Abstract
In this paper, we propose new methods to reduce the handoff blocking probability in next generation wireless networks. This reduction is based on an adaptive resource reservation scheme that provides quality of service (QoS) guarantees, and handoff priority in admission and in scheduling. To this purpose, the proposed schemes employ received signal strength (RSS) and speed to reserve available resources for a user from its adjacent cells according to its current position. The performances of the proposed schemes are compared with others methods by simulation. Our new scheme reduces not only the handoff blocking probability, but also maintains a low new call blocking probability.
