“…The DPQ algorithm [13]- [14] avoids the major drawback of MBPS by giving high priority to a fast-moving MS. DPQ-like algorithms are widely recommended, but they only address the problem of the priority of a moving handoff call. When a system is a hot-spot, or a handoff call is stationary, DPQ cannot prevent high new call blocking ratios.…”

“…Several methods have been implemented on handoff management. For example, first come, first served (FCFS) queuing handoff scheme [6], measurement-base prioritization scheme (MBPS), hierarchical call admission control [11] [12] system and dynamic priority queuing of handoff calls scheme (DPQ) [13]- [15]. However, DPQ only addresses the priority of fast movement handoff calls.…”

Handoff management is an important issue in mobile communications networks. The multi-carrier code divide multiple access (MC-CDMA) technique is currently recommended, since it significantly increases the total throughput of a network system. This work presents a novel queuing system to resolve the problem in which the handoff call dropping ratio and new call blocking ratio are higher in a mobile communications network using MC-CDMA. An efficient queuing priority algorithm (EQPA) method that adopts a back and front handoff queuing module improve the handoff procedure. Priorities are set for different traffic types. Each handoff call handles its own priority ordering. Analysis of the proposed algorithm and comparison with existing methods by simulation demonstrates that the performance of EQPA is better than that of others. EQPA clearly increases system user's throughput, and decreases handoff call dropping ratio and the new call blocking ratio.
