Low Power, Low Delay: Opportunistic Routing meets Duty Cycling [PDF]
, 2012 Traditionally, routing in wireless sensor networks consists of two steps: First, the routing protocol selects a next hop, and, second, the MAC protocol waits for the intended destination to wake up and receive the data. This design makes it difficult

Vehicle-cycle and life-cycle analysis of medium-duty and heavy-duty trucks in the United States
Science of The Total Environment, 2023 Medium- and heavy-duty vehicles account for a substantial portion (25 %) of transport-related greenhouse gas (GHG) emissions in the United States. Efforts to reduce these emissions focus primarily on diesel hybrids, hydrogen fuel cells, and battery electric vehicles.
