Abstract

Channel reservation techniques have been extensively used in cellular networks in order to meet the Quality, of Service (QoS) requirements. In this paper an influence-based channel reservation and call admission control scheme is proposed to provide the QoS guarantee in a mobile wireless network. The basic idea behind the proposed scheme is that a moving user, in addition to its requirements in the current cell, exerts some influence on the channel allocation in neighboring cells. Such an influence is related to the moving pattern of this user (speed and direction), and it can be calculated statistically. In this paper we first introduce the concept of influence curve, which provides an estimate of the requirements that the ongoing calls in current cell will impose on a neighboring cell. Based on this concept we propose a channel reservation scheme that dynamically and adaptively adjusts the number of channels that should be reserved for handoff purposes in each cell. The proposed algorithm can be carrie d out in a distributed way: each cell collects its current traffic condition, calculates the influence and sends the results to all its neighbors periodically. The performance evaluation of the proposed scheme is achieved via analysis and simulation.
