Abstract: Wireless Sensor Networks consist of large number of sensors which are deployed close to the proximity which is to be monitored. Sensors are energy-constrained devices, so it is very important to design a routing protocol for transmitting the aggregated data to the sink node effectively. In this paper, a novel approach called EDRINA (Enhanced Data Routing for In-Network Aggregation) is proposed. EDRINA forwards data using spanning tree in the cluster, where cluster head is elected using forward aware technique, towards the destination node. It has features like maximized data aggregation rate, low cost, low overhead, thus improves the network lifetime by reducing energy consumption. EDRINA is compared with Data Routing for In-Network Aggregation (DRINA), Shortest Path Tree (SPT) and Information Fusion based Role Assignment (InFRA) algorithms using Network Simulator and is proved to be outperforming in all the evaluated scenarios.
