Investigating MAC Power Consumption in Wireless Sensor Network
Javier Bonny, Jun Luo · 2005
Because of the difficulty in recharging or replacing the battery of each node in a wireless sensor network, the energy efficiency of the system is a major issue. There are different ways to reduce energy consumption, one of them is to have a MAC protocol specifically designed for this goal. In this report, we first describe two proposed MAC protocols for sensor networks emphasizing their energy saving methods. Finally, we present our proposal, RTS Preamblingwhich further improve energy saving.
