IEEE 802.22 is the first world-wide standard for wireless regional area networks using cognitive radio technologies. Major drawbacks of these networks are limited network capacity and low energy efficiency. One potential solution for these drawbacks is device-to-device communication, which can be incorporated as D2DWRAN. D2DWRAN features direct intracell communication, reuse of channels, and use of...
Powering wireless sensors with harvested energies is coming of age due to the sources providing higher power densities and the electronics performing efficient energy conversion. However, to ensure energy harvesting as a viable option, several system parameters have to be tuned. In this work, we identify these key system parameters and show that by suitably tuning them, one can drive wireless sensor...
