Opportunistic routing is a wireless multi-hop routing approach that allows each packet to be relayed through any node that overhears the transmission. In this letter, we propose a method for avoiding duplicate forwarding in opportunistic routing. The proposed technique enables forwarding nodes to control relaying at their neighbors on a per-packet basis using a small amount of information piggybacked on packets. Our simulation results show that DFOR achieves higher throughput than existing relevant protocols by reducing unnecessary transmissions.
