    • PURPOSE: A communications control method of power line communications network is provided to control a communications group which uses various power line communications protocols to be coexisted in the power line communications network. CONSTITUTION: A communications control method of power line communications network comprises the following steps: a node selects oneself as a representative node in case selected representative node does not exist(S10,S20); the representation node receives PCL information(power line communications information) of each communications group from designated node of surrounding communications groups which coexist in the PLC network(S30); the representative node transmits assigned communications group identifiers to the designation nodes of each communications group(S40); the representation node synchronizes the power line communications network(S50); and the representation node allocates calculated communications resources to each communications group(S60).

    • The present invention relates to a method for controlling the sleep time of a mobile sensor node in an IEEE 802.15.4-based sensor network. More specifically, the invention relates to a method for controlling the sleep time of a sensor node, which makes it possible to reduce the energy consumed by the sensor node by increasing the sleep time of the sensor node in stepped fashion depending on whether there is any data to be sent or received between the sensor node and a gateway instead of having the sensor node unconditionally wake up or receive beacon messages in every send cycle of beacon messages sent from a gateway, and by maintaining the sleep time of the sensor node even when the sensor node moves to a neighbouring gateway. The method for controlling the sleep time of a sensor node according to the present invention makes it possible to reduce the energy consumed by the sensor node by increasing the sleep time of the sensor node in stepped fashion depending on whether there is any data to be sent or received between the sensor nodes and a gateway. In addition, the method for controlling the sleep time of a sensor node according to the present invention makes it possible to reduce the energy consumed by sensor nodes in a sensor network in which sensor nodes frequently move, by maintaining the sleep times of the sensor nodes even when the sensor nodes move and gain access to neighbouring gateways.
