Therefore, from the principles of human motion, this paper studies the mobility model of WBAN.
因此，本文从人体运动模型出发，结合人体运动规律，研究了无线体域网节点运动模型。
Since the body movement is quite different from other kinds of motion, dynamic topology changes of WBAN are also very different from other WSNs.
由于人体的运动有着不同于其他事物运动的规律，无线体域网的动态拓扑变化必然与其他无线传感器网络拓扑变化有很大不同。
In WBAN, human body which is considered as the carrier of all kinds of sensor nodes will influence the channel characteristic, and this makes the channel time varying.
在无线体域网环境中，人体作为各种传感器节点的承载体影响着整个网络中的信道特性，使得环境中的信道具有快速时变的特性。
Because of the human body movement, network topology of WBAN is highly inconstant. Thus, how to improve network connectivity and balance network energy consumption is another crucial issue of WBAN.
人体运动的特点决定了无线体域网网络拓扑易变，如何提高网络连通性、平衡网络能量消耗是WBAN设计中另外一个核心问题。
