Abstract
This paper focuses its attention on the rate adaptation problem in wireless network with mobile hosts. We define two new quality of service (QoS) indexes. They express the degradation degree of bandwidth and the frequency of bandwidth degradation suffered by data packet flows. These indexes are used to define and propose a new rate adaptation algorithm named degradation degree based fair algorithm (DDFA). The aim of the proposed algorithm is to fairly distribute the effects of QoS degradation among the cell visited by the mobile hosts. The DDFA algorithm has been compared with a fair adaptation algorithm proposed in the literature. The performance evaluation shows that proposed algorithm reduces the QoS degradation of flows without adding control overhead compared to the reference fair algorithm.
