| Outline of Final Research Achievements |
In this project, we studied fundamental communication theory to realize highly-green and ultimately-reliable ubiquitous wireless sensor networks based on a cross-layer design between physical layer and medium access control (MAC) layer. Specifically, we have proposed a new cooperative communication which enhances the power efficiency at the high power amplifier of the cooperative node. Moreover, two distributed coding techniques have been investigated which can achieve the theoretical limit. Finally, energy harvesting cooperative communications have been proposed. In this cooperation, the cooperative node can scavenge the energy from RF signals emitted by the others and it can be significantly reduces the total energy consumption of the network. These technologies would be key-enablers of the sensor network.
