协作多点传输对网络能效性能的影响

Effects of coordinated multi-point transmission on performance of network energy efficiency

为节省蜂窝网络中的能量并保证用户的服务质量,需要在能量消耗和延迟之间达到一个折中。采用M/G/1队列建模基站的睡眠模式,通过分析得到能量损耗和平均时延之间的关系,在此基础上,演示协作蜂窝网络的能耗函数;研究平均中断概率约束对网络能耗节省的影响,以降低网络能耗,在提高网络性能的前提下,有效控制传输时延。

To save the energy of the network and to guarantee the service quality of users, a tradeoff between the energy consumption and the delay needs to be reached. BS sleeping pattern was modeled with M/G/1 queue and the energy consumption function of cooperative cellular network was demonstrated by analyzing the relationship between the energy consumption and the average delay. Meanwhile, the effect of an average outage constraint to the energy consumption saving was studied to reduce the network energy consumption and to control the transmission delay effectively on the premise of improving the performance of the network.
