基于随机几何理论对分布式网络进行了建模,研究了分布式网络中的两种不同功率控制策略对进度密度的影响,从理论上推导了信道反转功率控制策略和无功率控制策略时的进度密度表达式.数值分析和仿真结果表明:信道反转功率控制策略时的进度密度要比无功率控制策略时的进度密度要大,但是由于两种功率控制策略都没有考虑到干扰功率的影响,局限于对信号本身功率的控制,所以进度密度在两种不同功率控制策略时的区别不大.
Based on the theory of the stochastic geometry, the network model for the distributed networks was given. The effect on the density of progress for the distributed networks with two different power control strategies was studied, and the expressions of the density of progress with channel inversion power control strategy and no power con- trol strategy were derived. Numerical and simulation results showed that, the density of progress with channel inversion power control strategy was more than that with no power control strategy, but the difference between them was very small because these two power control strategies were limited to control of the power of the signal itself without consider- ing the influence of interference power.
