Hence, in order to avoid that some nodes become the bottleneck and to obtain high channel capacity, the channel capacity of each node should be equal.
Second, also the update of per-flow information must be fast, which suggests that fast memories are needed in order to avoid that memory access becomes the system bottleneck.
Meanwhile, in order to avoid too low D2D link throughput, which might become the throughput bottleneck of the entire transmission path, an estimation method of relay preselection is proposed in this paper to reduce the possibility of abandoning the preselected relays in the phase of relay verification.
In order to avoid potential bias due to local demographic events specific to certain populations, such as bottlenecks, directional selection or recent gene flow, we excluded some populations known for their small size and/or isolation, such as the Nu, Wa, Jinuo [ 34], or for their recent interbreeding history, such as the Uyghurs, Kinh and Thai [ 35].
They have largely avoided Tahrir in order to avoid precipitating any confrontation between civilians.
In order to avoid this, passive filters are prominently used.
