  • Publication number: 20150036588
    Abstract: In a wireless sensor network, it is determined whether to multiplex a packet that is generated in a random node. When a packet is to be multiplexed, by multiplexing at least one packet, a frame of a first length is generated and transmitted. The frame of the first length includes a payload in which at least one of data portions including a header unit and a data unit having a second length smaller than the first length is multiplexed.

  • Publication number: 20150019718
    Abstract: Disclosed are methods for service discovery in a wireless personal area communication network. A method for service discovery, performed in a terminal, the method comprises performing a passive scan for searching a specific service based on whether to receive a frame including a specific service identifier; and, when it fails to search the specific service, performing an active scan which broadcasts a service discovery request command frame for searching the specific service. Thus, service discovery may be efficiently performed by reducing the operation complexity of the terminal and minimizing the power consumption of the terminal needed for service discovery, without support of a upper layer.

  • Publication number: 20140341206
    Abstract: According to an exemplary embodiment of the present invention, a method for time synchronization of a first node in a peer aware communication (PAC) environment is provided. The first node obtains medium access control authority by performing contention with a second node neighboring the first node. The first node adds a time synchronization offset to the first beacon frame. In addition, the first node transmits the first beacon frame in a beacon period of a superframe when obtaining the media access control authority.
