Method and device for transmitting data for wireless sensor network based on IP

The invention relates to a method and a device for transmitting data for wireless sensor network based on IP. The embodiment divides the devices in the wireless sensor network into different virtual special sensor networks based on logic and identifies the networks by virtual special sensor network identifiers for realizing network virtualization. The embodiment provides a method for transmitting data for wireless sensor network based on IP, which comprises the following steps of: receiving data grouping; the data grouping comprises virtual special sensor network identifiers related with the device and target address in the short address form of the virtual special sensor network; restoring the target IP address based on the virtual special sensor network identifiers and the target address in the short address form of the virtual special sensor network from the received data grouping; and confirming whether the target address is matched with the current address and operating based on the confirmed result. The method can share the physical wireless sensor network by lower communicating expense, and reduce the setting and operating cost of wireless sensor network service suppliers and the wireless sensor network operators.
