[求助] 文中一段求助翻译（计算机网络无线传感器网络）

看得文章中有几句话看不懂，求助：
The mobility factor is the cumulative sum of the weight values of all intermediate nodes that form the path.This approach requires the modification of the routing table so that it contains the mobility factor for the paths.
另外，还有一句：
Figure 5 shows the number of control overhead bytes needed to achieve the packet delivery. The control overhead of AODV is more significant when the mobility of the nodes increases. Due to its frequent messages, MAER usually generated more control traffic than AODV when the maximum speed equaled or exceeded 10 m/s. The control overhead of MAER did not scale linearly with high mobility.

移动性因子是由累计形成路径所有中间节点的权重值得到的。这种方法要求修改路径表以便含有路径的移动性因子。

Figure 5 shows the number of control overhead bytes needed to achieve the packet delivery. The control overhead of AODV is more significant when the mobility of the nodes increases. Due to its frequent messages, MAER usually generated more control traffic than AODV when the maximum speed equaled or exceeded 10 m/s. The control overhead of MAER did not scale linearly with high mobility.
图5显示要成功发送该包所需控制字节的数量。当节点移动性增加时，AODV所需的控制字节很显著。因为频繁的消息，在最大速度大于等于10m/s时，MAER通常比AODV产生更多的控制流量。MAER的控制消耗不随移动性增高线性增高。

overhead就是做件事必须付出的代价，类似成本。

To do great work, you have to have a pure mind.
