Abstract :
Nodes in WSN(Wireless Sensor Network) have limited energy. Once they are deployed, it is difficult to supply additional energy. Therefore the routing is most important for using energy efficiently in WSN. The routing protocols of this sensor network have two types: Directed Diffusion and SPIN such as Flat routing protocol, and LEACH (Low-Energy Adaptive Clustering Hierarchy) and LEACH-C (LEACH-Centralized) such as Hierarchical routing protocol. In this paper, we present remaining energy predictable method using computing consumption of nodes and cluster head node from first round to next round for solving LEACH-C problem that all nodes must send current energy level and own location to base station at each round in configuration. When using proposed method through simulation, we can extend the life time of network and lessen total energy of network as reducing a number of communications
