Statistical method of group mobile nodes in wireless sensor network

The invention discloses a reliable statistical method of group mobile nodes in a wireless sensor network. The method comprises the following steps of: constructing a cluster by using a probability-based method and selecting a cluster head node; and assembling the information of a plurality of nodes into one or more message packets and sending to a beacon node by the cluster head node so that the conflict interference to message transmission is lessened. Through sensing, retransmission and redundancy mechanisms, the reliability of the statistical method is improved, the real-time and reliable statistics of the node information is realized, and thus, an effective statistical method is provided for the group mobile nodes in the wireless sensor network.
