Energy is the most limiting factor for remote outdoor deployments of Wireless Sensor Networks (WSNs). This paper proposes a novel routing algorithm for dual-platform nodes targeting WSN applications as found in smart farming applications. For scenarios in which high power components of nodes and radio links will be switched on at known points in time, our algorithm tries to make use of scheduled uptimes of nodes with the possibilities to turn other nodes on to send the nodes' data to a sink on time. We compare our method with a traditional flooding-based algorithm as well as with a greedy version which tries to transfer the data immediately. We show that our mechanism works energy-efficient while meeting all deadlines and keeping the amount of control traffic at a necessary minimum.
