A Clustering Topology Control Method using Second Order Formation with 2 Level Transmission Power in USN

摘要

The present invention provides a method for managing a sensor clustering topology of sensor nodes having a dual transmission range. In a method of configuring a sensor network in a USN environment, a cluster is formed using a transmission power variable node having a dual transmission range. Making a first step; And a second step of grouping adjacent node sets having the same hop count level into a cluster after the first step; and configuring a network around nodes having two transmission ranges to reduce load on each node. Energy efficiency can be improved while maintaining connectivity between the network and the entire network.;USN, cluster, topology, transmission range, sensor node
