Assessment of DSACC and QPART Algorithms in Ad Hoc Networks


The rapid advancement in wireless over wired has augmented the need for improving the
Quality of Service (QoS) over such wireless links. However, the wireless ad hoc networks
have too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,
support of quality of service in ad hoc networks is the topical issue among the network
science researchers. In this research we are going to evaluate the performances of DSACC
(Distributed Scheduling algorithm with Collision Control) and QPART (QoS protocol for Ad
hoc Real Time Traffic) 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.
