Abstract: Provided is a machine type communication system including a machine type communication device operating with a battery. The machine type communication system may monitor a residual power of the battery supplying power to the machine type communication device, and may output the monitored residual power to a device of a manager that manages the machine type communication device. Also, a point in time when the residual power of the battery is to be monitored may be determined based on the residual power.

Abstract: The present invention provides a method and system for performing distributed channel sensing in which channel information is collected by performing channel sensing according to a channel sensing priority which is determined according to a relative position of a cell to which a wireless connection device belongs from among a plurality of cells which logically partition the zone of the wireless network, and thus the overhead of the channel sensing which is generated in a cognitive wireless multi-hop network environment is reduced, and the transmission failure which occurs when the wireless connection device detects frequencies is reduced.
