Network densification with small cells has been recognized as the key mechanism in addressing the unremitting traffic growth over the next decade. This hierarchical network paradigm is characterized by highly fluctuating traffic demand, vast amount of signaling exchange, as well as progressively intensified resource under-utilization owing to service asymmetry. A flexible backhaul framework is imperative...
Rapid growing demand for mobile traffic and severe service bursts generated by various mobile applications are challenging the capacities and management of future cellular networks. The measurement data from real cellular networks indicate that the mobile Internet traffic expresses long-range dependence (LRD) characteristics, which differs from the traditional exponential assumption as well as 3GPP...
