Reception energy

Definition

Reception energy refers to the amount of energy consumed by a wireless sensor when it receives data packets from other nodes or devices within a network. This concept is crucial for understanding the energy consumption models used in wireless sensor networks, as it directly impacts the overall energy efficiency and battery life of the sensors, which are often deployed in remote or hard-to-reach areas.
