Cooperative diversity has been recently proposed as a way to form virtual antenna arrays
that provide dramatic gains in slow fading wireless environments. However, most of the …

This paper studies both limited sensitivity and nonlinearity of far field RF energy harvesting
observed in reality and quantifies their effect, attempting to fill a major hole in the …

We propose a simple distributed method to find out the "best" end-to-end path between
source and destination, among M possible relays. The method requires no explicit …

Scatter radio achieves communication by reflection and requires low-cost and low-power
RF front-ends. However, its use in wireless sensor networks (WSNs) is limited, since …

Sensor collision (interference) is studied in a large network of low bit-rate sensors that
communicate via backscatter, ie modulate the reflection of a common carrier transmitted by a …

This work presents an efficient and high-sensitivity radio frequency (RF) energy harvesting
supply. The harvester consists of a single-series circuit with one double diode on a low-cost, …

In this paper, we present simple opportunistic relaying with decode-and-forward (DaF) and
amplify-and-forward (AaF) strategies under an aggregate power constraint. In particular, we …

This paper studies tag properties for optimized tag-to-reader backscatter communication.
The latter is exploited in RF identification (RFID) systems and utilizes binary reflection …

Backscatter radio is proposed for sensor networks. In that way, the transmitter for each
sensor is simplified to a transistor connected to an antenna and therefore, the cost for each …

With rapid advances of scatter radio systems, the principle of reflection rather than active
transmission employed by backscatter sensor networks, has emerged as a potential key …
