Wireless sensor networks (WSN) are becoming an inevitable solution in industries for its automation and monitoring applications. Sensor nodes in WSN are deployed in fields with limited power. By nature these nodes are left unattended after deployment. This raises the importance of developing efficient algorithms which are capable of increasing the network lifetime by consuming less energy during the operations. This paper proposes a hybrid clustering energy aware routing protocol (H-CERP) for heterogeneous WSNs. H-CERP is designed to form efficient clusters with less cluster head count than the optimal estimation and uses multihop communication with gateway nodes to communicate with the base station. This novel approach makes our system more advantageous where the network lifetime and coverage of sensors are much vital at no additional cost. By deploying H-CERP in designed environment the results extracted shows promising results in terms of energy consumption, residual energy and lifetime of nodes when compared with generic methods like LEACH, PEGASIS and other recent techniques.
