  Abstract

The mobility prediction algorithm and the channel reservation scheme have been reported as an effective means to provide QoS quarantees and the efficient resource reservation in wireless networks. Among these prediction algorithms, the recently proposed Detailed-ZMHB algorithms makes use of the history of the user''s positions withih the current cell to predict the next cell, which provices the better prediction accuracu than the others. The handoff prioritizing schemes are proposed to provide improved performance at the expense of an increase in the blocking probability of new calls. In the soft handpff the CDMA system, a mobile can communicate via two adjacent cells simultaneously for a while before the actual handoff takes place. In this paper, we propose a new channel reservation scheme making use of the user mobility pattern information in order to reduce the call dropping probability. Our result show that the proposed scheme gives about 67.5-71.1% lower call dropping probaility, compared to the existing scheme.
