Dependable Routing Approach for In-Network Aggregation in Wireless Sensor Network

Wireless sensor networks create a lot of information that needs to be proceeds, delivered, and evaluated as per the application goals. The way this information is controlled by the sensor nodes is a key issue. Data fusion emerges as a reaction to process information accumulated by sensor nodes and profits from their preparing capacity. Data-centric technologies are needed that perform in-network aggregation of data to yield energy-efficient dissemination. For precise monitoring, extensive scale dense Wireless Sensor Networks (WSNs) will be progressively deployed in diverse classes of uses. It is likely that redundant data will be identified by adjacent nodes when sensing an event, because of the high thickness of nodes in these systems. Since energy preservation is a key issue in WSNs, in order to save energy data fusion and aggregation ought to be abused. In this case, redundant data can be aggregated at intermediate nodes reducing the size and number of exchanged messages and, thus, decreasing communication costs and energy consumption. There is requirement of novel Routing for In-Network Aggregation which have some features like high aggregation rate, and reliable data aggregation and transmission, reduced number of messages for setting up a routing tree, maximized number of overlapping routes and best aggregation quality.
