为研究不同功率控制策略对Ad Hoc网络传输容量的影响,把基于信干比(SIR)的功率控制(SBPC)策略应用到Ad Hoc网络中,使用随机几何理论对Ad Hoc网络进行建模,得到传输中断概率和传输容量的表达式.数值分析和仿真结果表明,相对于现有功率控制策略,基于SIR的功率控制策略能大幅度降低网络的传输中断概率,提高传输容量.
To study the transmission capacity for Ad Hoc networks with different power control strategies,signal-to-interference ratio(SIR) based power control(SBPC) is applied in Ad Hoc networks.By using stochastic geometry,a new model is introduced,and an expressions to outage probability and transmission capacity are derived.Simulation shows that,compared with the power control strategy used before,using SIR based power control can greatly decreases the outage probability,but increases the transmission capacity.
