Abstract:

A critical issue in mobile picocellular network configurations at 60 GHz is the inefficiency of classical handoff process due to restrictions derived by the small cells' topology, which leads to very frequent handoffs as well as by the limited overlapping areas between adjacent cells. In this paper we focus on Radio-over-Fiber (RoF) network architectures at 60 GHz band, which recently attracts high attention for delivering broadband wireless access services. We introduce a Markov chain model that depicts the behavior of the dominant handoff algorithms in such topologies and calculates cell blocking probability and cell utilization. Furthermore, we improve the efficiency of handoff algorithms by extending the model with Call Admission Control (CAC) policies. The results of the proposed models are presented and verify that the combination of CAC policies with handoff schemes increases the desired performance.
