  abstract = {Traditional approaches using superimposed signals in wireless sensor
	networks have high demands on the hardware capabilities of a single
	network node. This work loosens these constraints and derives a communication
	system for low-resource wireless sensor networks requiring no complex
	signal processing, no fast A/D conversion, no carrier or phase synchronization.
	Therefore, it is applicable for low-resource hardware like low- cost
	networks, RFID or even polymer electronics. It is based on a new
	modulation technique (ESK) which only uses the power of a signal
	for encoding and is implemented and evaluated on the pPart particle
	computer hardware. Various useful applications beyond the state of
	the art are presented and prove the concept of superimposed signals
	for wireless sensor networks. },
