Abstract: In order to detect an unmanned aerial vehicle (UAV) in a monitoring area using a rotatable camera, an integrated sensor configures a first detection area in the monitoring area by rotating the camera after fixing the focal length of the camera to an initial value, and configures a second detection area in the monitoring area by rotating the camera after changing at least one of the focal length of the camera and a rotation path representing a distance from the origin of the monitoring area.

Abstract: A method of retransmitting a packet for low-power wireless sensor communications of a coordinator in a sensor network is provided. The method includes receiving packets from a plurality of sensor devices during a plurality of guaranteed time slots (GTSs) of a Contention Free Period (CFP) which are allocated to the respective sensor devices; checking whether there is an error in each of the received packets; generating one GTS Bulk ACK frame that contains pieces of ACK information to be transmitted to the respective sensor devices, according to the error check results; and transmitting the generated GTS Bulk ACK frame to the plurality of sensor devices.

Abstract: An apparatus for configuring an overlay broadcast network is provided. The apparatus includes: an overlay broadcast server that receives broadcast contents information from a contents server, receives traffic information from a plurality of heterogeneous radio access network, and configures an overlay broadcast network by overlaying the plurality of heterogeneous radio access networks based on the broadcast contents information and the traffic information. The present invention can secure a technology for distributing the load distribution of traffic, securing the broadcast quality by reducing the interference signals, transmitting the multi-screen contents by configuring the overlay broadcast network integrating and using each radio access network under the environment in which various radio access networks are present, increase the frequency use efficiency of the overall radio access network, and save the broadcast communication costs of the user due to the introduction of a virtual mobile communication network provider.

Abstract: An apparatus and method for managing variable MBS zones in an MBS server are provided. The method variably sets an MBS zone based on a characteristic where user movement between MBS zones and content preference are changed depending on time and environment, and thereby enables a safer and faster shift of an MBS zone, thus effectively providing high-quality multimedia service in a mobile environment.
