Base station sleep mode is an effective method to reduce the energy consumption of cellular networks. Taking into account a cellular network, its central base station (BS) can turn into sleep mode when the traffic is low and the users in this cell can access to neighbor active cells. A user offloading algorithm for the sleeping cell is investigated. The energy consumption of the cellular network in...
To meet the ever-growing demand for a higher communicating rate and better communication quality, more and more small cells are overlaid under the macro base station (MBS) tier, thus forming the heterogeneous networks. Small cells can ease the load pressure of MBS but lack of the guarantee of performance. On the other hand, cooperation draws more and more attention because of the great potential of...
Due to the extensive and continuously rising energy consumption in modern telecommunications networks, several approaches have been suggested to improve their energy efficiencies, that is network re‐engineering, dynamic adaptation of network or device resources, sleeping/standby approaches. But there are some limitations in these approaches. For example, in mobile networks, some approaches suggest...
It is of great importance for service providers to evaluate the impact of inter-cell co-channel interference on the outage probability in cellular networks. In this paper, the probability density function (PDF) of interference factors limited by power control scheme is derived. Moreover, a series-form outage probability affected by the interference from Poisson-Voronoi tessellation (PVT) cellular...
To improve the spectral efficiency in cognitive radio networks, it is essential for cognitive radio users to be equipped with intelligent learning capability. Many different learning methods have been applied in different kinds of cognitive radio network models. This study presents two novel learning algorithms that can be applied to cognitive radio network models based on IEEE802.22. One is a no-regret...
Continuously growing energy consumption in cellular networks motivates the research towards energy saving approaches. Among previous work, many studies suggest different base station shutdown strategies to reduce the transmission power in case of low or no traffic. Besides the strategy that shutdown base stations completely, our work suggests and evaluates the usage of partial shutdown strategy for...
