Abstract

We propose HERAH(Hierarchical Energy-Aware Routing Algorithm for Heterogeneous Wireless Sensor Networks) that is the hierarchical routing algorithm in WSNs and is established on heterogeneous environment. HERAH performs CH selection by considering residual energy level and uses multi-hop communication within cluster. So, HERAH makes improvements in the energy savings and the network lifetime compared with LEACH.
