Energy-Harvesting Wireless Sensor Networks (EH-WSNs) [PDF]
ACM Transactions on Sensor Networks, 2018 Wireless Sensor Networks (WSNs) are crucial in supporting continuous environmental monitoring, where sensor nodes are deployed and must remain operational to collect and transfer data from the environment to a base-station. However, sensor nodes have limited energy in their primary power storage unit, and this energy may be quickly drained if the ...

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
