A Clustering Method of Enhanced Tree Establishment in Wireless Sensor Networks
Source: Sungkyunkwan University
Wireless sensors deliver the data to the Base Station which is collected and monitored at the interested environment. To efficiently transmit the data, some nodes are elected to aggregate the data locally and hierarchically. Recently many cluster-based approaches are proposed. In the proposed technologies, UDACH uses a clustering method which considers the energy of each node instead of selecting cluster head randomly like as LEACH. UDACH consists of three stages such as cluster construction, building a cluster head tree and transmitting the data to the base station. The cluster construction is to select cluster node.
