The Implementation of Non-Coherent Cooperative Transmission for Wireless Sensor Networks

Traditional approaches using superimposed signals in wireless sensor networks have high demands on the hardware capabilities of a single network node. In this demo, a practical implementation of a non-coherent cooperative transmission system is showed in a real hardware implementation. For the feasibility and practical implementation an additional modification on the current theory in the literature was necessary. The demo shows how a group of sensor nodes can increase their transmit range by using simultaneous transmission to sum up their power as a group. To our knowledge, this is the world’s first implementation of non-coherent cooperative transmission.
