Network clustering method of wireless sensor based on fixed cluster heads

Abstract

The invention discloses a network clustering method of a wireless sensor based on fixed cluster heads, suitable to a network topological structure of a hierarchical wireless sensor. In the method, nodes with relatively larger energy are used as fixed cluster heads to form a static cluster, and a method for establishing an intra-cluster data forwarding path is provided for solving the problem of long span from a first node death time to a last node death time. Under the condition of the same network energy consumption, in compression with an LEACH algorithm, the method can greatly improve the utilization efficiency of network energy and effectively reduce the mean energy consumption of the network in every round without adding any hardware equipment, and thus the method has popularization and application values.
