Abstract- Wireless Sensor Networks are equipped with batteries with limited charge, and are often deployed in conditions that make their retrieval and replacement infeasible. Wireless Sensors, especially used for surveillance at the warfront in defense along with combat equipment and Walkie Talkies do not have access to electric grid and hence face a cumbersome uphill task of charging. One of the major bottlenecks of Wireless Sensor network is, ensuring that the power is maintained at the sensor nodes. Our method would be most effective to energy populate large sensor networks of the order of 100’s and
1000’s which are placed in remote locations far from the electric grid. This proposed system can also be used to deliver power wirelessly by a swarm of mobile carrier hosts in case of an emergency like an earthquake disaster when all the electric grids and electric lines collapse. In this work a new “mobile carrier hosts” delivered paradigm is presented. Wireless power transmission to sensors by mobile carrier hosts such as UAV’s (Unmanned Aerial Vehicle)take place at medium ranges as per the need of the nodes. The mobile carrier hosts or UAV may be used to provide power to and recharge any group of remotely located deployed nodes and other electronic devices simultaneously that need energy or are required to be interrogated. Compared to existing approaches, this technology can replenish energy in a more controllable and efficient manner. In this paper we design such a system, build a prototype to evaluate its feasibility and performance in small-scale networks, and study its practicality in large-scale networks.To enhance the power transfer efficiency for larger distances, anefficient wireless power transfer schemeusing passive repeaters is
