flows in ad hoc networks and support of quality of service (QoS) in such networks. In this research we are going to evaluate the performances of PA (the authors of this paper have proposed the PA algorithm) and QPART algorithms in different conditions. These two algorithms are able to support quality of service in ad hoc networks. It should be noted that we have used ns-2 simulator software to compare these two algorithms. (pp. 27-34)
