We introduce TORP - TinyOS Opportunistic Routing Protocol for Wireless Sensor Networks (WSNs). The main motivation is that when a data packet is transmitted, the multiple relay nodes cooperatively select the one which is closest to the destination node to continue forwarding the data packet. TORP attempts to save energy versus traditional deterministic routing protocols by selecting the next forwarding node dynamically based on the results of the packet delivery to neighboring nodes. We present the details of TORP design to illustrate how to select the next forwarding nodes by avoiding duplicate packet transmissions. Utilizing TelosB motes, we compare the performance of TORP against the Collection Tree Protocol. We present the performance results and the in-depth analysis in terms of throughput, hops per transmission, and power consumption.
