Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system. Disclosed is a method of receiving a video segment from at least one streaming server by a client device using hypertext transfer protocol (HTTP) adaptive streaming in a wireless network. The method includes: acquiring media presentation description (MPD) information by receiving an MPD file from the streaming server and parsing the received MPD file; determining a first parameter to minimize a cost function considering both energy consumption required for receiving a video segment and video quality of the segment based on the MPD information; requesting at least one video segment to the at least one streaming server during a first segment request round based on the first parameter; and receiving the at least one video segment from the at least one streaming server.

Abstract: The present invention relates to a hybrid storage system combining a cloud storage system and a P2P storage system. The hybrid storage system comprises: a node management unit for measuring bandwidths for a cloud storage system server and a P2P storage peer; a variable control unit for calculating a packet distribution vector for determining the unit of data to be dispersed in the sever and the peer and a fountain coding rate for determining encoding for data to be stored in the server and the peer; an encoding unit for fountain-encoding data to be stored in the server and the peer, according to the foundation coding rate; and a scheduler for calculating a transmission time which is the time required for data transmission to the server and the peer on the basis of the measured bandwidths and the packet distribution vector, and transmitting information on the transmission time to the variable control unit.
