MODEL FOR SOLAR ENERGY HARVESTING AND OPTIMIZATION IN WIRELESS SENSOR NETWORKS

Presented in this thesis is the energy harvesting and management model concerning wireless sensor network. Wireless sensor network, bears resemblance as routers. However, wireless sensor network cannot afford large batteries because of their small size. Continues operation of these devices result in rapid consumption of available energy. It is difficult to replace and recharge the battery due to limited accessibility. Sometime these devices are installed in remote areas or areas with uneven terrain such as hilly areas. One approach to counter this problem is to harness the ambient energy which is unevenly distributed in our environment. Availability of this energy is random and uncertain. Ambient energy has been successfully harnessed by solar energy harvesting technique. We present a feasible approach of management model with appropriate energy management for wireless sensor network. The proposed solar energy harvesting and management model not only saves energy, it also assures the connection and communication within the network by optimum consumption of energy along with the management of the harvested and battery energy.
