An Optimal Call Admission and Bandwidth Reservation Scheme for Future Wireless Networks
The next generation wireless networks promises availability of a wide variety of services. To be supported successfully, it is necessary to provide quality of service (QoS) between end-systems with the resources whose cost is discouragingly high. This paper proposes a new scheme for call admission and bandwidth reservation for the next generation wireless networks. The proposed scheme OPBR (optimal cell partition based bandwidth reservation) does an optimal partitioning of the cell to give high degree of call admission and successful handoff. In addition it offers effective bandwidth utilization and guarantee QoS. The performance of the scheme is done by analytical modeling and simulation experiments. A comparison with two different schemes (PBR and adaptive reservation) shows desirable results can be achieved by proposed scheme with better performance for various QoS parameters.
