Abstract
Hierarchical macrocell and femtocell networks aim to provide seamless roaming and improve network capacity. UEs moving in such networks may experience frequent handovers. In this paper, a handover decision algorithm considering data arrival, handover delay and signaling cost is proposed based on Markov decision processes. The expected total reward seeks a balance between transmission latency and handover signaling overhead, under dynamic traffic arrivals. A typical scenario is simulated, where a UE roams in a macrocell, passing through an array of femtocells with different connection capacities, and the simulation experiment indicates the effectiveness of the proposed algorithm.Keywords
