分布式网络中随机接入传送容量的研究

Analysis of the Random Access Transport Capacity in Distributed Networks

为解决分布式网络的容量研究局限于单跳网络容量的问题,提出了一种用于研究分布式网络中端到终端的随机接入传送容量的中继接收机选择策略,证明了数据经过有限跳数的中继后可以到达目的接收机处,在建立的网络模型基础上对随机接入传送容量进行了理论推导,得到了随机接入传送容量的理论表达式.数值分析和仿真结果表明:随机接入传送容量随着最大中断概率的增大而增大,随着传输距离的增加而增加.

To solve the problem that the study of the capacity in distributed networks was constrainted in the single hop case, a strategy of selecting relay was proposed to analyze the random access transport capacity in the distributed networks with multi-hop case, by using which the transmitted data would arrive at the final receiver within finite hops, and the expression for the random access transport capacity was derived. Numerical and simulation results showed that the random access transport capacity increased with the maximum probabili- ty of outage, and increased with the transmission distance.
