On Bandwidth Reservation Policies in Broadband Wireless Networks
Jelena Mišić, Tam Yik Bun · 2000
Adaptive admission control reserves bandwidth for handoff calls by distributing bandwidth reservation values for each call to the neighboring base stations. The series of bandwidth reservation values distributed after k -th handoff determines the bandwidth reservation policy. This paper analyzes relationship between bandwidth reservation policies and call level QoS when user mobility is changing. We define classes of non-aggressive and aggressive bandwidth reservation policies. We show that bounded call level QoS under heterogeneous user mobilities can be achieved only by using aggressive bandwidth reservation policies. Examples of non-aggressive and aggressive bandwidth reservation policies are shown.
