Abstract :
This paper analyzes two handoff stream management algorithms suitable for mobile cellular networks. In order to obtain a high total admitted traffic while guaranteeing the protection of handoff stream, handoff calls (HC) and originating calls (OC) are both queued. The strategies, named buffer rigid partitioning (BRP) and push out of OC (POC), are studied for different percentages of HC, selected according to the radius of the cells. Numeric computations aiming at estimating the optimum buffer size have been carried out. The results are obtained by an exact analytical model for the BPR scheme and by means of simulations for the POC scheme. The performance achieved with BRP and POC schemes is superior with respect to classic schemes based only on queueing of HC
