Sensor Network (WSN) consists of spatially distributed and dedicated sovereign
sensor nodes with confined resources to politely monitor physical and
environmental conditions. In recent years, there has been a rising interest in
WSN. One of the major confrontations in WSN is developing an energy-efficient
routing protocol to enhance the network longevity. With that concern,
this work contributes in providing a novel approach called DAO-LEACH (Data
Aggregation based Optimal- LEACH) by which the energy efficient routing in WSN
is attained based on effective data ensemble and optimal clustering.
Aggregating the data sent by cluster members comprehend in draining network
load and amending the bandwidth. In order to minimize the energy
dissipation of sensor nodes and optimize the resource utilization, cluster head
is elected for each cluster. Moreover, the energy efficient route in WSN is
obtained by combining the nodes having maximum residual energy. Experimental
results have shown that the proposed approach furnishes efficient route for
data transmission among the sensor nodes in an adept manner, thereby prolonging
the network lifetime.
