Abstract:
A communication terminal and method is provided for improving channel utilization efficiency in a wireless sensor network using contention-based channel access mechanism is disclosed. The communication method according to the present invention comprises initializing, when a packet transmission is required, a contention window to a size; resetting, when a channel is assessed to be busy, the size of the contention window in a hybrid expansion mode; and attempting, when the channel is assessed to be idle, the packet transmission through the channel.
