A network division model for wireless sensor networks
一个无线传感器网络的网络分割模型

The paper firstly pointed out that the net division can affect network connectivity and then the communication efficiency. Secondly, the communication factors that cause net division in wireless sensor networks were discussed from the perspective of the physical layer and MAC protocol. To quantitatively depict network division, the net division ratio was defined, and the physical and geometric factors that affect the net division ratio were analyzed. Based on massive data collected by trials, a net division model for WSNs was established by doing a series of curve family fitting. The model determined that net division ratio, number of nodes and area ratio obey the given mathematical relationship.
