在中继节点固定的确定性网络中，联合中继选择是一种有效的中继选择方案，能够以较低的系统复杂度获得接近最优的中断性能。然而，只有在固定的拓扑设置下才能验证组合继电保护选择的效率。为了研究空间随机网络(SRN)中联合中继选择的性能，我们使用泊松过程对协作网络的动态特性进行建模，并研究了该系统的中断性能。令人惊讶的是，确定性网络中出现的组合中继选择的等价性原则在SRN中并不成立。
In deterministic networks where relay nodes are stationary, combined relay selection is an efficient relay selection scheme, which is capable of achieving the near-optimal outage performance with much lower system complexity. However, the efficiency of combined relay selection is only validated upon fixed topological settings. To investigate the performance of combined relay selection in spatially random networks (SRNs), we employ the Poisson point process to model the dynamical nature of cooperative networks and study the outage performance of the proposed system. It is surprising that the equivalence principle of combined relay selection appearing in deterministic networks does not hold in SRNs.
