Routing Method for Transmitting Emergency Data based on Priority Q and Network System using the same

摘要

PURPOSE: A routing method and a network system applying the same are provided to reduce the degradation of the entire performance due to queuing delay time of an existing wireless sensor network. CONSTITUTION: Queuing delay time is calculated for transmitting first priority data to a sink node(S110). The calculated queuing delay times are compared(S120). A path for transmitting the first priority data is selected. The first queuing delay time is calculated for transmitting the first priority data to the sink node. If the first queuing delay time exceeds a requested reference time, scheduling wait about the first priority data increases(S130).
