Abstract :
This paper presents a distributed algorithm for enhancing the connection quality and bandwidth utilization in the cellular mobile network, which can improve the quality of service (QoS) in wireless cellular networks. This algorithm allows the history information of the mobile entity to be used to predict an elliptical shadow around it, which covers all spots that the mobile is going to move with a high possibility in a given time. The cells, and only the cells that overlap the shadow should reserve the resource for the mobile connection so as to achieve a low hand-off dropping rate and reduce remarkably the unnecessarily reserved resource. The algorithm is self-adaptive when the motion is very unpredictable, by observing the mobile actual movement and automatically adjusting the elliptical shadow Our simulation proved it to be effective in achieving satisfactory QoS parameters such as connection quality and bandwidth utilization
