多跳蜂窝网络中小区间干扰变化及对多小区网络性能的影响

Inter-cell Interference in Multi-Hop Cellular Networks and the Impact on Performance of Multi-cell Networks

对蜂窝网络中加入多跳模式后小区间干扰的变化进行了分析,通过分析和仿真给出了不同的无线传输环境下和不同的多跳模式配置(路径损耗、多跳平均跳距、多跳区域内环半径)多跳模式对小区间干扰的降低比例;根据分析结果给出了多跳模式下网络整体性能提高需要的场景和系统配置,使通过多跳模式提高多小区网络系统性能成为可能。

This paper analyzes the inter-cell interference when multiple-hop mode is added in the cellular networks. Simulation and analysis is done to show the impact of different system parameters and wireless channel characters, such as path loss and multi-hop distance and inner-radius of multi-hop area, to inter-cell interference in multi-hop cellular networks. According to these simulation and analysis results, we provide the scenario and system configuration to increase system throughput, which can improve multi-cell networks performance.
