In this report, we model the problem of cell selection in open-access femtocell networks as a decentralized restless multi-armed bandit (RMAB) with unknown dynamics and multiple players. This is a classic exploration/exploitation problem where each user is trying to learn the best channel to maximize its capacity and reduce its frequency of handover. Each channel is modeled as finite state Markov chain with a Markovian reward. To solve this problem, we refer to the decentralized Restless Upper Confidence Bound (RUCB) algorithm that achieves a logarithmic regret over time for MAB problem. Also, we extend this algorithm to handle dynamic environment by applying a change point detection test based on Page-Hinkley test (PHT). Simulation results show that
? our two proposals come very close to the performance of opportunistic method in terms of capacity, while fewer average number of handovers are required.
? the use of a change point test allows better performance in terms of capacity particularly in a dynamic environment. |
