PATH RENEWAL METHOD IN FILTERING BASED WIRELESS SENSOR NETWORKS

摘要

PURPOSE: A path renewal method in a filtering based wireless sensor network is provided to reduce power consumption of a sensor node by maintaining protection ability against a false report and transferring data through a well-balanced route. CONSTITUTION: A route of a node is established through a PSM(Path Setting Method) in a wireless sensor network(S1). A reference node is searched along the established route(S2). The residual energy of the reference node is smaller than the reference threshold value. The route of a target node is reestablished among the lower nodes of the reference nodes(S3). The data transfer quantity of the target node is higher than other lower nodes of the reference nodes.
