Abstract

The increasing use of wireless networks and the popularity of multimedia applications, leads to the need of QoS (Quality of Service) support in a mobile IP-based environment. This paper presents the framework, needed to support both micromobility and resource reservations. We present an admission control mechanism in which a mobile host can trigger reservations without performing handoff, taking advantage of link state changes caused by the handoff of other mobile hosts. We also investigate the impact of inaccurate link state information and the occurrence of simultaneous handoffs on the performance of the handoff and reservation mechanism. This impact is higher when only a small part of the mobile hosts can receive QoS service at the same time. For the simulations, we use Q-MEHROM [10]. Herein, [11] gathers the link state information and calculates the QoS tables. However, the ideas and results presented in this paper are not restricted to these protocols.
