Abstract:

This paper addresses the case of hierarchical cellular network environment where both macrocell and femtocell are deployed to improve network capacity. The accepted service access to the femtocell is classified into four categories based on the timing relationship between its packet arrival/departure and mobility. An analytical framework is developed for admission control based on partially observable Markov decision process. The admission control decision scheme takes into account both bandwidth resource occupancy time and signaling cost. Simulation experiments corroborate the effectiveness of the developed algorithm.

Key words: admission control, femtocell, hierarchical wireless network, partially observable Markov decision process
