Performance analysis of a distributed queuing MAC protocol for Ad-Hoc networks with different mobility conditions

Abstract

This paper analyses the performance of the DQCA AD HOC MAC protocol for scenarios where the communication nodes have different mobility conditions, corresponding to different applications such as sensor networks, inter-vehicular and pedestrian applications. It has been demonstrated that under low mobility conditions, the protocol performance is near-optimum. This performance is slightly reduced due to the cluster setup time when the relative movement speed of the nodes is increased. The variability of this performance behaviour is described in detail. Anyway, the protocol efficiency is remarkably high in all situations and, as a consequence, the protocol could be feasible for a wide range of applications.
