APPARATUS AND METHOD FOR DISTRIBUTED PROCESSING OF TRAIN MONITORING TRAFFIC BASED ON HIERARCHICAL WIRELESS SENSOR NETWORK
First Claim
1. An apparatus for distributed processing of train monitoring traffic based on a hierarchical wireless sensor network, the apparatus comprising:
- a wireless sensor node configured to generate sensor data by measuring states of a train;
a wireless mesh network (WSN) manager configured to classify the sensor data into priority data and non-priority data according to change characteristics, and to transmit the priority data to a sensor monitoring center through a wireless communication network and the non-priority data to wireless mesh nodes through a wireless mesh network; and
one or more wireless mesh nodes configured to be spaced apart at predetermined intervals on a railway side, and to transmit the non-priority data, received from the WSN manager, to the sensor monitoring center.
