Performance evaluation of battery-life-aware routing schemes for wireless ad hoc networks

Advances in battery technology have fallen behind that of CPU technology. Since each node in an ad hoc wireless network operates on batteries, power consumption becomes an important factor. To maximize the lifetime of ad hoc wireless networks, the power consumption rate of each mobile host must be evenly distributed. Also, the overall transmission power for each connection request must be minimized. These two objectives, however, cannot be satisfied concurrently with existing ad hoc routing algorithms. Hence, we present a new power-aware routing scheme to satisfy these two constraints simultaneously. Simulation results reveal that our proposed scheme outperforms others.
