Adaptive resource management in mobile wireless cellular networks

Abstract

Emerging mobile wireless networks are characterized by significant uncertainties in mobile user population and system resource state. Such networks require adaptive resource management that continuously monitor the system and dynamically adjust resource allocations, such as the number of guard channels reserved for handoff calls, for efficient system performance. The main objective of this research is to manage resource such a way so that it can maintain the target call dropping probability as well as utilize the scarce wireless resource efficiently. We propose a simple adaptive resource management scheme which is event based to adjust the number of guard channels for maintaining target call dropping probability. We try to evaluate the performance of the proposed scheme using extensive discrete event simulation. The results indicate that the scheme can guarantee the target call dropping probability under a variety of traffic conditions, and so can utilize the scarce wireless resource efficiently. © Springer-Verlag 2004.
