Real Entropy Can Also Predict Daily Voice Traffic for Wireless Network Users
Sihai Zhang, Junyao Guo, Tian Lan +2
Voice traffic prediction is significant for network deployment optimization thus to improve the network efficiency. The real entropy based theorectical bound and corresponding pred…
A Stochastic Geometry Approach to Energy Efficiency in Relay-Assisted Cellular Networks
Na Deng, Sihai Zhang, Wuyang Zhou +1
Though cooperative relaying is believed to be a promising technology to improve the energy efficiency of cellular networks, the relays' static power consumption might worsen the en…
Traffic-Aware Relay Sleep Control to Improve Energy Efficiency in Joint Macro-Relay Networks
Na Deng, Ming Zhao, Sihai Zhang +1
In this letter, we consider a joint macro-relay network with densely deployed relay stations (RSs) and dynamically varied traffic load measured by the number of users. An energy-ef…
Combined Channel Aggregation and Fragmentation Strategy in Cognitive Radio Networks
Lei Li, Sihai Zhang, Kaiwei Wang +1
In cognitive radio networks, channel aggregation (CA) and channel fragmentation (CF) techniques have been proposed to enhance the spectrum utilization. While most of the literature…
