Minimizing energy consumption in sensor networks using a wakeup radio

摘要: For increasing the life of sensor networks, each node must conserve energy as much possible. In this paper, we propose a protocol in which is conserved by amortizing cost communication over multiple packets. addition, allow sensors to control amount buffered packets since storage space limited. To achieve this, two-radio architecture used allows "wakeup" neighbor with busy tone and send its for that destination. However, process expensive because all neighbors awake listen primary channel determine who intended Therefore, triggered wakeups on are proposed avoid using more costly wakeup procedure. We present efficiently determining how large period these should be such consumption minimized.
