双重约束下的海洋无线传感网自适应成簇算法
Adaptive Clustering Algorithm in Ocean Wireless Sensor Network Under Double Constraints
摘要
Abstract
Aiming at the problems that energy consumption is too fast and the network life shortens due to the high dynamic marine environment and other factors in Ocean Wireless Sensor Network(OWSN), an improved Low Energy Adaptive Clustering Hierarchy(LEACH)algorithm named LEACH-τ is proposed. In cluster head node selection, the improved algorithm not only takes into account the node residual energy value and the distance from the node to sink node, but two factors are considered in the selection of relay node τ which can communicate with sink node directly:the difference between residual energy of the cluster head and the average residual energy; the difference between distance of the cluster head node from the sink node and the average distance to select the relay node from the cluster head nodes. The computer simulation results show that the LEACH-τ algorithm is able to reduce the overall energy consumption and effectively extends the life cycle of the Ocean Wireless Sensor Network(OWSN)compared with the typical LEACH and IMHT-LEACH.关键词
