Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] First introduce the definition of RSSI: the received signal strength indication, which is used to determine the link quality, the basis for distinguishing inner and outer nodes, and whether to increase the broadcast transmission strength.
[0023] TDMA: time-division multiple access time slot allocation method.
[0024] A fast clustering method for energy balance suitable for wireless sensor networks, comprising the following steps:
[0025] Step 1: The establishment of fast clustering topology structure is divided into inner area division and outer sub-area division. For the specific division method, refer to Figure 1 and figure 2 :
[0026] Step 1: The cluster head broadcasts the "members whose RSSI value is greater than K please answer" command;
[0027] Step 2: In Figure 1 (a), a8 is closer to A, and the RSSI value is larger, whic...
