Lifetime extension based on residual energy for receiver-driven multi-hop wireless network

For sensor networks, the extension of operating time by controlling power consumption is an important research subject. In a receiver-driven communication protocol, a receiver node transmits its ID to the sender node periodically, and in response the sender node sends an acknowledgment. The average power consumption of the network can be controlled, but a part of the network shuts down when the battery of the node that consumes the most power is completely discharged. To extend the network life time, we propose a method where information on residual energy is exchanged through ID packets in order to balance power consumption. We show that the network life time can be extended by about 75% while maintaining network performance such as the packet collection ratio and delay.
