¿µ¹®³»¿ë¿ä¾à | The concept of Touch-And-Play (TAP) has been introduced to provide convenient service based on Body Area Communication Technologies. The purpose of TAP is to provide information at the time of necessity because touching means that users need and are interested in some specific services at that time. For example, when a user with digital camera touches printer device, the pictures in camera might be printed on the printer without pressing a series of command keys. In a human body communication network, multiple transmitting/receiving devices may collide for the medium (body). So MAC protocol is necessary to resolve the collision for transmission medium. This specification defines and describes a MAC protocol for human body communication networks which supports multicast communication and network-merging. | ||
