Abstract (EN)Admission control plays an important role in providing the desired Quality of Service (QoS) in wireless networks. It depends on precise estimates of bandwidth available in the network and the bandwidth required by new flows. Estimating these parameters in wireless networks is challenging due to the shared and open nature of the wireless channel. Resources sharing in wireless links imposes a number of problems in a QoS enabled networks. One of the problems is the estimation of the performance of implied radio links. In this article, we present a novel admission control for infrastrure-less clustered wireless networks. The proposed admission control is based on QoS constraints and the lifetime duration of mobile nodes, including speed, power consumption and capacity parameters. Some new schemes are introduced, QoS parameters are negotiated during the admission procedure, and a forced handover technique is developed instead of reject flows using a centralized view of topology. We also propose algorithms that implement these approaches. The simulation results confirm the effectiveness of the admission control schemes.
