Improvement of LEACH Algorithm Based on Inter-Cluster Ring Routing Strategy ()
ABSTRACT
Wireless Sensor Network (Wireless Sensor Network,
WSN) is a self-organizing
network formed by a large number of wireless sensor
nodes through radio communication [1]. The
sensor nodes in the network cooperate with each other to monitor and collect
the object information in the observation area, and the information is
transmitted to the users who need this information after data fusion
processing. It is often deployed in harsh environments, such as oceans, deep forests, and deserts. At the
same time, the sensor nodes in the network are powered by batteries [2]. These
external factors make it impossible to replace batteries manually. Therefore,
energy is an important resource for wireless sensor networks [3]. In
this paper, aiming at the problems of LEACH inter-cluster communication, from
the perspective of energy saving, an improved strategy using inter-cluster ring
routing is proposed. This strategy first abstracts all sensor nodes into a ring
system model during the network topology formation stage. In the data transmission
stage, a ring transmission strategy is adopted, and nodes on the ring are used
to randomly and evenly undertake data transmission tasks, so the imbalance of
energy consumption of sensor nodes can be effectively reduced. Simulation
experiments show that this strategy can extend the network life cycle to a
certain extent.
