我们将无线自组织网络的尺度规律的分析扩展到实际移动过程中常见的相关节点运动的情况。我们考虑了参考点群移动模型的一个简单版本，其中属于同一组的节点被约束在一个圆盘区域内，该圆盘区域的中心根据i.i.d模型在网络上均匀移动。我们假设快速移动条件，并以每节点吞吐量最大化为主要目标。我们发现，相关节点运动对渐近吞吐量和延迟有巨大的影响，并且有时会比独立节点运动产生更好的性能。
We extend the analysis of the scaling laws of wireless ad hoc networks to the case of correlated nodes movements, which are commonly found in real mobility processes. We consider a simple version of the Reference Point Group Mobility model, in which nodes belonging to the same group are constrained to lie in a disc area, whose center moves uniformly across the network according to the i.i.d. model. We assume fast mobility conditions, and take as primary goal the maximization of per-node throughput. We discover that correlated node movements have huge impact on asymptotic throughput and delay, and can sometimes lead to better performance than the one achievable under independent nodes movements.
