Improved LEACH algorithm for smart home controller

摘要

An improved LEACH algorithm was proposed for the fading feature in the smart home indoor wireless sensor node channel transmission. The algorithm allocated Area ID number according to the location of the nodes, selected the cluster head combined with the remaining energy of the nodes, and realized the partition clusters. The practicability of the simulation result was assured with the energy consumption model of the loss model for three-order polynomial logarithm distance path. The reliability of data transmission was assured through transmitting the data from different channels with TD-FDMA technology according to the Area ID number of the nodes. Matlab was used for the performance analysis of algorithm, and the simulation result showed that when compared with LEACH, the death time of the nodes was more concentrated, which can balance the energy consumption of the network nodes. The time for the appearance of monitoring blind spots was short. The network life cycle was extended, and the sensor node was more economical and efficient.
