Abstract

Wireless Sensor Network (WSNs) is used broadly for collecting data and the data
is used in performing tasks which are mission critical. The most inspiring thing in Sensor
Networks deployed in mission critical jobs is the implementation of routing protocols
which is energy effectual. We put forward an enhanced and stable energy effectual routing
protocol for heterogeneous WSNs in this paper. The key factors analyzed for improving
efficacy of routing are consumption of energy during communication in clusters and varied
levels of energy in heterogeneous WSNs. In this proposed routing protocol, the probability
of a node becoming cluster head (CH) is on the basis of the rate of energy consumption
and the transmission area covered by the node. Apart from these, we incorporate node
heterogeneity with respect to initial energy and we observe the impact in the network performance.
Our results obtained from simulation confirms the fact that the proposed method
can prolong the network lifespan compared to existing protocols used in homogenous
WSNs, which is essential for applications which are mission critical.
