In this paper, ARMM (adaptive-bandwidth reservation mechanism using MPP) is proposed to provide the consistent QoS guarantees for multimedia traffic in a mobile computing environment. Each cell can reserve fractional bandwidths for hand-off calls to its adjacent cells, and this aggregated reservation of bandwidth can only be used for hand-off calls and not for new calls. It is important to determine the right amount of reserved bandwidth for hand-off calls, because the blocking probability of new calls would increase if we reserve more bandwidth than being necessary. This paper proposes an algorithm based on a MPP (mobility pattern profile) and a 2-tier cell structure to determine the amount of bandwidth to be reserved in the cell and to dynamically control its amount based on its network condition.
