WSNs heterogeneous cluster routing based on distributed fuzzy logic inference

摘要

In this paper, the wireless sensor network of heterogeneous non-uniform distribution is studied, and sun energy harvesting model ISHE based on intensity of illumination is proposed. In ISHE model, the light intensity sensor is used to read solar illuminance under the current environment, and then, energy size obtained by solar energy supply node at specified period can be estimated based on corresponding relation between illuminance and irradiance. The experiment results show that invalidation round rate of the first node LEACH in the algorithm proposed in the paper is 86.2% higher than the average value and invalidation round rate of the last node is 65.9% higher than the average value; network coverage rate of the algorithm in 86% of lifetime is 38% higher than LEACH; network throughput of the algorithm proposed in the thesis at round 2,000 is five times as that of LEACH.
