Design of an Energy Aware Cluster-Based Routing Scheme to Minimize Energy Consumption in Wireless Sensor Networks

Efficient usage of sensor nodes has fascinated researchers and scientists so that energy depletion of network can be decreased. Heterogeneous protocols are considered of paramount significance for fulfilling this purpose. Typically, energy of two or three levels of nodes are considered in heterogeneous protocols. But in real life, due to manufacturing variations, diversity in morphological factors and uneven physical terrain of sensor nodes, a broad range of energy levels exist. We propose an improved energy aware cluster-based routing mechanism to minimize energy consumption in wireless sensor networks (in short IEACRP). Through proposed mechanism, the lifetime, stability and throughput of network can be enhanced. Here, WSN contains sensor nodes with four energy levels, and some of the sensor nodes are kept into sleep mode if they have energy less than threshold. Sleep awake mechanism works as energy hole removing mechanism. Simulation results show that proposed mechanism attains longer stability, lifetime and throughput in comparison of EEAHP, TEEN, MODLEACH, DEEC, LEACH, E-MODLEACH and SEP.

Automated summary

Efficient usage of sensor nodes for minimizing energy consumption in wireless sensor networks using an improved energy aware cluster-based routing mechanism (IEACRP) enhances network stability, lifetime, and throughput.
