Bounding the Mobility/Capacity Conversion Efficiency in Multi-Service Wireless Communications Networks

In this paper, the mobility/capacity conversion (MCC) efficiency of reuse-based resource management strategies in multi-service wireless communication networks is mathematically analyzed. In particular, a useful and efficient resource management strategy is proposed and evaluated. The proposed strategy exploits the synergy between the maximum packing, multiple fractional channel reservation, and anticipated channel release mechanisms to maximize the MCC efficiency achieved by reuse-based resource management strategies in multi-service wireless communication networks. In order to capture the inter-cell dependency, which is required to study the MCC process, a multi-cell model is considered for the teletraffic analysis. The effect of the relative users´ mobility and bandwidths requirements on system capacity is evaluated. Numerical results show that the use of dynamic channel allocation and handoff protection policies, in addition to the anticipated channel release mechanism, in the resource management strategy is crucial for minimizing the impact of mobility on the MCC process. This is especially true when the network supports multiple classes of subscribers having different bandwidth and quality of service requirements.
