¿µ¹®³»¿ë¿ä¾à | The Wearable computer is one of major technologies to make ubiquitous
computing environment feasible. Various researches on the wearable computer are currently being carried out. One of such efforts is to build a communication network on a clothes and to connect various devices embedded in the clothes. A communication network which covers a body area in the wearable computing environment is called the WPN(Wearable Personal Network). WPN may be implemented by using either a wire line or wireless media. WPN using wireline is specially called the e-Textile Network. Most of the researches on the WPN are those which uses the wireless communication technology from IEEE 802.15. Study on the wired WPN has not been carried out enough worldwide. Therefore e-Textile Network needs standardization. This standard specification defines the requirements, network topology and protocol for the e-Textile Network which is a wired WPN embedded in a clothes. Requirements are prescribed by analyzing the characteristics of e-Textile Network environment. The bus network topology is used considering the requirements of wired WPN. The protocol defined in this specification is a data link layer protocol and is mainly for connecting peripheral devices to a host computing device. Both the synchronous protocol and the asynchronous protocol are defined. Synchronous protocol may be used in a nertwork where peripheral nodes do not have CSMA(Crrier Sense Multiple Access) capability. This specification also prescribes a node discovery protocol that can be used both for a network with CSMA and for a network without CSMA accessing technology. The discovery protocol enables the host to recognize and search for a node which is newly added to the network or removed from the network without the users¡¯ intervention. |
