ABSTRACT: The wireless sensor
network (WSN) is one of the budding exploring areas and fast rising fields in
wireless communications. The sensor nodes in the network are generally
small-size, low-cost, low-power and multi-function capabilities. Wireless
sensor networks (WSNs) are used for various applications; since numerous sensor
nodes are usually deployed on remote and inaccessible places, the employment
and preservation should be easy and scalable. Sensor nodes in the field being
run out of energy quickly has been an issue and many energy efficient routing
protocols have been proposed to solve this problem and preserve the long life
of the network. This paper work proposes a hierarchical based node activation
routing technique which shows energy efficiency. This technique selects cluster
head with highest residual energy in each communication round of transmission
to the base station from the cluster heads. Hierarchical based node activation
routing technique with different levels of hierarchy simulation results
prolongs the lifetime of the network compared to other clustering schemes and
communication rounds of simulation increase significantly.
