The applications of wireless sensor networks comprise a wide variety of scenarios. In most of them, the network is composed of a significant number of nodes deployed in an extensive area in which not all nodes are directly connected. Then, the data exchange is supported by multihop communications. Routing protocols are in charge of discovering and maintaining the routes in the network. However, the appropriateness of a particular routing protocol mainly depends on the capabilities of the nodes and on the application requirements. This paper presents an Energy-efficient expected transmission count technique in WSNs, and a Route Optimization Technique (ROT) using expected transmission metric count in clustered WSNs among obstacles. ROT forms an energy-efficient path between the CHs and other members in clusters and CHs to the sink
