Statistical Computation of Harvested Energy for Nano Sensor Network

Autonomous wireless Nano-sensor Network (AWNS) nodes with communication capabilities are envisioned to increase the potential application of individual Nano-sensors. However, as sensing range of individual nanosensors node is limited. Therefore, very high node density is essential to enable different vibrant applications of AWNS. On the other hand, energy storage capacity of nanosensors is the key issue of Wireless Nano Sensor Networks (WNSNs). Therefore, energy harvesting is the foremost requirement of AWNS. Further, random unitary beamforming (RUB)-based cooperative beam selection with Multiuser MIMO is one of the most suitable techniques used to enhance the energy harvesting (EH) performance. In this research we have presented some statistical measures, by virtue of harvested energy. Specifically, we have derived analytical expression for Cumulative Distribution Function (CDF) and outage (Pout) of the system under consideration, by virtue of harvested energy, in which RUB based cooperative beam selection, is used for harvesting. Further, the effect of number of antennas (M), density of interferers (λ) and aggregate power of interferers (γ

) on Pout of harvested energy is presented. For the system under consideration, Probability Density Function (PDF) of harvested energy, amount of harvested energy, throughput and different parameter of secrecy analysis among the others can be analyzed in future.
