|Abstract:||This paper presents a new dynamic and adaptive bandwidth allocation scheme to prevent handoff failure due to lack of resources in mobile cellular networks, known as the Measurement-based Pre-assignment (MPr) technique. This technique is particularly useful in micro/pico cellular networks which offers Quality of Service (QoS) guarantee against call dropping. The proposed MPr scheme distinguishes itself from the well-known Guarded Channel based schemes in that it allows the handoff calls to utilize a pre-reserved channel pool before competing for the shared channels with new call arrivals. The key advantage of the proposed MPr scheme is that it can easily derive the number of channels that needs to be reserved for handoff based on a pre-determined call dropping probability, without the need for solving the often complex Markov chain required in Guarded Channel schemes, thus making the proposed MPr scheme simple and efficient for implementation. In addition, the MPr scheme is dynamical in that it can adjust the number of reserved channels for the handoff according to the traffic changes in the system.|
