Data packet transmission method and device based on wireless sensor network

The invention discloses a data packet transmission method and device based on a wireless sensor network. The method comprises the following steps: constructing a global view of the wireless sensor network; determining a source node according to the global view; determining a first pseudo source node according to the global view and the source node; according to the global view, forwarding the false data packet from the first pseudo source node to the sink node to obtain first pseudo transmission information; the false data packet is used for interfering the tracking of the source node; according to the global view and the first pseudo transmission information, forwarding the real data packet from the source node to the sink node to obtain real transmission information; the real transmission information is used for indicating to terminate forwarding of the false data packet. Therefore, the method is beneficial to delaying the process of discovering a real path by a destructor and prolonging the network securit
