METHOD OF MANAGING THE DATA-TRAFFIC OF NODE IN SENSOR NETWORK

摘要

A method for managing the data-traffic of node in a sensor network is provided to transmit data traffic in different timing by each node when traffic is simultaneously generated in several nodes with periodical data transmission and periodical polling, thereby reducing data loss. A method for managing the data-traffic of node in a sensor network comprises the following steps of: selecting an allocated network address and a topology depth by a user; computing transmission delay time using the allocated network address and the topology depth when traffic is generated from multiple adjacent nodes(S201,S202); and processing the traffic in sequence by timing according to the computed transmission delay time(S203). The transmission delay time is computed by multiplying the allocated network address by the topology depth.
