A code update data delivery method based on energy recognition for wireless sensor network is provided to reduce transmission delay, redundant transmission, and data collision when transferring data to thousands nodes arranged in the natural environment. It determines whether to receive an advertisement message(S4). An advertisement message is broadcasted to nodes close to code data(S6). A code update data demand message is received(S7). It determines whether the advertisement message is idle state(S8). The idle state time is out(S9). It determines whether a code update data is a transmission/receiving mode(S10). |
