The main aim of the work is to analyse, characterize and validate the parameters involved in the system models of the SWIPT enabled Energy Harvesting Wireless Networks. The parameter under this study involves average Energy Harvested, average downlink rate, sensor control signal and Interference.The system model with Fusion Centre and sensors are analysed and respective problem is formulated using BLUE estimation technique. An algorithm is developed to solve for the values of sensor control signal and interference relative to Quality of Service constraints. The effect of channel estimation error in the system model is also included to test the robustness of algorithm. After the formulation of the problem expressions are converted from non-convex to convex for the aim to obtain the global extrema.
