GDA: Gravitational Data Aggregation Mechanism for Periodic Wireless Sensor Networks

This paper proposes a novel on-node data aggregation mechanism inspired by Newton's law of gravity. The proposed mechanism is on-node and filters out the redundant data points at the data source (sensor nodes) in periodic wireless sensor networks (WSNs). Analysis reveals that proposed mechanism is suitable for the transient sensor data and significantly reduces the number of message exchanges between sensor node and the next hierarchical node in the network.
