Method for allocating slots for emergency data and method for transmitting emergency data using the same

Abstract

There are provided a method for allocating slots for emergency data and a method for transmitting emergency data using the same. The method for allocating slots for emergency data may be configured to include: allocating slots for emergency data to superframes that are configured to include a beacon period indicating a start of the superframe, a contention access period (CAP) transmitting data through contention, and a contention free period (CFP) transmitting data without contention; and providing slot allocating information on the emergency data to nodes. As a result, the method for allocating slots for emergency data allocates the separate slots for the emergency data while avoiding the contention access period (CAP) frequently used, which are used in the inter-node contention mode to enable the plurality of nodes to use one slot for one emergency data. In particular, even though there may be the risk of transmission failure due to the contention mode, the occurrence frequency of the emergency message, or the like, is low, which results in a similar effect to allocating the dedicated slots for the emergency data to the plurality of nodes while avoiding the transmission failure.
