Optimal probing control for wireless transmission when the payload is negligible
Abstract
A mobile electronic device needs to periodically connect to a stationary receiver, but the information to
transfer is minimal. One such example is the electronic bracelet used in house arrest, where the main
purpose is to inform the receiver that the person is in the house. Because the mobile device does not
know its current distance from the receiver, it has incentive to first send a low-strength signal to conserve
its battery energy. If the low-strength signal fails to reach the receiver, the mobile device then gradually
increases its signal strength until a successful connection occurs. By formulating the problem as a dynamic
program, we characterize the structure of the optimal probing policy and develop an algorithm to compute
it. We also consider a discrete approximation that can be easily implemented in practice. Numerical
examples show promising improvement of the derived policy over naive heuristic policies, and that the
derived policy is robust when there are small errors in estimating the distribution of the distance between
the mobile device and the receiver.
