A Clustering Method of Enhanced Tree Establishment in Wireless Sensor Networks

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. In the next stage, the cluster heads form tree structure to transmit multi-hop through the parent cluster head. However, if the parent cluster head is not selected appropriately, UDACH dissipates the energy because the total distance of transmission to the BS is longer. In this paper, we propose A Clustering Method of Enhanced Tree Establishment to construct tree structure for the optimized energy consumption. Through the simulation, we describe that the proposed scheme is more effective than LEACH and UDACH routing protocol.
