    abstract = {Due to heterogeneity in the power of nodes, asymmetric link is commonly encountered phenomena
in wireless sensor networks (WSN). Most of the routing protocols in WSN are proposed to work on
bidirectional links which render the use of asymmetric links infeasible. In this study, we propose LEERP: A layer
based energy efficient routing protocol for wireless heterogeneous sensor networks (WHSN) that makes use
of asymmetric link to provide better energy efficiency and higher delivery rate. The LEERP protocol first
identifies the asymmetric link and provides bidirectional for those links by reverse path algorithm. Then, it uses
level values and energy threshold value to select next forwarding nodes in the neighbor list of each node.
Simulation results show that our protocol significantly outperforms the other existing methods in WHSN.}
