APPARATUS AND METHOD FOR A TOPOLOGICAL PHASE TRANSITION FOR WIRELESS SENSOR NETWORK

摘要

PURPOSE: A device and a method for a biology inspired topological phase transition for wireless sensor networks (WSN) are provided to change the topologies of wireless sensor networks according to activity patterns and resources of wireless sensor nodes, thereby forming an energy-efficient, adaptive and self-organizing network. CONSTITUTION: A wireless sensor node for a wireless sensor network comprises a plurality of the wireless sensor nodes. The wireless sensor node comprises a controller (510) for controlling operations of the node; a transmitter for transmitting communications from the node; a receiver (530) for receiving communications; a sensor (540) for sensing sensor data; and a memory (550) for storing the sensor data. The controller controls the node to connect to other nodes or to an external WSN access point in accordance with a determined optimal topological phase of the WSN.
