Data Aggregation in Wireless Sensor Networks

The basic role of a wireless sensor network is to collect information from the environment by many sensor nodes (SNs). The SN typically has a finite battery life and nodes' failures can lead to network partition. Therefore, it is important to minimize the energy usage of each sensor node and to manage the power of SN in critical position that their failure could divide the network. This drives research on how to design routing protocols to gather data efficiently, so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multi-hop. To resolves the problems, a new energy balanced and efficient data aggregation scheme for WSN is used. With a predetermined set of paths based on the specific Application.
