ZigBee를 활용한 멀티미디어 Contents Delivery 시스템 설계 및 구현

A Design and Implementation of Multimedia Contents Delivery System Using the ZigBee

Recently. as the era of ubiquitous has arrived. an infrastructure for the short-distance wireless communication has been extended socially. and thus a variety of services are being proposed The Multimedia Contents Delivery System using the ZigBee. in particular. has an important stance in enlargement of a variety of services in the aspect of individual-oriented service support though Wireless Personal Area Network (WPAN). Nonetheless. the ZigBee. or the IEEE 802. 15.4 Standard. has many restrictions on the Multimedia Contents Delivery System due to the low data transport rate In order to improve the ZigBee which presents a limit on the transport rate at the IEEE 802.15.4 Standard. this thesis has designed the burst mode which is a method of transmitting a certain amount of data in block units at a high speed without any stoppage until the completion of the transmission. Also. to provide a Multimedia Contents Delivery Service with an application of the normal data transmission mode. it improved the transmission performance of the ZigBee. In addition. lor the Multimedia Contents Delivery Service under the ubiquitous environment. it designed and implemented a broadcasting Multimedia Contents Delivery System based on the ZigBee to conduct a comparative analysis on the data transmission performance according to the transmission method.
