In robotics and telecommunications world, wireless sensor networks are an active research area with numerous real life applications, R&D and industrial area. Wireless Sensor Networks consist of small nodes with sensing, computation and wireless communications capability. Wireless Sensor Networks (WSNs) have been widely deployed for various applications, such as environment sensing, military and medical, traffic monitoring, habitat monitoring, building safety monitoring and earthquake prediction. In general WSN architecture, storage nodes aggregate data from nearby sensors and answer queries from the sink of the network which is also called as two-tiered WSN architecture.
