To accomplish a high throughput in problematic wireless connections, Opportunistic Routing (OR) team up all the sensor nodes in the way while sending the data packets. In this paper, Energy Efficient Mid position Opportunistic Routing (EEMOR) has been proposed for energy efficient multi-hop communication between a source and destination pair in WSN. The source node selects the mid position node with high residual energy node as a forwarder node to transmits the packet to the destination. The proposed algorithm is implemented and evaluated. The simulation results show that the proposed algorithm performs superior to the other existing algorithms in terms of end-to-end delay, energy consumption and network lifetime.
