Power Optimization of Wireless Sensor Networks Using Encryption and Compression Techniques

Wireless sensor networks consists of collection of autonomous sensors distributed at different geographical locations. Wireless sensor networks are mainly used to measure and monitor environmental and physical conditions such as sound, pressure, temperature, and lot more. Wireless Sensor networks has gain its popularity in recent years and is most widely used. The reason behind is popularity is that it can sense and monitor the physical and environmental conditions in the area where human reach is ruled out. These sensors sense the conditions and wirelessly transmits the data to the base station. The base station is nothing but a router which receives the data from various such wireless sensor networks. The various sensor networks which transmits the data to base station is called as nodes. When these nodes sends the data to the base station, an energy has been utilized by these nodes to transmit the data similarly energy is also utilized by the router to route the data to other nodes. By means of this paper, the energy consumed by the nodes and base station to transmit the data to each other has been optimized by using a combination of compression and encryption techniques on data to be transmitted.
