A Lightweight & Novel Approach for In-Network Aggregation in Wireless Sensor Networks

Sneha Gurnale, P. Malathi

Abstract: Wireless sensor networks (WSNs) have sensing, computation and communications capabilities. Energy conservation is a key issue in WSN. Redundant data can be aggregated at intermediate nodes which can reduce the size and number of exchanged messages. This decreases communication cost, energy consumption and increases the lifetime. For this purpose a modified novel Data Routing for In-Network Aggregation (DRINA) algorithm is proposed for setting up a routing tree and high aggregation rate. To find the shortest path for routing, instead of hop count, distance parameter is considered to reduce the energy consumption, delay, communication cost, and increase the lifetime. Results indicate clearly that with the increase of number of nodes, throughput & lifetime increases and simultaneously delay, energy consumption, and tree cost decreases. Extensive simulations in Network-Simulator 2 show that our protocol outperforms the existing protocols in terms of various performance metrics. Thus the modified DRINA provides the best aggregation quality with respect to other algorithms.
