A Method of Networking Hierarchical Sensor Systems for Energy-Saving Robust Sensor Networks

Abstract

We have developed a method for constructing energy-saving sensor networks that are robust against external attacks to the sensor nodes. In our sensor network model, hierarchical sensor systems belonging to different classes that are ranked according to the hardware specifications for wireless communication and electric power source are used to form sensor networks with heterogeneous topological structure. Random attacks to the network cause the deficiencies mainly of terminal sensor nodes of the lowest class, which allows saving energy for establishing communication routes in the network.
