Abstract

This poster presents a hardware/software solution, called On-The-Go Switch (OTGS), enabling a smartphone to control the connection state of a USB-attached device. Through an example, we show how OTGS can reduce the energy consumption of portable spectrum sensing platform utilizing lowcost Software Defined Radio. We show that OTGS can reduce the energy consumption by 47%, compared to a baseline, which would be difficult with a software alone, e.g. kernel modification.
