Modeling Prioritized Hard Handoff Management Scheme for Wireless Mobile Networks

The channel associated with the current connection serviced by a base station is changed while a call is in progress. Usually, continuous service is achieved by supporting handoff from one cell to another. It is often initiated either by crossing a cell boundary or by deterioration in quality of the signal in the current channel. The existing call is then changed to a new base station . For the traffics which are non stationary at and are away from the servicing base station , the chances of a call to be handed off are increasing. In this paper we propose a scheme S MH 2 to modeling and implementing a traffic el mod with handoff behavior for wireless mobile networks . The simulation model S MH 2 with priority is developed to investigate the performance behavior of hard handoff strategy. Novelty of the proposed model S MH 2 results that it can improve call blocking rate of handoff calls . In addition to this, measurement of blocking probabilities for both g originatin calls and handoff calls is another impressive achievement of the model.
